The amygdala is part of the limbic system, a neural network that mediates many aspects of emotion and memory. The amygdala is a cluster of almond-shaped cells located near the base of the brain. Emotions influence cognitive processes such as attention, memory formation, and decision making, and they play a prominent role in social behaviour. There exist a vast array of human emotions, ranging from joy to sadness, disgust to excitement, and regret to satisfaction. Amygdala dysfunction affects emotional processing, memory formation and storage, and conditional learning, and as such, it is associated with several neurodevelopmental and neurologic disorders as well as psychiatric conditions.

Most peoples triggers will fall into the same general categories (stress, anger, aggression), but each persons triggers will be unique to them. How you react depends on which system dominates the response at the time. Zaccaro A, et al. (2017).

It was first believed to function as a brain center for responding primarily to anxiety and fear. A pathway from the amygdala to the ventral striatum, which has been implicated in reward processing in addiction, mediates learned approach behaviours (movements toward objects or other individuals). Reasoning takes place in the frontal lobes. However, the frontal lobes process the information to determine if the threat is real and what a logical response would be. Following this line of thinking, Willie, post-doctoral fellow Cory Inman, and psychologist Joseph Manns wondered if they might help potentiate, or tag, certain memories in rats by stimulating the amygdala.
