Abstract: HighlightsThis model introduces Beer‐Lambert optical law to a phototransduction model.A limited amount of rhodopsin allows for an exponential decrease response.Rhodopsin concentration varies in relation to the previous stimulus.This model improves responses to light‐adapted conditions.This model… read more here.

DOI: 10.1073/pnas.2216599120
Abstract: Nonimage-forming vision in mammals is mediated primarily by melanopsin (OPN4)-expressing, intrinsically photosensitive retinal ganglion cells (ipRGCs). In mouse M1-ipRGCs, melanopsin predominantly activates, via Gαq,11,14, phospholipase C-β4 to open transient receptor 6 (TRPC6) and TRPC7 channels.… read more here.

DOI: 10.1098/rsob.170232
Abstract: Different isoforms of the genes involved in phototransduction are expressed in vertebrate rod and cone photoreceptors, providing a unique example of parallel evolution via gene duplication. In this study, we determine the molecular phylogeny of… read more here.

DOI: 10.1371/journal.pbio.3000750
Abstract: Photoreceptors are specialized cells devoted to the transduction of the incoming visual signals. Rods are able also to shed from their tip old disks and to synthesize at the base of the outer segment (OS)… read more here.
