Neurobiologists at UC San Diego find stress triggers general fear responses in the dorsal raphe, potentially informing PTSD interventions.
Neurobiologists at the University of California San Diego have identified changes in brain biochemistry and neural circuitry that cause generalized fear experiences, even in the absence of real threats. The research reveals that acute stress triggers a switch in the chemical signals of neurons in the dorsal raphe, leading to generalized fear responses. This discovery could provide insights into interventions for conditions such as PTSD.
