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 ...

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.

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 ...

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, ...

Reaction time reflects brain processing speed; simple tests like the ruler drop can reveal attention, coordination, and early cognitive changes.

Modern neuroscience understands the brain as a set of specialized systems. Aspects of brain function such as attention, perception, memory, language, and thought have been mapped onto distinct brain ...

Researchers have identified a surprising brain pattern that may help explain why people with ADHD often struggle to stay focused. Even while awake, their brains can slip into brief episodes of ...

Cocaine addiction may persist because the drug rewires brain circuits through a protein called DeltaFosB. This buildup ...

As we age, it’s not uncommon for the brain to change in ways that can negatively impact our cognition. However, there is one population known as “SuperAgers” who are adults ages 80 and older who tend ...
