Bed Nucleus Of The Stria Terminalis Lateral Subdivision

Abbreviation

Description of part
The lateral division of the bed nucleus of the stria terminalis (BSTL) is in the general form of an irregular truncated pyramid with its base apposed to the medial side of the internal capsule, which forms its medial boundary (Figs 4A; SA, B, C; 6A, B, C; 7F). Rostrally, it adjoins the posterior aspect of the nucleus accumbens ventrally and the caudate-putamen dorsally. The medial boundary of the BSTL is marked by the compact fibers of the stria terminalis. It rests atop the anterior commissure and extends slightly rostral along its anterior limb. Caudally, it dips ventrally to surround the posterior face of tpe posterior limb of the anterior commissure. Moving from rostrodorsal to caudoventral, the BSTL tapers somewhat until it fuses with the rostromedial end of the SLSI. In general, cells in the BSTL are somewhat larger and more loosely packed than those in the BSTM. Based on cytoarchitecture and histochemical criteria, the BSTL can be divided into four subdivisions: juxtacapsular, dorsal, ventral and posterior.
