Nuno Sousa and his colleagues at the University of Minho in Portugal found that rats that were chronically stressed engaged in rote responses, such as compulsively pressing a bar for food they had no intention of eating. The researchers discovered that the regions of the brain associated with conscious decision-making and goal-directed behaviours had shrivelled, while brain sectors associated with habit-formation thrived.

In other words, the study indicated that chronic stress puts the brain into a sort of auto-pilot mode, detaching the conscious and letting habitual and repetitive behaviours take care of everything as a coping mechanism.
