The amygdala is a region of the brain primarily associated with emotional processes. The name amygdala is derived from the Greek word amygdale, meaning "almond," owing to the structure's almondlike shape. The amygdala is located in the medial temporal lobe, in front of the hippocampus. The amygdala is part of the limbic system, a neural network that mediates many aspects of emotion and memory. Although the amygdala was considered to be involved primarily in fear and other emotions related to unpleasant stimuli, it is now known to be involved in positive emotions elicited by rewarding stimuli.
