Pupillometric measures of melanopsin containing retinal ganglion cell responsivity: Individual differences in responsivity and Psychopathology
The post-illumination pupil response (PIPR) indexes the responsivity of the intrinsically photosensitive retinal ganglion cells (ipRGCs) containing melanopsin. As these cells are the retinal origin of projections to the central circadian clock, individual differences in the cell biology, signal transduction, and neurotransmission of ipRGCs are relevant for sleep and circadian behavior and pathology. Current projects, new data, and the implications of this work for understanding the role of environmental light on mood and alertness are discussed.Find out more »
