POISONED WATER: How Rachel Levine tried to block the nasty truth about fluoridation’s devastating effect on childhood IQs
( Natural News ) Covid showed us how corrupt the medical establishment has become not only in America but worldwide. Doctors know where their bread is buttered and rarely speak out of school or provide advice based on their own independent research. They will support almost any government health narrative if that’s what it takes to make sure the money continues to flow, even if it means violating their oath to “do no harm.”

Next in line for top honors in terms of corruption, after the biomedical-security complex, is the media.
People say the truth will always prevail, and I agree. But this is a lesson that governments never seem to learn, especially when they have a corrupt media willing to cover for their lies.
We see the government and media colluding to deceive the masses on vaccines (they’re safe and effective, safe and effective, safe and effective). We see them colluding on the phony climate change narrative, where to save the planet you’ve got to grow less food, exchange real meat for fake, eat bugs, curtail freedom of movement, digitize humanity and convert all power generation to the electric grid, which is already overtaxed. We see it with so-called “gun violence” — blame the tool not the evil people who misuse the tool. And the list goes on.
But nowhere has the government-media collusion to deceive been going on longer than when it comes to the deliberate poisoning of America’s municipal drinking water. They poison it right at the source, then tell you that it’s good for you. It builds strong teeth!
The final report of an exhaustive six-year study of fluoride neurotoxicity was blocked from public release by Biden appointee Dr. Richard “Rachel” Levine at the U.S. Department of Health and Human Services in May 2022, according to the Fluoride Action Network . Dr. Richard “Rachel” Levine The exhaustive study, conducted by the National Toxicology Program (NTP), included incontrovertible evidence that fluoride hinders the development of the brain in children who consume it at levels present in most public water systems.
But under an agreement reached in an ongoing lawsuit against the EPA, the report was finally made public on March 15 of this year with a table of contents . Included were comments from external peer-reviewers and internal HHS departments, along with responses from the National Toxicology Program.
The review considered all human studies of fluoride’s effect on the developing brain. Its conclusion confirmed and strengthened the findings from two earlier drafts released in 2019 and 2020 . External peer-reviewers all agreed with the conclusion that prenatal and early life fluoride exposures can reduce IQ.
The report was issued in two parts, a monograph and a meta-analysis. The meta-analysis found that 52 of 55 studies found lower IQ with higher fluoride exposures, demonstrating remarkable consistency. Of the 19 studies rated higher quality, 18 found lowering of IQ. The meta-analysis could not detect any safe exposure, including at levels common from drinking fluoridated water.
Documents obtained through the Freedom of Information Act show government agencies that promote fluoridation, most allied with dental interests, have tried to water down the report, according to a release by Fluoride Action Network.
In the excerpt from the March 15 press release below, the Fluoride Action Network specifically names “ Rachel Levine ,” a gender-confused man, as the government official who tried to block the truth from coming out on the havoc fluoride continues to wreak on children’s brains. It took a lawsuit to force this information from the secret files of the government. The release states:
When the NTP held firm, these agencies got HHS Assistant Administrator Rachel Levine to block its release . Only one historical example exists of an NTP report being blocked from release, a report on the carcinogenicity of asbestos-contaminated talc. Talc industry groups conducted an aggressive lobbying campaign, enlisting friendly congresspeople to intervene. FAN was able to force today’s release of the NTP report by using leverage from the ongoing lawsuit against the EPA.
Fluoridation defenders have falsely claimed draft versions of the report had been “rejected” by a National Academies committee. In fact, the committee recommended that NTP clarify their methods and reasoning for reaching their conclusions because the issue was considered so contentious. The NTP has done that in the report released today. There is now little question that a large body of scientific evidence supports a conclusion that fluoride can lower child’s IQ, including at exposure levels from fluoridated water.
With the release of this report, dental interests may have to rethink their denial of the evidence that fluoridation can reduce children’s IQ.
