Melanopsin phototransduction: slowly emerging from the dark.
Melanopsin expressing retinal ganglion cells represent a third class of ocular photoreceptors and are involved in irradiance detection and non-image-forming responses to light including pupil constriction, circadian entrainment, and regulation of sleep. Over recent years, there has been a rapid increase in our understanding of the anatomical variety of pRGC subtypes, the regions of the brain which they innervate, and the behavioral responses of melanopsin-based light detection. However, by co...Expand abstract
