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 and hippocampus are two parts of the limbic system of the brain. Both of these parts have primary functions that relate to memories and reactions to emotional aspects. These two parts, as part of the limbic system as a whole, deal with how the human brain processes these emotions and memories.he amygdala and hippocampus rely on each other to form their individual functions. Responses to stimuli are regulated by the amygdala and those responses are then used by the hippocampus in the formation of both short-term and long-term memories.
