When faced with danger, animals have to react fast. Heart rates climb, muscles tense, and the body prepares to fight or flee.

A study discovered a circuit in the brain that connects stress with increased glucose and therefore may link stress to type 2 ...

The authors then applied an innovative technique known as closed-loop stimulation to change amygdala function in the hope of reducing PTSD symptoms.

The scientists focused on the circuits in the central amygdala (CeL)—a brain region known to serve as an inhibitory gate on the downstream expression of fear responses—and found striking results.

"To analyze how the amygdala functions during depression, we measured the activity of some networks of neurons involved in the more or less negative interpretation of olfactory stimuli," says ...

Researchers have shown how the amygdala, a brain region typically associated with fear, contributes to prepulse inhibition (PPI) by activating small inhibitory neurons in the mouse brain stem. The ...

“This will allow us to probe whether amygdala function — its increased engagement, heart rate mobilization in emotionally evocative situations and its hypothesized emotion-dependent connectivity with ...
