A Dartmouth study challenges the conventional view that the amygdala—the two-sided structure deep in the brain involved in ...

As we work on overcoming what scares us, a new plasticity becomes available in our brain, and fear strikes out.

Researchers find that the amygdala is a sophisticated mediator that chooses between action-based and stimulus-based learning strategies under uncertainty.

"I am often said to have identified the amygdala as the brain's 'fear' center. But the fact is, I have not done this, nor has anyone else." —Joseph LeDoux (2015) 3D illustration of both amygdala.

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte ...

A new study shows that a lack of dietary fiber leads to rapid inflammation in the aging brain's amygdala, impairing emotional memory.

Astrocytes are the most common type of cell in the brain and are generally understood to help connect neurons together across the nervous system. The study shows they play a key role in learning and ...

Fear memory encoding, the process responsible for persistent reactions to trauma-associated cues, is influenced by a sparse but potent population of inhibitory cells called parvalbumin-interneurons ...

Treating anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional reactions, especially fear. But a deep understanding of this structure ...