Dentists have for decades pressured their customers to use fluoridated toothpaste while lobbying for fluoridated drinking water, despite reams of evidence showing this is a toxic chemical that provides little if any benefit to dental health. Most common water filters do not remove fluoride and the ones that do are more expensive, but worth the money, especially if you have children under your care.
So, where does fluoride come from, anyway? It’s an industrial-waste byproduct of the mining industry, explains Frank Zelko, in an article for the Ohio State University website Origins .
Zelko writes:
“Highly toxic hydrogen fluoride and silicon tetrafluoride gases are by-products of fertilizer production. Prior to the 1970s, these pollutants were vented into the atmosphere and gave central Florida some of the most noxious air pollution in the country. During the 1960s, however, complaints by farmers and ranchers eventually forced reluctant manufacturers to invest in pollution abatement scrubbers that converted toxic vapors into fluorosilicic acid (FSA), a dangerous but more containable liquid waste.”
Zelko further explains that the U.S. National Institute for Occupational Safety and Health (OSHA) cautions that FSA, an inorganic fluoride compound, has dire health consequences for any worker that comes into contact with it.
“Breathing its fumes causes severe lung damage or death and an accidental splash on bare skin will lead to burning and excruciating pain. Fortunately, it can be contained in high-density cross-linked polyethylene storage tanks.”

Memory loss ‘can be reversed by simple diet changes’
Memory loss can be reversed by increasing intake of foods such as green tea, apples and berries, new research suggests.
The study is the first to show that a diet with insufficient flavanols – nutrients found in certain fruits and vegetables – stops the brain functioning at its best, and drives memory loss.
Flavonols are present in many foods including green leafy vegetables, blackcurrants, onions, apples, berries, cherries, peaches, soybeans, citrus foods, tea, chocolate, lettuce, peppers, grapes and even wine.
The study by US researchers found that over-60s who already consumed sufficient flavanols saw no benefit when they added more, but those with deficits recorded memory improvements of an average of 16 per cent in a year.
“The improvement among study participants with low-flavanol diets was substantial and raises the possibility of using flavanol-rich diets or supplements to improve cognitive function in older adults,” said Dr Adam Brickman, professor of neuropsychology at Columbia University.
Experts said the finding supports the idea that the ageing brain requires specific nutrients to stay functioning well, just as the developing brain of children requires specific nutrients for proper growth.
Previous studies in animals have shown that flavanols boost the growth of neurons and blood vessels in the hippocampus – a region of the brain which is crucial for learning and developing new memories.
For the study, more than 3,500 healthy older adults were randomly assigned to receive a daily flavanol supplement pill or placebo pill for three years.
The active supplement contained 500 mg of flavanols, a daily amount that adults are advised to get from food.
Such a dose could be achieved naturally through one mug of tea, six squares of dark chocolate , and a couple of servings of berries or apples. ‘Really important’ research
At the beginning of the study, all participants completed a survey that assessed the quality of their diet, and performed a series of web-based activities in their own homes, designed to test their short-term memory.
The tests were then repeated after years one, two, and three.
At the end of the first year of taking the flavanol supplement, participants who reported consuming a poorer diet and had lower baseline levels of flavanols saw their memory scores increase by an average of 10.5 per cent, compared to those who took the placebo pill, and 16 per cent compared to their memory at baseline.
And the improvement lasted for at least two more years.
Commenting on the research, Prof Aedin Cassidy, Chair in Nutrition & Preventative Medicine at Queen’s University Belfast (QUB), said: “This is a really important study showing that [a] dose of flavonoids called flavanols, present in tea, cocoa, apples, and berries, is key for improving memory in the ageing brain.
“Supplementing with flavanols reversed the lower memory in the participants who had low diet quality after one year of intake and this was sustained throughout the three year intervention period.
“So when habitual diets are not as healthy as they could be, we now have evidence that simple additions to the diet like flavanols can contribute to maintaining brain health as we age.”
