AChE stained sections show the various amygdaloid nuclei at four rostrocaudal levels. The section in (A) is the most rostral. AAA, anterior amygdaloid area; AC, anterior commissure; Abmc, accessory basal nucleus, magnocellular subdivision; Abpc, accessory basal nucleus, parvicellular subdivision; Abvm, accessory basal nucleus, ventromedial; ACA, amygdaloclaustral area; AHA, amygdalohippocampal area; Astr, amygdalostriatal area; Bi, basal nucleus, intermediate subdivision; Bmc, basal nucleus, magnocellular subdivision; Bpc, basal nucleus, parvicellular subdivision; CeL, Central nucleus, lateral core subdivision; CeM, central nucleus, medial subdivision; Cl, claustrum; CoA, cortical nucleus, anterior subdivision; CoP, cortical nucleus, posterior subdivision; L, lateral nucleus; M, medial nucleus; PAC, periamygdaloid cortex; Str, striatum; V, ventricle.
