Mice that were repeatedly exposed to an aggressive intruder had a hard time recalling where the escape hole was in a maze they’d mastered prior to the stressful period. They also had measurable changes in their brains, including evidence of inflammation brought on by the immune system’s response to the outside pressure. This was associated with the presence of immune cells, called macrophages, in the brain of the stressed m...
