For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system?

A new study has found that SuperAgers also grow more neurons than other older adults groups, helping to keep their brains healthy. As we age, it’s not uncommon for the brain to change in ways that can ...

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 ...

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.

At this razor's edge, brains are primed to gain new information, Hengen said. "Brains need to reach criticality to think, remember and learn." Hengen proposed criticality as a unifying theory of brain ...

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, ...

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 ...

“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 ...

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 ...