The team said they could not definitively conclude that low dietary intake of flavanols alone causes poor memory performance, because they did not conduct an experiment where they removed flavanol to see if it made memory worse.
To find out for sure, they now want to conduct a clinical trial in which they restore flavanol levels in adults with severe flavanol deficiency to see if it improves memory.
“Age-related memory decline is thought to occur sooner or later in nearly everyone, though there is a great amount of variability,” said Dr Scott Small, Professor of Neurology at Columbia University.
“If some of this variance is partly due to differences in dietary consumption of flavanols, then we would see an even more dramatic improvement in memory in people who replenish dietary flavanols when they’re in their 40s and 50s.”
The research was published in the journal PNAS.

Rhythmically stimulating the brain with electrical currents could boost cognitive function, according to analysis of over 100 studies
(THE CONVERSATION) – Figuring out how to enhance a person’s mental capabilities has been of considerable interest to psychology and neuroscience researchers like me for decades . From improving attention in high-stakes environments, like air traffic management, to reviving memory in people with dementia, the ability to improve cognitive function can have far-reaching consequences. New research suggests that brain stimulation could help achieve the goal of boosting mental function.
In the Reinhart Lab at Boston University, my colleagues and I have been examining the effects of an emerging brain stimulation technology – transcranial alternating current stimulation, or tACS – on different mental functions in patients and healthy people.
During this procedure, people wear an elastic cap embedded with electrodes that deliver weak electrical currents oscillating at specific frequencies to their scalp. By applying these controlled currents to specific brain regions, it is possible to alter brain activity by nudging neurons to fire rhythmically .
Why would rhythmically firing neurons be beneficial? Research suggests that brain cells communicate effectively when they coordinate the rhythm of their firing. Critically, these rhythmic patterns of brain activity show marked abnormalities during neuropsychiatric illnesses. The purpose of tACS is to externally induce rhythmic brain activity that promotes healthy mental function, particularly when the brain might not be able to produce these rhythms on its own.
However, tACS is a relatively new technology, and how it works is still unclear. Whether it can strengthen or revive brain rhythms to change mental function has been a topic of considerable debate in the field of brain stimulation. While some studies find evidence of changes in brain activity and mental function with tACS, others suggest that the currents typically used in people might be too weak to have a direct effect.
When faced with conflicting data in the scientific literature, it can be helpful to conduct a type of study called a meta-analysis that quantifies how consistent the evidence is across several studies. A previous meta-analysis conducted in 2016 found promising evidence for the use of tACS in changing mental function. However, the number of studies has more than doubled since then. The design of tACS technologies has also become increasingly sophisticated .
We set out to perform a new meta-analysis of studies using tACS to change mental function. To our knowledge, this work is the largest and most comprehensive meta-analysis yet on this topic, consisting of over 100 published studies with a combined total of more than 2,800 human participants.
After compiling over 300 measures of mental function across all the studies, we observed consistent and immediate improvement in mental function with tACS. When we examined specific cognitive functions, such as memory and attention, we observed that tACS produced the strongest improvements in executive function , or the ability to adapt in the face of new, surprising or conflicting information.
We also observed improvements in the ability to pay attention and to memorize information for both short and long periods of time. Together, these results suggest that tACS could particularly improve specific kinds of mental function, at least in the short term.
To examine the effectiveness of tACS for those particularly vulnerable to changes in mental function, we examined the data from studies that included older adults and people with neuropsychiatric conditions. In both populations, we observed reliable evidence for improvements in cognitive function with tACS.
Interestingly, we also found that a specialized type of tACS that can target two brain regions at the same time and manipulate how they communicate with each other can both enhance or reduce cognitive function . This bidirectional effect on mental function could be particularly useful in the clinic. For example, some psychiatric conditions like depression may involve a reduced ability to process rewards, while others like bipolar disorder may involve a highly active reward processing system . If tACS can change mental function in either direction, researchers may be able to develop flexible and targeted designs that cater to specific clinical needs.
