Summary: Scientists have identified how depression alters the brain’s response to positive and negative stimuli, particularly in the amygdala, a key emotional processing center. The study found that ...

"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 Alonso.

The work is published Oct. 30 in the American Journal of Psychiatry. "The amygdala is central to emotion processing in the brain, and is known to contribute to fear and anxiety," said Drew Fox ...

This finding supports the idea that multiple functional neural subpopulations may be present within the GABAergic PPN population ... For example, PPN neurons that excite amygdala nuclei evoke place ...
