Vasotocin fibers and neurons in the brain of the domestic fowl (Gallus gallus domesticus).
Vasotocin fibers (VIFs) and neurons (VINs) in the brain stem of the domestic fowl (Gallus gallus domesticus) were described using an immunohistochemical technique. Attention was especially focused on the VIF network. VIFs were seen in the preoptic area around the septomesecephalic tract, periventricular nuclei of the hypothalamus, the lateral geniculate nucleus, the superficial synencephalic nucleus, the triangular nucleus, the ovoidal nucleus, the ectomammillary nucleus, the superficial layer (IIa-d) of the tectum, the locus ceruleus, the caudal lineal nucleus, the descending nucleus of the trigeminal nerve and the nucleus of raphe. VIFs in the retinorecipient nuclei such as the lateral geniculate nucleus and tectum indicated the possibility of interplay between the visual and the vasotocinergic nervous systems. Moreover, VIFs in the non-retinorecipient nuclei mentioned above suggested that the vasotocinergic nervous system was related not only to the visual but also to other functions, such as the autonomic and sensory nervous systems. VINs were found in the preoptic area, the lateral and the medial hypothalamus, including the nucleus periventricularis magnocelullaris, and the dorsolateral thalamus. The dorsolateral thalamic VINs were found lateral and dorsal to the lateral forebrain bundle, lateral to the nucleus periventricularis magnocellullaris, and around the nucleus rotundus.
