Melanopsin activates divergent phototransduction pathways in intrinsically photosensitive retinal ganglion cell subtypes [PDF]

eLife, 2023
Melanopsin signaling within intrinsically photosensitive retinal ganglion cell (ipRGC) subtypes impacts a broad range of behaviors from circadian photoentrainment to conscious visual perception.

Long-Term Narrowband Lighting Influences Activity but Not Intrinsically Photosensitive Retinal Ganglion Cell-Driven Pupil Responses [PDF]

Frontiers in Physiology, 2021
Purpose: Light affects a variety of non-image forming processes, such as circadian rhythm entrainment and the pupillary light reflex, which are mediated by intrinsically photosensitive retinal ganglion cells (ipRGCs).

Chromatic pupillometry isolation and evaluation of intrinsically photosensitive retinal ganglion cell-driven pupillary light response in patients with retinitis pigmentosa [PDF]

Frontiers in Human Neuroscience, 2023
PurposeThe pupil light response (PLR) is driven by rods, cones, and intrinsically photosensitive retinal ganglion cells (ipRGCs). We aimed to isolate ipRGC-driven pupil responses using chromatic pupillometry and to determine the effect of advanced ...

M1 Intrinsically Photosensitive Retinal Ganglion Cells Integrate Rod and Melanopsin Inputs to Signal in Low Light

Cell Reports, 2019
Summary: Light influences various behaviors and physiological processes that occur outside of our conscious perception, including circadian photoentrainment, sleep, and even learning and mood.

Bipolar cell networks underlying steady-state intensity encoding in intrinsically photosensitive retinal ganglion cells [PDF]

iScience
Summary: Intrinsically photosensitive retinal ganglion cells (ipRGCs) encode ambient light intensity at steady-state and drive physiology even in the absence of melanopsin, but the synaptic basis of such encoding remains unclear.

Pituitary Adenylate Cyclase-Activating Peptide (PACAP)-Glutamate Co-transmission Drives Circadian Phase-Advancing Responses to Intrinsically Photosensitive Retinal Ganglion Cell Projections by Suprachiasmatic Nucleus [PDF]

Frontiers in Neuroscience, 2019
Results from a variety of sources indicate a role for pituitary adenylate cyclase-activating polypeptide (PACAP) in light/glutamate-induced phase resetting of the circadian clock mediated by the retinohypothalamic tract (RHT). Attempts to block or remove
