Learn about brain health and nootropics to boost brain function
Exercise gives the brain a boost, and may help protect against cognitive decline, but why? Image credit: NICK VEASEY/SCIENCE PHOTO LIBRARY/Getty Images. Exercise can stimulate brain-boosting molecules when muscles are active, a new study found. By innervating muscle-tissue models, researchers found that the same…
Westend6/Getty Images We all want to age gracefully. We’ll do just about anything to do it. From eating for heart health to deciding which exercises to focus on or improving vision , most people know that maintaining many aspects of physical health is crucial…
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…
Over the years, numerous observational studies have reported a strong link between higher intakes of flavonoid-rich foods and a lower risk of chronic disease and mortality. Flavonoids, sometimes called vitamin P , are polyphenolic compounds commonly found in colorful fruits and vegetables, as well…
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…

Illinois researchers used a novel tissue model to examine the effect of nerve stimulation on muscle secretion of brain-boosting factors. The nerves, colored green, trigger the muscle to release hormones and mRNA packages that foster growth of and connection between neurons in the brain….
Researchers at Forschungszentrum Jülich have found that a high single dose of creatine can temporarily enhance cognitive functions impaired by sleep deprivation, specifically improving processing capacity and short-term memory. The study cautions against excessive creatine intake due to potential health risks, although it suggests…
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…
Researchers at Duke University Medical Center discover a mechanism to enhance the fitness of cells against aging and neurodegenerative diseases. This finding will pave the way for novel therapeutic approaches in neuroprotection against aging-related disorders and neurodegeneration. Durham, North Carolina; USA; April 30, 2024….
Graphical abstract. Credit: Immunity (2024). DOI: 10.1016/j.immuni.2024.04.006 The Wistar Institute assistant professor Filippo Veglia, Ph.D., and team, have discovered a key mechanism of how glioblastoma—a serious and often fatal brain cancer—suppresses the immune system so that the tumor can grow unimpeded by the body’s…
Researchers have discovered a brain circuit in mice that inhibits eating when nauseous, pinpointing unique amygdala nerve cells that operate differently from those activated during satiety, highlighting the complex regulation of appetite. A neural pathway suppresses appetite when experiencing nausea. Feeling full, nauseous, or…

0 Noninvasive transcranial alternating current stimulation (tACS) may lead to rapid improvement in major depressive disorder (MDD), results of a randomized, sham-controlled trial suggested. However, independent experts said more research is needed to confirm its benefit. While both the active and sham tACS groups…
Scientists are learning that ovaries aren’t just important for making babies—they also keep the heart, brain, and bones healthy. A mouse ovary treated with a high dose of anti-Mullerian hormone (AMH)—a hormone naturally produced by follicles in the ovary—shows more small, dormant follicles and…
If melatonin makes you groggy, GABA could be a good alternative. Sleep is essential to all aspects of our well-being, from our mood and brain functions to our immune system , heart health and more. Despite how important a good night’s sleep is, many…
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…
The major nodes of a human brain network that keeps us awake are shown color-coded in this MRI scan of a postmortem brain. (Image credit: Edlow et al., Sci. Trans. Med., 16 eadj4303 (2024). (Cropped by Live Science.)) Scientists have charted a comprehensive map…
The brain can direct the immune system to an unexpected degree, capable of detecting, ramping up and tamping down inflammation, shows a new study in mice from researchers at Columbia’s Zuckerman Institute. “The brain is the center of our thoughts, emotions, memories and feelings,”…
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…
