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 is an important structure located in the anterior temporal lobe within the uncus. The amygdala makes reciprocal connections with many brain regions (figure 32) including the thalamus, hypothalamus, septal nuclei, orbital frontal cortex, cingulate gyrus, hippocampus, parahippocampal gyrus, and brain stem.lfactory signals are relayed to several other brain regions after their initial termination in the olfactory cortex. The olfactory cortex affects the frontal lobe through connections with the dorsomedial nucleus of the thalamus.
