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 ...

Different brain regions are connected by—and interact through—networks of neurons. But the extent to which neuronal wiring drives shared function between these different regions is not well understood ...

In a new paper with implications for preventing Alzheimer's disease and other neurological disorders, Keith Hengen, an associate professor of biology in Arts & Sciences at Washington University in St.

“A central goal of neuroscience is to develop an understanding of the brain that ultimately describes the mechanistic basis of human cognition and behavior,” said Jeremy Herskowitz, Ph.D., associate ...

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.

McGill University researchers have identified a brain function that helps explain why childhood stress raises metabolic health risks for some women later in life. A new study found that variations in ...

Alzheimer's disease is a progressive and permanent loss of nerve cells in the brain. The breakdown causes memory loss, ...

Elon Musk co-founded Neuralink in 2016 to develop brain-machine interfaces. The first product — the N1 implant — focuses on allowing patients with paralysis to control computer cursors with their mind ...

Can stress make you age before your time? Doctors reveal why grey hair in your 20s and brain fog in your 30s aren't always a ...

A long-standing goal of neuroscience is to understand how molecules and cellular structures on a microscale give rise to communication between brain regions at the macroscale. A study now identifies, ...
