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

Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to ...

A new study shows macaque species with more tolerant social systems have larger brain regions linked to emotions and social signals.

Here's how the amygdala processes fear and why it plays a key role in phobias. This is how the brain detects threats and triggers emotional fear responses.

The brain can trigger memories without conscious awareness. Unconscious memory, priming, and brain regions like the hippocampus and amygdala influence behaviour and emotions.

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 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 ...

Macaque species with higher social tolerance possess larger amygdalae, redefining the brain region as a social hub.

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 ...

Forget crowd sizes — a new study confirms that conservatives boast slightly larger amygdalas, the part of the brain that plays a key role in identifying and reacting to potential threats, compared ...

The finding reframes a brain region long tied to aggression as a core component of how primates manage complex social relationships.
