Abstract:
:The distribution of VIP-like perikarya and fibers was determined throughout the chick brain. The most rostral immunoreactive perikarya were found to be cerebrospinal fluid-contacting neurons in the pars medialis of the lateral septal organ. Additional data were presented supporting the idea that the lateral septal organ is another circumventricular organ within the brain of birds (Kuenzel and van Tienhoven 1982). A large group of immunoreactive perikarya was found in the lateral hypothalamic area and appeared continuous with immunoreactive neurons in the anterior medial and ventromedial hypothalamic nuclei (n). A few perikarya were located in the paraventricular hypothalamic n. A number of immunoreactive neurons were found within and about the infundibular and inferior hypothalamic n., none however was immunoreactive cerebrospinal fluid-contacting neurons. Immunoreactive perikarya were found predominantly in laminae 10-11 of the stratum griseum et fibrosum superficiale. A few scattered perikarya were found ventromedial to the n. tegmenti pedunculo-pontinus pars compacta and locus ceruleus. Some of the immunoreactivity was unusual, being very homogeneous within the cell body with little evidence of the material in the axon or dendrites. Perikarya were found in the central gray, n. intercollicularis, and area ventralis of Tsai. The most caudal structure showing immunoreactive neurons was the n. reticularis paragigantocellularis lateralis. Brain areas containing the most abundant immunoreactive fibers, listed from the rostral-most location, were found in the ventromedial region of the lobus parolfactorius and the lateral septal n. Continuing caudally, there were immunoreactive fibers within the periventricular hypothalamic n.; some of the fibers were found to travel for some distance parallel to the third ventricle. Dense immunoreactive fibers were found in the tractus cortico-habenularis et cortico-septalis, medial habenular n. and posterior and dorsal n. of the archistriatum. A number of areas had what appeared to be baskets of immunoreactive fibers (perhaps immunoreactive terminals) surrounding non-reactive perikarya. Brain areas containing terminals included the piriform cortex, area ventralis of Tsai, interpeduncular n., and specific regions of the stratum griseum et fibrosum superficiale. A very dense immunoreactivity occurred within the external zone of the median eminence, the dorsolateral parabrachial n., and n. tractus solitarii. Vasoactive intestinal polypeptide appears to be a useful peptide for defining the neuroanatomical constituents of the visceral forebrain in birds.
