One long-standing idea is that the amygdala consists of an evolutionarily primitive division associated with the olfactory system (cortical, medial and central nuclei) and an evolutionarily newer division associated with the neocortex (lateral, basal, and accessory basal nuclei).tructural and/or functional changes in the amygdala are associated with a wide variety of psychiatric conditions in humans. Included are various anxiety disorders (PTSD, phobia, and panic), depression, schizophrenia, and autism, to name a few.
The amygdala, part of the limbic system, is responsible for fear and other emotional reactions. It communicates with the hypothalamus to initiate the fight-or-flight response, which produces the release of epinephrine, increasing the body's heart rate and blood pressure. The physical symptoms seen in people with panic attacks evolve from the sympathetic nervous system which kicks into overdrive.
