Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

Scientists mapped how waste leaves the brain, uncovering drainage pathways that could help explain Alzheimer's disease and ...

The 'silent' X chromosome within female brains may not be so silent after all. A new study has found evidence in both mice and humans that as we age, 'sleeping' X chromosomes can be 'awakened' in ...

The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary ...

Recent work has revealed some of the many crucial functions of astrocytes, brain cells that were once thought to play primarily supportive roles for neurons. Astrocytes do handle debris around neurons ...

Parkinson's disease does more than cause tremor and trouble walking. It can also affect sleep, smell, digestion and even thinking. That may be because the disease disrupts communication in a brain ...

OK, if I say the word puppy, you probably get a mental picture of something cute and cuddly with ears and a wiggly tail. And that's because most brains can generate an internal image without any input ...

Menopause has long been treated like a reproductive footnote. Neuroscience is revealing it may be one of the most ...

Add Yahoo as a preferred source to see more of our stories on Google. Nothing’s quite as refreshing as a slushie or ice cream cone on a hot, humid day. But these frozen treats can sometimes trigger ...

Electroconvulsive therapy is highly effective in treating major depressive disorder, but no one knows why it works. New research suggests it may restore balance between excitation and inhibition in ...

Electroconvulsive therapy (ECT), formerly known as electroshock therapy, involves inducing a brief seizure in the brain using controlled doses of electricity. While ECT is highly effective for certain ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and send information and commands throughout the brain and the nervous system.
