regulation of membrane potential in photoreceptor cell
http://purl.obolibrary.org/obo/GO_0016057
Hyperpolarization (vertebrates) or depolarization (invertebrates) of the photoreceptor cell membrane via closing/opening of cation specific channels as a result of signals generated by rhodopsin activation by a photon. [ GOC:tb GOC:hb GOC:dph ]
Synonyms: changes in polarization state of photoreceptor cell membrane
