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 ...

The brain is our body’s command center, the control tower for our body and mind—no wonder it’s the focus of intense research across the globe, with so much interest in figuring out the mysteries of ...

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.

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.

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, ...

A person in a coma is deeply unconscious, but their brain is still functioning to some degree. Brain death, however, means the permanent and irreversible loss of all brain and brainstem functions.
