Memory is not a recording device. It doesn't play back events like a video camera would. Instead, it's a remarkably active, ...

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, ...

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 ...

Fear response to traumatic or threatening situations helps us evade or escape danger. At the same time fear response is learned in the form of association between stimulus or situation and the ...

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

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

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

A team of researchers has shown that noninvasive electrical stimulation of the vagus nerve through the ear can reverse memory deficits caused by acute stress in mice, pinpointing a specific protein ...

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