Melanopsin: an exciting photopigment
Trends in Neurosciences, 2008 The discovery that mice lacking rods and cones are capable of regulating their circadian rhythms by light provided the conceptual framework for the discovery of an entirely new photoreceptor system within the mammalian eye. We now know that a small subset of retinal ganglion cells are directly photosensitive and utilize an opsin/vitamin A-based ...

Characterizing the Human Cone Photoreceptor Mosaic via Dynamic Photopigment Densitometry.
PLoS ONE, 2015 Densitometry is a powerful tool for the biophysical assessment of the retina. Until recently, this was restricted to bulk spatial scales in living humans.

, 2003 Isolated organs and cell lines from zebrafish exhibit circadian oscillations in clock gene expression that can be entrained to a 24-h light/dark cycle. The mechanism underlying this cellular photosensitivity is unknown.

Frontiers in Neuroanatomy, 2022 Despite concern over potential retinal damage linked to exposure to light-emitting-diode (LED) light (particularly blue light), it remains unknown how exposure to low-intensity monochromatic LED light affects the expression of rhodopsin (Rho, a ...

Diversity of color vision: not all Australian marsupials are trichromatic. [PDF]
PLoS ONE, 2010 Color vision in marsupials has recently emerged as a particularly interesting case among mammals. It appears that there are both dichromats and trichromats among closely related species.

Melanopsin bistability: a fly's eye technology in the human retina.
PLoS ONE, 2009 In addition to rods and cones, the human retina contains light-sensitive ganglion cells that express melanopsin, a photopigment with signal transduction mechanisms similar to that of invertebrate rhabdomeric photopigments (IRP).

Melanopsin expression in the retinas of owls with different daily activity patterns
Journal of Photochemistry and Photobiology, 2022 Melanopsin is a photopigment found in a subset of retinal ganglion cells that is responsible for generating a series of responses to light in organisms, such as circadian rhythm regulation, pupillary light reflex, and body temperature control.

Optical imaging of human cone photoreceptors directly following the capture of light. [PDF]
PLoS ONE, 2013 Capture of light in the photoreceptor outer segment initiates a cascade of chemical events that inhibit neurotransmitter release, ultimately resulting in vision.
