Neural circuit that drives physical responses to emotional stress discovered

Researchers have identified a brain circuit that drives physical response to emotional stress. The circuit begins in the dorsal peduncular cortex and dorsal tenia tecta, before sending signals to the hypothalamus. The findings could help with the development of treatments for panic disorders and PTSD. Read More
