Selective amplification of ipRGC signals accounts for interictal photophobia in migraine [PDF]
Proceedings of the National Academy of Sciences, 2020 Abstract Second only to headache, photophobia is the most debilitating symptom reported by people with migraine. While the melanopsin-containing, intrinsically photosensitive retinal ganglion cells (ipRGCs) are thought to play a role, how cone and melanopsin signals are integrated in this pathway to produce visual discomfort is poorly ...

Intrinsically Photosensitive Retinal Ganglion Cells of the Human Retina
Frontiers in Neurology, 2021 Light profoundly affects our mental and physical health. In particular, light, when not delivered at the appropriate time, may have detrimental effects.

The retinal ipRGC-preoptic circuit mediates the acute effect of light on sleep [PDF]
Nature Communications, 2021 Abstract Light regulates daily sleep rhythms by a neural circuit that connects intrinsically photosensitive retinal ganglion cells (ipRGCs) to the circadian pacemaker, the suprachiasmatic nucleus. Light, however, also acutely affects sleep in a circadian-independent manner.

Nature Communications, 2023 In addition to rod and cone photoreceptors, the mammalian retina contains intrinsically photosensitive retinal ganglion cells (ipRGCs). Here the authors identify a population of ipRGCs that encode ventral vision.

Intrinsic photosensitive retinal ganglion cells in the diurnal rodent, Arvicanthis ansorgei.
PLoS ONE, 2013 Intrinsically photosensitive retinal ganglion cells (ipRGCs) represent a new class of photoreceptors which support a variety of non-image forming physiological functions, such as circadian photoentrainment, pupillary light reflex and masking responses to

A new method to quantify the human visual threshold from melanopsin sensitive ganglion cells
Frontiers in Cellular Neuroscience, 2023 Traditional photoreceptors utilize the chromophore retinal to absorb light coupled with a unique opsin protein to specify receptor spectral sensitivity.

Endogenous opioid signaling in the retina modulates sleep/wake activity in mice
Neurobiology of Sleep and Circadian Rhythms, 2022 Circadian sleep/wake rhythms are synchronized to environmental light/dark cycles in a process known as photoentrainment. We have previously shown that activation of β-endorphin-preferring μ-opioid receptors (MORs) inhibits the light-evoked firing of ...

Development of melanopsin-based irradiance detecting circuitry
Neural Development, 2011 Background Most retinal ganglion cells (RGCs) convey contrast and motion information to visual brain centers. Approximately 2% of RGCs are intrinsically photosensitive (ipRGCs), express melanopsin and are necessary for light to modulate specific ...
