Neuronal morphology in the bed nucleus of the stria terminalis (BST) was studied using Golgi techniques. The principal neurons of the lateral subdivision of BST have ovoid perikarya and 4-5 dendrites that branch several times and exhibit a dense covering of spines. Adjacent to the internal capsule is a small region, termed the "juxtacapsular subdivision" of BST, that consists of small, spiny cells. Neurons of the medial subdivision of BST have ovoid perikarya and 2-3 dendrites that branch sparingly. Dendritic spine density varies from sparse to moderate. Dendrites in the dorsocaudal portion of the medial subdivision extend into a cell-sparse zone adjacent to the lateral ventricle. Cells in the lateral portion of the preoptic continuation of BST have dendrites oriented perpendicular to fibers of the stria terminalis which traverse this area while medially located cells are oriented parallel to fibers of the stria. Axons of BST neurons emit collaterals that arborize modestly near the cell of origin. Neurons in the lateral and medial subdivisions of BST resemble, respectively, cells in the lateral and medial subdivisions of the central amygdaloid nucleus. Neurons in the juxtacapsular subdivision of BST are similar to neurons of the intercalated masses of the amygdala.
运用高尔基染色技术研究终纹床核（BST）的神经元形态。BST外侧亚区的主要神经元具有卵圆形的胞体和4 - 5条树突，这些树突多次分支并呈现出密集的棘突覆盖。与内囊相邻的是一个小区域，称为BST的“囊旁亚区”，由小的、有棘突的细胞组成。BST内侧亚区的神经元具有卵圆形的胞体和2 - 3条分支较少的树突。树突棘密度从稀疏到中等不等。内侧亚区背尾部分的树突延伸到与侧脑室相邻的细胞稀疏区。BST视前延续部外侧部分的细胞具有垂直于穿过该区域的终纹纤维定向的树突，而位于内侧的细胞则与终纹纤维平行定向。BST神经元的轴突发出侧支，在起源细胞附近适度分支。BST外侧和内侧亚区的神经元分别类似于中央杏仁核外侧和内侧亚区的细胞。BST囊旁亚区的神经元类似于杏仁核插入团的神经元。
