Abstract

The topographical distribution of calcitonin gene-related peptide (CGRP)containing neuronal elements in the posterior hypothalamus has been re- examined by means of indirect labeled immunohistochemistry in the rat. In contrast to previous findings, no CGRP-like immunoreactive neuronal perikarya were present in the premamillary nuclei, but they form a small group of cells, which is identical to the recently described terete nucleus. In coronal sections, this small and rounded cluster of intermingled CGRP- immunopositive perikarya and fibers is situated in the lateral hypothalamus at the premamillary level, ventrolateral to the fornix. Perikarya, dendrites, presynaptic terminals, as well as nonmyelinated and some myelinated axons were labeled by CGRP-like immunoreactive material within and in the immediate vicinity of the terete nucleus. On some of the CGRP-positive neurons, neuropeptide Y-immunoreactive axon terminals establish synaptic contacts.
