What happens to the brain during fight or flight?


What happens to the brain during fight or flight? When it appears to the amygdala there is a threat, it redirects the hypothalamus to begin producing extra cortisol and adrenaline. The sole purpose of these hormones is to motivate and produce movement in the body, shown in the response of fight or flight. Our brain's first plan for our bodies when in danger is action.
