Photoreceptive areas responsible for the regulation of photoperiodicity have been localized in the brain of some avian species. We found that immunoreactivities to rhodopsin and the α-subunit of rod-type transducin (Gt1α) were colocalized in cerebrospinal fluid (CSF) contacting neurons in the pigeon lateral septum, a possible site for photoreception. Furthermore, RT-PCR analyses showed specific gene expression of both cGMP-phosphodiesterase β-subunit and cone-type cGMP-gated cation channel α-subunit in this region. These results suggest that several components in rod/cone photoreceptors compositely contribute to the deep encephalic phototransduction cascade. (C) 2000 Wiley-Liss, Inc.
