High BMI Linked to Weak Smell-Eating Circuit in Brain

Summary: A new study reveals a novel brain circuit linking the sense of smell and eating behavior. The weaker the connection between these regions, the higher a person’s Body Mass Index (BMI). This discovery suggests a potential neural mechanism underlying overeating, where disrupted circuits…

An astrocytic pH regulator that can repair the blood-brain barrier and reverse brain damage caused by ischemic stroke

Ischemic stroke is a leading cause of death and disability, affecting about 15 million worldwide each year. Among the various factors contributing to the pathogenesis of this condition is the loss of the blood-brain barrier, a highly selective protective cellular barrier that prevents harmful…

Exercise stimulates brain function thanks to its effect on muscles, study suggests

Exercise stimulates brain function thanks to its effect on muscles, study suggests

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…

Study suggests eating these superfoods can help you live longer

Study suggests eating these superfoods can help you live longer

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…

Brain rhythms: Key to understanding emergent thought

Brain rhythms: Key to understanding emergent thought

Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level. It could be very informative to observe the…

Team demonstrates miniature brain stimulator in humans

Rice University engineers have developed the smallest implantable brain stimulator demonstrated in a human patient. Thanks to pioneering magnetoelectric power transfer technology, the pea-sized device developed in the Rice lab of Jacob Robinson in collaboration with Motif Neurotech and clinicians Dr. Sameer Sheth and…

Salk scientists explain how CBN protects the brain against aging and neurodegeneration

One in every 10 individuals above the age of 65 develops an age-related neurological disorder like Alzheimer’s or Parkinson’s, yet treatment options remain sparse for this population. Scientists have begun exploring whether cannabinoids-;compounds derived from the cannabis plant, like well-known THC (tetrahydrocannabinol) and CBD…
