AVP receptors in the pontine nuclei (Pn).V1aR and V1bR were expressed in a similar matter in Pn except for transverse fibers pons (tfp) (Fig. 10a and b). a The V1aR immunoreactivity showed an almost background like pattern, yet, neurons within Pn showed intense immunoreactivity in the neuronal cytoplasm. b The neurons expressed intense immunoreactivity in the cytoplasm, as did in V1aR immunohistochemistry. V1aR and V1bR were expressed in a similar matter in Pn except for transverse fibers pons (tfp) (arrows) that were observed in V1aR staining (a), but not in V1bR (b). The longitudinal fasciculus of the pons (lfp) did not show any expression of the two receptors
