Indeed, bioinformatic analysis led him to predict the existence of a mysterious protein: COCO, a "recombinational" human molecule that is normally expressed within photoreceptors
during their development.
However, when complement factor B was inhibited the photoreceptors
were protected, staving off cell death for longer.
As the mantis shrimp scans an object, the image moves between different photoreceptors
, each of which responds differently, and it is this sequence, rather than comparisons between the photoreceptors
, that they use to identify colours.
Our research has demonstrated the feasibility of restoring visual responses after the loss of light-sensitive photoreceptor
cells in animal models," said Pan.
These results demonstrate that gestational lead exposure resulting in blood lead levels of 10 [micro]g/dL alters retinal development by selectively promoting the development of rod photoreceptor
cells and bipolar cells.
These colorful crustaceans take the prize for most unusual eyesight, with at least 16 different types of photoreceptors
, including ones sensitive to ultraviolet light.
The ciliary opsins of vertebrates can be introduced by the well studied function of rhodopsin found in the photoreceptors
The animals suffered blindness due to the loss of photoreceptor
(light-sensing) cells that line the back of the eye, or retina.
The retina is a thin, delicate piece of tissue in the back of the eye that is comprised of a variety of different neuronal cells, including 125 million photoreceptors
(rods and cones) that process light and enable you to see.
Dr Jane Sowden said: "Remarkably, we found the mature retina is in fact able to support development of new functional photoreceptors
Two main approaches exist: the epiretinal approach in which the implant is placed on the vitreal side of the retina  and the subretinal approach in which the implant replaces degenerated photoreceptors
Induction motors, photoreceptors
, thyristors, diodes, even computers, the whole world of electronics (as opposed to the technology of electro-magnetism) have been missed out.
