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 ...

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.

Emerging research shows a strong link between diabetes, insulin resistance and Alzheimer's disease. Experts say glucose fluctuations may harm brain health.

Nearly 16 million American adults have been diagnosed with attention deficit hyperactivity disorder (ADHD), but evidence suggests that more than 30% of them don't respond well to stimulant medications ...

Not all brain cells are found in the brain. For example, a team at Caltech has identified two distinct types of neurons in the abdomens of mice that appear to control different aspects of digestion.
