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.

The 'silent' X chromosome within female brains may not be so silent after all. A new study has found evidence in both mice and humans that as we age, 'sleeping' X chromosomes can be 'awakened' 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 ...

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 central goal of ...

This is a summary of a story published by the Duke School of Medicine. Duke researcher Debra Silver is convinced that to get meaningful answers about the brain, she needs to come at it in three ...

Why does the brain remember some images and not others? One of the fundamental questions of neuroscience is how perception impacts what we remember. Yale University researchers have published a new ...

Sometimes a gentle touch feels sharp and distinct, other times it fades into the background. This inconsistency isn’t just mood—it’s biology. Scientists found that the thalamus doesn’t just relay ...

CAMBRIDGE, MA -- 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 ...

“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 ...
