Contributions of the inner retinal photopigment melanopsin to human visual perception are
incompletely understood. Here, we use a four-primary display to produce stimuli differing in …

Melanopsin photoreception enhances retinal responses to variations in ambient light
(irradiance) and drives non-image-forming visual reflexes such as circadian entrainment [1 …

The photopigment melanopsin supports reflexive visual functions in people, such as pupil
constriction and circadian photoentrainment. What contribution melanopsin makes to …

The visual consequences of melanopsin photoreception in humans are not well understood.
Here we studied melanopsin photoreception using a technique of photoreceptor silent …

Melanopsin is a short-wavelength-sensitive photopigment that was discovered only around
20 years ago. It is expressed in the cell bodies and processes of a subset of retinal ganglion …

Detection and discrimination of spatial patterns is thought to originate with photoreception by
rods and cones. Here, we investigated whether the inner-retinal photoreceptor melanopsin …

Following photopigment bleaching, the rhodopsin and cone-opsins show a characteristic
exponential regeneration in the dark with a photocycle dependent on the retinal pigment …

To evaluate the nature of interactions between visual pathways transmitting the slower
melanopsin and faster rod and cone signals, we implement a temporal phase summation …

Photoreception in the mammalian retina is not restricted to rods and cones but extends to a
small number of intrinsically photoreceptive retinal ganglion cells (ipRGCs), expressing the …

A small fraction of mammalian retinal ganglion cells are directly photoreceptive thanks to
their expression of the photopigment melanopsin. These intrinsically photosensitive retinal …
