Circadian rhythmicity and light sensitivity of the zebrafish brain
, 2013 Light is important for entraining circadian rhythms, which regulate a wide range of biological processes. Zebrafish have directly light responsive tissues (Whitmore et al 2000) and are thus a useful vertebrate model for circadian rhythmicity and light ...
Moore, HA

, 2006 Vertebrate photoreceptor cells are polarized neurons highly specialized for light absorption and visual signal transduction. Photoreceptor cells consist of the light sensitive outer segment and the biosynthetic active inner segment linked by a slender ...

Neuronal induction of mouse embryonic stem cells following coculture with chick embryonic somites [PDF]
purpose: The aim of the present study was to understand if EBs can promote generation of neurons following co – culture with chick embryo somites. Materials and Methods: The mouse ES cells, line Royan B1, were cultured in hanging drops to induce ...

The role of Xenopus Rx-L in photoreceptor cell determination
, 2009 Members of the Rx (retinal homeobox) gene family play vital roles during eye development. In Xenopus, as in most other vertebrates, two Rx-type genes have been described.

P2X7 Receptor Modulation of Visual Responses in the Retina
, 2015 Adenosine 5’ triphosphate (ATP)-gated P2X7 receptors (P2X7Rs) are known to act as conduits for photoreceptor and retinal ganglion cell (RGC) damage, consequences of various neurodegenerative conditions within the visual pathway. Growing evidence supports

A neurobiological and computational analysis of target discrimination in visual clutter by the insect visual system. [PDF]
, 2009 Some insects have the capability to detect and track small moving objects, often against cluttered moving backgrounds. Determining how this task is performed is an intriguing challenge, both from a physiological and computational perspective.

, 2004 Melanosomes within the retinal pigment epithelium (RPE) of mammals have long been thought to exhibit no movement in response to light, unlike fish and amphibian RPE.

Bat eyes have ultraviolet-sensitive cone photoreceptors
, 2009 Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

Encoding of light by the cone photoreceptor synapse [PDF]
, 2009 Retinal photoreceptors are the primary sensory neurons responsible for vertebrate vision. The photoreceptor converts light into a voltage signal that modulates neurotransmitter release at the photoreceptor synapse.
Jackman, Skyler Lofstrand

, 1987 We have identified a second Drosophila opsin gene, Rh4, which is expressed specifically in the ultraviolet-sensitive R7 photoreceptor cells. The two R7 opsins, Rh3 and Rh4, are expressed in nonoverlapping subsets of R7 cells.
