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

Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, ...

A new study reveals that astrocytes, once dismissed as mere support cells, play a central role in fear memory.

A Dartmouth study challenges the conventional view that the amygdala-the two-sided structure deep in the brain involved in emotion, learning, and decision making-is simply the brain's primitive "fear ...

Neurodegenerative disease profoundly affects structures and pathways responsible for memory, cognition, and higher-order ...

The brain’s primitive “fear center” may be much more than that, as new research on the amygdala suggests it plays a crucial role in learning, emotion, and decision-making. Researchers from Dartmouth ...

I’ve been studying the amygdala for more than 30 years. When I started this work, research on this brain region was a lonely field of inquiry. The hippocampus was all the rage, and I sometimes felt ...
