Description of part

The intermediate part of the lateral bed nucleus of the stria terminalis is composed of predominantly angular dark-staining large (15-20 micrometers) neurons (the largest of all neurons in the bed nucleus of the stria terminalis), which are interposed berween the remaining divisions of the lateral bed nucleus of the stria terminalis and the posterior medial bed nucleus. The cells form a narrow wedge in sagittal sections, but appear similar to a flattened crescent in horizontal sections (Figs. 28a, 28E, and 32). The long axes of these cells are oriented in an oblique angle, which is parallel to fibers traversing the intermediate bed nucleus in a lateroventral to mediodorsal direction. The intermediate bed nucleus of the stria terminalis extends dorsally until it reaches the dark-staining cell groups that accompany the commissural component of the stria terminalis (that is, the bed nucleus of the commissural component of the stria terminalis). Ventrally, the intermediate bed nucleus merges with the lateral preoptic area, whereas, laterally, it merges with the sublenticular extended amygdala.
