Extrahypothalamic distribution of vasotocin-immunoreactive fibers and perikarya in the avian central nervous system.

Abstract

Immunohistochemical analysis of the extrahypothalamic distribution of vasotocin-like immunoreactive elements within the central nervous system of the domestic fowl and Japanese quail, revealed several mesencephalic, pontine and bulbar target areas topographically identifiable. Extrahypothalamic immunopositive perikarya were observed in diencephalic and mesencephalic locations after glutaraldehyde fixation.
