“In the study, we showed that PACAP neurons in the lateral parabrachial nucleus extensively receive inhibitory input from the central nucleus of the amygdala,” said Han. “So, our next question ...

PACAP is a neuropeptide involved in stress regulation, and the authors studied neurons in a part of the brain called the parabrachial nucleus that produce PACAP and project to the dorsal raphe ...

The study found that a brain region called the lateral parabrachial nucleus (LPBN) plays a key role in managing this heightened sensitivity. When the researchers activated LPBN neurons ...