Developments in the field of tACS are bringing researchers closer to being able to safely enhance mental function in a noninvasive way that doesn’t require medication. Current statistical evidence across the literature suggests that tACS holds promise, and improving its design could help it produce stronger, long-lasting changes in mental function.

Health officials delayed report linking fluoride to brain harm
Last May, the National Toxicology Program (NTP), a federal research agency, was set to release its eagerly awaited report into the cognitive and neurodevelopmental impacts on humans from fluoride exposure.
The report was anticipated for several reasons, including its review of studies linking fluoridated water to cognitive harm in children. Water fluoridation is the long-established public policy of adding fluoride to drinking water to fight tooth decay. The report was also set to play a key role in an ongoing lawsuit , filed by government accountability nonprofit Food & Water Watch, to get the Environmental Protection Agency to regulate water fluoridation because of fluoride’s possible neurotoxic harm. More than two years ago, the judge put the case on hold in expectation of the NTP report’s public release.
Before the NTP could release the report, however, “They were blocked,” said Linda Birnbaum, NTP director until 2019. According to Freedom of Information Act (FOIA) records obtained by the plaintiffs and shared with Capital & Main, the U.S. Department of Health and Human Services (HHS) held back the release of the report after criticism of its findings from health and dental organizations that advocate for community water fluoridation. Those groups challenged the report’s scientific validity and expressed concern that it could jeopardize water fluoridation, which they said could especially impact the dental health of low income communities.

The report found that a link between typical levels of fluoride added to water and possible harm to brain development is unclear, with a recommendation for more studies, according to records. But the report did find a possible link to cognitive harm at approximately two times the current recommended water fluoridation level, records show. Some health experts believe this finding makes current water fluoridation levels potentially unsafe for developing fetuses and young children. Because many common foods and drinks contain fluoride, consuming them along with fluoridated water could amount to harmful exposure levels, these experts say.
Leading up to the report’s intended release, individuals from dental organizations including the American Dental Association (ADA) scrutinized the report’s scientific credibility in communications with staff from other dental groups and health agencies including the National Institutes of Health and the NTP, divisions of HHS, records show.

This January, Birnbaum issued a scathing legal declaration as part of the lawsuit, writing, “The decision to set aside the results of an external peer review process based on concerns expressed by agencies with strong policy interests on fluoride suggests the presence of political interference in what should be a strictly scientific endeavor.” Birnbaum said she issued the legal declaration in part over concerns the report might never be publicly released.
The NTP has announced that it will now release the report on March 15, alongside an updated version of the same document that includes the NTP’s responses to what it describes as a “significant number” of comments and criticisms received from experts at various federal health agencies.
Birnbaum, however, remains adamant that the science proves there is “no real benefit” from ingesting fluoride. “The benefit from fluoride is from topical applications,” she said.

Water fluoridation is described as one of the 10 greatest public health achievements of the 20th century for its part in reducing tooth decay in adults and children by roughly 25%. According to the latest figures , nearly 73% of people connected with community water systems receive fluoridated water, accounting for more than 200 million people, or just under two-thirds of the overall U.S. population. Advocates argue that fluoridation is especially needed in low income communities where rates of tooth decay are generally higher than in wealthier neighborhoods.
At the same time, a growing body of research links fluoride exposure to neurotoxicological impacts in humans, including IQ loss and a higher prevalence of ADHD in children.
The NTP has been working since 2016 on its systematic review of the science into these impacts. By the time the report was set for release last May, it had already undergone more rounds of peer review than is typically the case for such a document, court records show — twice with the National Academies of Sciences, Engineering, and Medicine (NASEM), and external peer review by five experts in the field. According to Birnbaum, similar reports are typically sent out for public comment, peer reviewed by an on-site panel, then finalized by the NTP.

Despite this unusually rigorous review process, a network of health officials and influential dental groups argued that the NTP had failed to address several issues raised by the NASEM review committee. These issues include a need to consider more studies in the review, and a failure to properly account for bias among some of the studies selected. One key health official wrote that if the Centers for Disease Control and Prevention (CDC) had been given the option to clear the report, “We would have non-concurred,” records show.
