The amygdala (/əˈmɪɡdələ/; pl.: amygdalae/əˈmɪɡdəli,-laɪ/ or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil'[1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates. It is considered part of the limbic system.[2] In primates, it is located medially within the temporal lobes.[3] It consists of many nuclei, each made up of further subnuclei. The subdivision most commonly made is into the basolateral, central, cortical, and medial nuclei together with the intercalated cell clusters.[4] The amygdala has a primary role in the processing of memory, decision-making, and emotional responses (including fear, anxiety, and aggression). The amygdala was first identified and named by Karl Friedrich Burdach in 1822.[5]
