Brain Energy Boost Mechanism Discovered
Summary: Researchers identified a key mechanism that detects when the brain needs an energy boost, involving astrocytes and the molecule adenosine. This discovery could lead to new therapies for maintaining brain health and longevity, particularly in combating cognitive decline and neurodegenerative diseases. The study…
Serotonin 2C Receptor Key to Memory
Summary: Researchers discovered the serotonin 2C receptor in the brain plays a crucial role in regulating memory in both humans and animal models. This breakthrough offers insights into conditions associated with memory loss, such as Alzheimer’s disease, and suggests new treatment pathways. Mutations in…
Scientists Identify Key Pathway for Brain Health Boost via Ketogenic Diet
The ketogenic diet improves memory in aging mice by enhancing synapse function through a newly identified molecular signaling pathway involving ketone bodies, particularly β-hydroxybutyrate (BHB). Future research seeks to replicate these benefits without the diet by targeting specific pathways. Understanding these mechanisms offers new…
How does oxygen depletion disrupt memory formation in the brain?
The aLTP process is activated when the brain is deprived of oxygen When we learn something new, our brain cells (neurons) communicate with each other through electrical and chemical signals. If the same group of neurons communicate together often, the connections between them get…
The brain can store nearly 10 times more data than previously thought, study confirms
The amount of information the brain can store is greater than once thought, new research suggests. The brain may be able to hold nearly 10 times more information than previously thought, a new study confirms. Similar to computers, the brain’s memory storage is measured…
Upgrading brain storage: Quantifying how much information our synapses can hold
Two neurons, one in full (left, light purple) and one partially out of frame (right, light blue) on top of a background of zeros and ones to symbolize the unit of bits used to quantify information storage in synapses. The neuron on the left…
Can Anxiety Relief Come at the Cost of Cognitive Health?
Key points Long-term use of benzos can lead to addiction & cognitive impairments. Older people are particularly vulnerable to the impairing effects of long-term benzodiazepine use. A recent study revealed the mechanism by which benzos interfere with plasticity and cognitive abilities. Other treatments such…
Researchers demonstrate a new mechanism of neural plasticity underlying learning and memory processes
Graphical abstract. Credit: Cell Reports (2024). DOI: 10.1016/j.celrep.2024.114112 Neurons are important, but they are not everything. Indeed, it is “cartilage,” in the form of clusters of extracellular matrix molecules called chondroitin sulfates, located in the outside nerve cells, that plays a crucial role in…
Sleep resets brain connections for a few hours, but then what happens?
In a study involving zebrafish, a team of scientists led by the University College London (UCL) has explored how the brain manages synaptic connections during sleep . The experts found that the brain weakens new neural connections that were forged during waking hours, but…
Scientists say sleep resets brain connections—but only for first few hours
Single-neuron synapse tracking across day–night cycles reveals diverse dynamics. Credit: Nature (2024). DOI: 10.1038/s41586-024-07367-3 During sleep, the brain weakens the new connections between neurons that had been forged while awake—but only during the first half of a night’s sleep, according to a new study…
Sleep resets brain connections — but only for first few hours
During sleep, the brain weakens the new connections between neurons that had been forged while awake — but only during the first half of a night’s sleep, according to a new study in fish by UCL scientists. The researchers say their findings, published in…
First experimental proof for brain-like computer with water and salt
Below shows a graphical representation of the synapse. The synapse consists of colloidal spheres with nano-channels between them.

This…
New brain-like transistor mimics human intelligence
Taking inspiration from the human brain, researchers have developed a new synaptic transistor capable of higher-level thinking. Designed by researchers at Northwestern University, Boston College and the Massachusetts Institute of Technology (MIT), the device simultaneously processes and stores information just like the human brain….
There’s a ‘Wave of Death’ in Every Human Brain. Scientists Are Scrambling to Stop It.
Working to Stave Off Brain’s ‘Wave of Death’Ioannis Tsotras – Getty Images Researchers studying the brain’s final moments have gained new insight into the “wave of death” that occurs before a brain’s activity fully flatlines. When neural activity stops, it doesn’t stop abruptly, but…
When do brains grow up? Research shows mouse and primate brains mature at same pace
Excitatory axon development in mouse and primate. a Cartoon depicting hypothetical models of excitatory axon development: left, axons increase their synapse frequency and/or right, axons make more branches. b, c Histograms of the number of synapses/µm and branches/µm, respectively, of excitatory axons at different…
Neuroscientists pinpoint how memories are likely to be stored in the brain

Neuroscientists are Tantalizingly Close to Mastering How Psychedelics Redesign Our Brains
The first-line pharmacological treatment for major depressive disorder (MDD) is antidepressant drugs known as selective serotonin reuptake inhibitors (SSRIs). However, a significant proportion of people don’t respond to these drugs. Given that major depression is a global mental health problem that is on the…
Memory Block: How Saturated Fats May Hinder Memory Formation in the Aging Brain
A new study suggests that a high-fat diet may impair memory by causing inflammatory effects and issues in cell-signaling management in the brain cells, especially as people age, but the omega-3 fatty acid DHA may help mitigate these effects. The research, focusing on microglia…
The Power Within by Corey Daniels book available for only $2.99
Mind has both conscious and subconscious halves. These are likened to a driver and the truck he drives. The driver plans the destination and observes road conditions, while the truck provides motive power. Your subconscious mind is like the truck and it only goes in the direction in which is a steered. This can be the road or off a cliff. Likewise, the consciousness paints a picture of what the world is and what your goals are and the subconscious acts on them through emotion, physical response and energy, whether these are correct, rational images or false negative ones. The subconscious is also like an emotional reservoir which your body and mind draw responses from to external stimuli.
The Power Within lays out a method of programming your subconscious and tapping into the Holy Spirit, God voice or what the Greeks called the daimon (godman).