Birnbaum said she strongly disagrees that the NTP had failed to address NASEM’s concerns. In her declaration, Birnbaum wrote that various sources told her the five external peer reviewers agreed with what was then the final report’s conclusions, and that “NTP’s staff and leadership considered the monograph to be complete and ready for publication by May 2022.”
The report’s critics also feared its findings could erode public trust in water fluoridation, with the head of one leading dental research organization calling it “potentially very bad fluoride news.”

In April of last year, American Fluoridation Society President Johnny Johnson wrote an open letter to “Oral Health Advocates and Public Health Leaders” warning how the NTP’s findings were already causing public health officials to second guess their stance on community water fluoridation (CWF).
“In at least one U.S. state the NTP’s draft Monograph has led to that state’s Toxicologist not being willing to support CWF as safe, when in the past that same Toxicologist was supportive. This is directly due to the NTP’s report,” Johnson wrote.
In response to questions, Johnson wrote in an email that “since the NTP report is not yet publicly available, it would be premature to comment on something that […]
Can multivitamins improve memory? A new study shows ‘intriguing’ results
The brain requires a large number of nutrients for optimal health and efficiency, but micronutrients are typically absorbed better through foods than through supplements. Americans spend billions of dollars on supplements each year, and roughly 1 in 3 adults report taking a multivitamin. But there is a debate about whether this helps promote good health.
A team of researchers wanted to assess how a daily multivitamin may influence cognitive aging and memory. They tracked about 3,500 older adults who were enrolled in a randomized controlled trial. One group of participants took a placebo, and another group took a Silver Centrum multivitamin, for three years. The participants also took tests, administered online, to evaluate memory.
At the end of the first year, people taking a multivitamin showed improvements in the ability to recall words. Participants were given lists of words — some related, some not — and asked to remember as many as possible. (List-learning tests assess a person’s ability to store and retrieve information.)
People taking the multivitamin were able to recall about a quarter more words, which translates into remembering just a few more words, compared to the placebo group.
“We estimate that the effect of the multivitamin intervention improved memory performance above placebo by the equivalent of 3.1 years of age-related memory change,” the authors write in their paper, which was published this week in the American Journal of Clinical Nutrition . And the authors point to a sustained benefit.
“This is intriguing,” says Dr. Jeffrey Linder, chief of general internal medicine at Northwestern University Feinberg School of Medicine, who was not involved in the study. But he says the overall effect found in the study was quite small. “It seems like a pretty modest difference,” Linder says. And he points out that the multivitamins had no effect on other areas of cognition evaluated in the study, such as executive function, which may be more important measures.
Study author Dr. JoAnn Manson , who is chief of the division of preventive medicine at Brigham and Women’s Hospital, says this is not the first study to show benefits from multivitamins. She points to a study published last year in Alzheimer’s & Dementia that showed participants who took a daily multivitamin performed better, overall, on global cognitive function on tests measuring story recall, verbal fluency, digit ordering, as well as executive function.
“It is surprising that such a clear signal for benefit in slowing age-related memory loss and cognitive decline was found in the study, ” Manson says. “Those receiving the multivitamin did better than those receiving the placebo.”
Our bodies and brains require many nutrients for optimal health and efficiency. Manson says if people have deficiencies in these nutrients it may influence memory loss or speed cognitive decline. So, she says taking a multivitamin may help someone prevent a deficiency if they’re not getting all the nutrients they need from their diet.
“It’s important to highlight that a multivitamin will never be a substitute for a healthy diet,” Manson says, since micronutrients are typically better absorbed through foods than through supplements.” But it may be a complementary approach or strategy for maintaining cognitive health among older adults,” she says.
