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.
Picture above obtained from [ref1] The amygdala of the human brain is placed somewhat strategically at dorsomedial part (above and inside) of temporal lobe, anteriorly (in front) of the hippocampus and close to the tail of the caudate nucleus. It is placed quite near to the the hypothalamus and also the brainstem. Picture below shows the diagrammatic representation of amygdalaâs location and structure. (image obtained from [ref2]). This almond like structure, ranging from 1-4cm , average about 1.8cm, has extensive connection with the brain.
