The amygdala is your natural alarm system. When you experience something disturbing, this primitive part of your brain sends a signal that causes a fear response. Your alarm goes off at the right time and for the right reason, to keep you safe. Those with PTSD tend to have an overactive fight or flight response. The amygdala is an animalistic part of the brain that is wired for survival. When it’s overactive, it’s hard to think rationally.

The prefrontal cortex is your brake system. It helps you think and make decisions. This rational part of the brain puts on the “brakes” when you realize that something you feared wasn’t actually a threat after all. Your prefrontal cortex regulates emotional responses triggered by the amygdala. With PTSD, there is disregulation and the prefrontal cortex is underactive.