Linder says he will continue to tell his patients that if they eat a healthy diet they are unlikely to benefit much from a multivitamin. “If you’re taking too much of a particular supplement and your body doesn’t need it, you’re just peeing it out,” he says. He wrote an editorial, published in JAMA, arguing that vitamins and supplements could be a waste of money for a lot of people. He argues that we should help people adopt a better pattern of eating.
“Eating a diet that has plenty of fruits and vegetables is associated with longevity and better function and better quality of life,” Linder says. There’s plenty of research to show a healthy diet is linked to better heart health, and when it comes to protecting cognitive function, “the current thinking is that all of the stuff that’s good for your heart is also good for your brain,” he says.
When Linder talks to his patients about healthy aging, he focuses on good sleep habits, physical activity and a healthy diet. “My big concern with all of the focus that people have on vitamins is that it’s distracting them from things that actually will help them stay healthy,” Linder says.
“If someone is taking a multivitamin, I’m not going to tell them to stop,” says Dr. R. Sean Morrison , who is a geriatrician at Mount Sinai Health System in New York. But he says he would not encourage the use of multivitamins as a way to protect against memory loss, because he says the effects measured in the studies are not very convincing. “I don’t think it’s the magic bullet that people are looking for,” Morrison says. When talking to his patients, he too focuses on the importance of healthy habits and good social relationships.
The study was funded, in part, by the National Institutes of Health and other grants. The vitamins were provided by Pfizer Inc. and Haleon, the makers of Centrum, the brand of multivitamins taken by participants in the study. The study authors say the funders had “no role” in the study design, analysis or interpretation.

Walking improves brain connectivity, memory in older adults, finds study
Representative Image . Image Credit: ANI A new research from the University of Maryland School of Public Health shows that walking increases connections within and between three brain networks, including one linked to Alzheimer’s disease, adding to the increasing body of data that exercise benefits brain health. Published this month in the Journal for Alzheimer’s Disease Reports, the study examined the brains and story recollection abilities of older adults with normal brain function and those diagnosed with mild cognitive impairment, which is a slight decline in mental abilities like memory, reasoning and judgment and a risk factor for Alzheimer’s.
“Historically, the brain networks we studied in this research show deterioration over time in people with mild cognitive impairment and Alzheimer’s disease,” said J. Carson Smith, a kinesiology professor with the School of Public Health and principal investigator of the study. “They become disconnected, and as a result, people lose their ability to think clearly and remember things. We’re demonstrating that exercise training strengthens these connections.” The study builds upon Smith’s previous research, which showed how walking may decrease cerebral blood flow and improve brain function in older adults with mild cognitive impairment. Thirty-three participants, who ranged between 71 and 85 years old, walked while supervised on a treadmill four days a week for 12 weeks. Before and after this exercise regimen, researchers asked participants to read a short story and then repeat it out loud with as many details as possible. Participants also underwent functional magnetic resonance imaging (fMRI) so researchers could measure changes in communication within and between the three brain networks that control cognitive function:
Default mode network – Activates when a person isn’t doing a specific task (think daydreaming about the grocery list) and is connected to the hippocampus — one of the first brain regions affected by Alzheimer’s disease. It’s also where Alzheimer’s and amyloid plaques, a prime suspect for Alzheimer’s disease found around nerve cells, show up in tests. Frontoparietal network — Regulates decisions made when a person is completing a task. It also involves memory.
Salience network — Monitors the external world and stimuli and then decides what deserves attention. It also facilitates switching between networks to optimize performance. After 12 weeks of exercise, researchers repeated the tests and saw significant improvements in participants’ story recall abilities.
“The brain activity was stronger and more synchronized, demonstrating exercise actually can induce the brain’s ability to change and adapt,” Smith said. “These results provide even more hope that exercise may be useful as a way to prevent or help stabilize people with mild cognitive impairment and maybe, over the long term, delay their conversion to Alzheimer’s dementia.” (ANI)

40 Hz vibrations reduce Alzheimer’s pathology, symptoms in mouse models
An enlarged detail from a figure in the paper highlights reductions in phosphorylated tau (magenta) in primary somatosensory cortical neurons in Tau P301S model mice treated with 40 Hz tactile stimulation (right). An image from an untreated control is on the left. Credit: Tsai Lab/MIT Picower Institute Evidence that non-invasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer’s disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends to tactile stimulation. A new study by MIT scientists shows that Alzheimer’s model mice exposed to 40 Hz vibration an hour a day for several weeks showed improved brain health and motor function compared to untreated controls.
