Fig. 1. A, Nissl-stained sections through the ventral striatum. White arrowheads indicate the location of granule cell clusters. C, Core;DBB, diagonal band of Broca; ICM, island of Calleja magna; S, shell; V, ventricle.B–E, Ventral striatum stained for CaBP (B), SP (C), TH (D), and AChE (E).Arrowheads in B and Dindicate the transition between shell and core. White arrows show the island of Calleja magna.Asterisk shows triangular zone at tip of dorsomedial shell that is high in CaBP and low in TH–SP–AChE. F, Nissl-stained sections through the amygdalostriatal area and caudoventral striatum. Fibers of the stria terminalis (ST) divide the central amygdaloid nucleus (CeN) and amygdalostriatal area (Astr). BLA, Basolateral nucleus of the amygdala; C/Pu, caudate-putamen; H, hippocampus; ST, stria terminalis. G–J, The amygdalostriatal area–caudoventral striatum stained for CaBP (G), SP (H), TH (I), and AChE (J).Arrowheads in G and Hindicate the transition between shell and core. CeLcn, Lateral core, central nucleus; G, globus pallidus;ST, stria terminalis. K,L, Bcl-2 immunoreactivity in the ventral striatum (K, k′, k") and caudal amygdala and amygdalostriatal area (L,l′, l"). Scale bars, 50 μm.M, Components of the rostral and caudal ventral striatum.
