UW neuroscientists describe brain chemicals that create PTSD response

Nov. 9, 2015 Diagram of the rat brain (left) showing the outlines of various brain structures. The black rectangle is located around the basolateral amygdala (BLA), which is an important brain nucleus mediating fear responses. Panel A shows that the two proteins (in red and green) that were found to mediate the post-traumatic stress disorder (PTSD)-like behavioral abnormalities are located on membranes of the same cells. Panel B shows which specific type of cell contains these proteins. A new study by University of Wisconsin-Madison neuroscientists shows how stress chemicals reshape the brains of rodents, research that could lead to better treatments for people with post-traumatic stress disorder (PTSD). Long after traumatic events such as war, abuse and car accidents, the brains of people with PTSD overreact to loud noises and…