The MIT group is not the first to show that gamma frequency tactile stimulation can affect brain activity and improve motor function , but they are the first to show that the stimulation can also reduce levels of the hallmark Alzheimer’s protein phosphorylated tau, keep neurons from dying or losing their synapse circuit connections, and reduce neural DNA damage.
“This work demonstrates a third sensory modality that we can use to increase gamma power in the brain,” said Li-Huei Tsai, corresponding author of the study, director of The Picower Institute for Learning and Memory and the Aging Brain Initiative at MIT, and Picower Professor in the Department of Brain and Cognitive Sciences (BCS).
“We are very excited to see that 40 Hz tactile stimulation benefits motor abilities, which has not been shown with the other modalities. It would be interesting to see if tactile stimulation can benefit human subjects with impairment in motor function.”
Ho-Jun Suk, Nicole Buie, Guojie Xu and Arit Banerjee are lead authors of the study in Frontiers in Aging Neuroscience and Ed Boyden, Y. Eva Tan Professor of Neurotechnology at MIT, is a co-senior author of the paper. Boyden, an affiliate member of The Picwoer Institute, is also appointed in BCS as well as the Departments of Bioengineering and Media Arts and Sciences, the McGovern Institute for Brain Research, and the K.

In a series of papers starting in 2016, a collaboration led by Tsai’s lab has demonstrated that light flickering and/or sound clicking at 40 Hz (a technology called GENUS for Gamma Entrainment Using Sensory stimuli), reduces levels of amyloid-beta and tau proteins, prevents neuron death and preserves synapses and even sustains learning and memory in a variety of Alzheimer’s disease mouse models.
Most recently in pilot clinical studies the team showed that 40 Hz light and sound stimulation was safe, successfully increased brain activity and connectivity and appeared to produce significant clinical benefits in a small cohort of human volunteers with early-stage Alzheimer’s disease.
Other groups have replicated and corroborated health benefits of 40 Hz sensory stimulation and an MIT spin-off company, Cognito Therapeutics, has launched stage III clinical trials of light and sound stimulation as an Alzheimer’s treatment.
The new study tested whether whole-body 40 Hz tactile stimulation produced meaningful benefits in two commonly used mouse models of Alzheimer’s neurodegeneration, the Tau P301S mouse, which recapitulates the disease’s tau pathology, and the CK-p25 mouse, which recapitulates the synapse loss and DNA damage seen in human disease.
The team focused its analyses in two areas of the brain: the primary somatosensory cortex (SSp), where tactile sensations are processed, and the primary motor cortex (MOp), where the brain produces movement commands for the body.
To produce the vibration stimulation, the researchers placed mouse cages over speakers playing 40 Hz sound, which vibrated the cages. Non-stimulated control mice were in cages interspersed in the same room so that all the mice heard the same 40 Hz sound. The differences measured between the stimulated and control mice were therefore made by the addition of tactile stimulation.
First the researchers confirmed that 40 Hz vibration made a difference in neural activity in the brains of healthy (i.e. non-Alzheimer’s) mice. As measured by expression of c-fos protein, activity increased two-fold in the SSp and more than 3-fold in the MOp, a statistically significant increase in the latter case.
Once the researchers knew that 40 Hz tactile stimulation could increase neural activity, they assessed the impact on disease in the two mouse models. To ensure both sexes were represented, the team used male P301S mice and female CK-p25 mice.
