The amygdala is an almond-shaped brain structure which is part of the basolateral circuit of the limbic system. It is located in the temporal lobe. It appears to be a very primitive part of the brain.

The amygdala can take control of your entire brain in an emergency.

Role of The Amygdala

The amygdala generates fear and aggression and has been proven to store memories which relate to fear in rats. An experiment has been performed where the memory of a loud, frightening sound was destroyed in rats by destroying the neurons which encoded the memory.


PSTD or post-traumatic stress disorder may be the result of fear-based memories stored in the amygdala.
