Abstract:
Based on recent cellular architectural studies on the bed nuclei of the stria terminalis (BST) in the rat by Ju et al, we studied vasoactive intestinal polypeptidelike immunoreactivity (VIP-LI) in the BST using PAP and ABC techniques. (1) Compared with VIP-LI cells, the VIP-LI terminals were more abundant and concentrated. At the periphery of the oval nucleus and in the juxtacapsular nucleus, there was a dense accumulation of VIP-LI terminals. Less densely innervated areas were the part above the anterior commissure in the anterior lateral area and the central part of oval nucleus. The fusiform nucleus and rostral part of the anterior ventral area contained moderate amount of VIP-LI terminals. The principal nucleus, interfasicular nucleus, posterior dorsal nucleus and dorsal nucleus, were devoid of VIP immunoreactivity. VIP-LI fiber branches were sometimes seen going along the vessels in the BST. (2) VIP-LI cells were usually distributed in areas where the terminals were relatively sparse. In the central part of the oval nucleus, the VIP-LI cells were most concentrated, though the total number of it was less than that in the caudal part of the anterior dosal area, They were usually small fusiform in shape, however some were trangular or multipolar.