P301S mice stimulated for three weeks showed significant preservation of neurons compared to unstimulated controls in both brain regions. Stimulated mice also showed significant reductions in tau in the SSp by two measures, and exhibited similar trends in the MOp.
CK-p25 mice received six weeks of vibration stimulation. These mice showed higher levels of synaptic protein markers in both brain regions compared to unvibrated control mice. They also showed reduced levels of DNA damage.
Finally the team assessed the motor abilities of mice exposed to the vibration vs. not exposed. They found that both mouse models were able to stay on a rotating rod significantly longer. P301S mice also hung on to a wire mesh for significantly longer than control mice while CK-p25 mice showed a positive, though non-significant trend.
“The current study, along with our previous studies using visual or auditory GENUS demonstrates the possibility of using non-invasive sensory stimulation as a novel therapeutic strategy for ameliorating pathology and improving behavioral performance in neurodegenerative diseases,” the authors concluded.

Board-certified pathologist Dr. Ryan Cole: Spike protein in mRNA vaccines causes unusual clumping in the bloodstream
( Natural News ) Board-certified pathologist Dr. Ryan Cole talked about how the spike protein in Wuhan coronavirus (COVID-19) mRNA vaccines trigger unusual clumping in the bloodstream at a recent White Coat Summit.
“So, this is really unusual in clotting mechanisms,” Cole explained. “To see something like this and a protein that will do this in the absence of other things that are usually necessary for a clot is very unusual. And again, concerning.”
In relation to this, Dr. Resia Pretorius from South Africa showed that spike protein can cause proteins to clump together if you take platelets out of the blood.
Cole warned during his presentation that the mRNA vaccine’s spike protein is toxic , causing adverse health outcomes in the short term and also for future generation. The spike protein creates blood clots that impede the flow of blood to the heart and other organs vital to human health.
According to Cole, the mRNA vaccines caused a 200 percent hike in the rate of myocarditis. He also noted that Pfizer’s mRNA vaccine caused a 16 percent decline in fertility in rats. The pathologist shared that placentas delivered to his office contain spike proteins and are not properly sized in accordance with the age of gestation. Placenta is important in the development of the fetus during pregnancy.
The mRNA vaccines appear to have caused the placentas to calcify, likely as a result of the spike protein. Additional analysis revealed the placentas also have considerable inflammation and antibodies, essentially becoming a post-jab toxic stew that is not conducive to health or survival.
Additionally, whistleblower and renowned writer Naomi Wolf revealed that some midwives told her that the placentas of vaccinated mothers are shrunken and have a silver-gray color. These signs mean that the placentas are not big enough to sustain a normal baby. (Related: Naomi Wolf: No more normal placentas since COVID-19 vaccine rollout .)
“It’s an experiment, an emergency authorization, not approved. Humanity is the phase 3 trial . What is the risk for cancer after the shot? What is the risk of autoimmune disease after the shot? What is the risk of impairing fertility for a lifetime? We don’t know,” Cole said. “So why in the world are we really pushing forward at the pace rate we’re going without knowing these things? It’s a complete attack on science and a complete attack on us.” Spike proteins can also damage the brain
The spike proteins induced by the mRNA vaccines can also cause neurological damage . This was according to retired neurosurgeon Russell Blaylock.
“This [COVID-19] injection is an injection of artificial exosomes. The brain is one of the most complex things in the entire universe and people in the medical profession really don’t understand this injection. They don’t understand what it does to the neurological apparatus of the brain and spinal cord,” Blaylock said.
He explained that when there’s systemic inflammation or any kind of trauma occurs in the body, it produces inflammation and activation of the immune system. “This sends a signal to the brain within minutes and starts activating the microglia, which is the inflammatory, cytotoxic cell in the brain,” he said, adding that this is what would happen following the first dose of the COVID-19 injection.
As the second dose is injected months later, primed microglia become fully activated. It will then release all the toxic components.
“You get chronically activated microglia [in] overactivated state, and there’s a threefold higher inflammatory reaction than you’d normally get with microglial activation,” he said.
