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 ...

Light Activation of the Phosphoinositide Cycle in Intrinsically Photosensitive Chicken Retinal Ganglion Cells [PDF]
, 2010 Purpose: In vertebrates, intrinsically photosensitive retinal ganglion cells (ipRGCs) acting as nonvisual photoreceptors transmit environmental illumination information to the brain, regulating diverse non–image-forming tasks.

Functional Imaging of the Outer Retinal Complex using High Fidelity Imaging Retinal Densitometry [PDF]
, 2020 We describe a new technique, high fidelity Imaging Retinal Densitometry (IRD), which probes the functional integrity of the outer retinal complex. We demonstrate the ability of the technique to map visual pigment optical density and synthesis rates in ...

Melanopsin-expressing retinal ganglion cells are resistant to cell injury, but not always [PDF]
, 2017 Melanopsin retinal ganglion cells (mRGCs) are intrinsically photosensitive RGCs deputed to non-image forming functions of the eye such as synchronization of circadian rhythms to light-dark cycle.

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.

Fast recursive filters for simulating nonlinear dynamic systems [PDF]
, 2007 A fast and accurate computational scheme for simulating nonlinear dynamic systems is presented. The scheme assumes that the system can be represented by a combination of components of only two different types: first-order low-pass filters and static ...

Light-dependent changes in outer segment free-Ca2+ concentration in salamander cone photoreceptors. [PDF]
, 1999 Simultaneous measurements of photocurrent and outer segment Ca2+ were made from isolated salamander cone photoreceptors. While recording the photocurrent from the inner segment, which was drawn into a suction pipette, a laser spot confocal technique was ...

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.
