The Amygdala are a cluster of nuclei in the temporal pole.
The amygdala recieves afferent fibers from the cingulate gyri, the hippocampus, and the neocortex. The amygdala recieves a seperate feed for each somatosensory input from the neocortex.
The amydala associates emotional valency with memory, including fear. Memories associated with fear will cause certain behaviors not to be done again in order to avoid further fear.
