Mice Exposed To Chronic Stress Have Worse Memory; Blame It On The Immune System?

New research on mice further adds support to the link between chronic stress and memory impairment, as well as suggests a possible culprit for the connection — our very own immune system. The study, published Tuesday in The Journal of Neuroscience, examined how well a group of mice performed on a memory task (finding the escape hole out of a maze) before and after they had been repeatedly exposed to a larger bully mouse. When compared to a control group of mice mercifully left alone, the bullied mice proved less able to remember the way out. “The stressed mice didn’t recall it,” said lead author Jonathan Godbout, associate professor of neuroscience at Ohio State University, in a statement. “The mice that weren’t stressed, they really remembered it.” In humans, it’s…
