The periamygdaloid cortex is located on the dorsal surface of the brain bordered by the piriform cortex, entorhinal cortex, perirhinal cortex, periamygdalar claustrum, and anterior amygdaloid area.[1] Its ventromedial and dorsolateral borders are defined by the first myelin bundle of the external capsule, while its remaining borders show no myelinated fiber projections or inputs as well as a higher density of acetylcholinesterase and cholinergic synapses than the neighboring anterior amygdaloid area.[2]
