Scientists have known for more than a century that a single-celled organism with no nerve cells—much less a brain—can behave in ways that resemble learning. But those observations only went so far.

Treating brain diseases is extraordinarily challenging, because drugs often work poorly and implants require risky surgery that can jeopardize critical brain functions. A group at MIT has sought a ...

The human brain contains roughly 86 billion neurons, and for decades scientists have assumed that these cells are the primary ...

The tiny chips hitch a ride on immune cells to target inflammation in the brain. Scientists hope to kick off clinical trials within three years. From restoring movement and speech in people with ...

Whether or not we grow new brain cells as adults has been the subject of an ongoing and often contentious debate. Now, evidence suggests that we can. This could help answer one of neuroscience’s most ...

Cells long thought to play a secondary role in brain function build their own far-reaching connections, according to a new study in mice. These pathways appear to connect distant regions in ways that ...

Anxiety disorders are some of the most common mental health conditions in America, affecting about one in five people nationwide. But much remains unknown about the roots of anxiety in the brain. Now, ...

University of Oregon neuroscientists have identified a group of brain cells that essentially act as a "disappointment meter," ...

For decades, textbooks told students the human brain contained 100 billion neurons. That figure, repeated so often it became ...
