Chronic Stress Produces Behavioral Change by Stimulating a Newly Identifed Neuron Population

It’s clear that chronic stress can impact our behavior, leading to problems like depression, reduced interest in things that previously brought us pleasure, even PTSD. Now scientists have evidence that a group of neurons in a bow-shaped portion of the brain become hyperactive after chronic exposure to stress.
