Description of part

Between the lateral subdivision and the internal capsule is a small region that may be termed the ‘*juxtacapsular subdivision” of the BST (Fig. 1). This subdivision consists of neurons with small, ovoid perikarya (9-13 micrometers in diameter) and several thin dendrites that give rise to numerous, wavy branches (Fig. 2, cell C). Dendritic branches, which have a dense covering of spines, are restricted to the confines of this small region (Fig. 2). Axons originate from the perikaryon or the proximal portion of a primary dendrite but can only be followed for a short distance before they leave the section or cease to impregnate. They usually emit one or more thin, beaded collaterals that appear to remain confined to the subdivision. Additional small, spiny neurons, very similar to those of the juxtacapsular subdivision, are seen adjacent to the compact, undivided portion of the stria terminalis located between the internal capsule and lateral ventricle (Fig. 3). Similar cells are also observed encapsulating the commissural bundle of the stria during its ventromedial descent towards the anterior commissure.
