Photoreceptor proteins enable living organisms to sense light and transduce this signal into biochemical outputs to elicit appropriate cellular responses. Their light sensing is typically mediated by covalently or noncovalently bound molecules called chromophores, which absorb light of specific wavelengths and modulate protein structure and biological ...

Transducer noise in a photoreceptor
Nature, 1979IN our attempts to unravel the workings of visual systems, we seek neural responses and interactions which can account for visual behaviour. A popular measure of visual performance is the threshold intensity at which a stimulus is detected with a given probability.

Control of photoreceptor development
Current Opinion in Neurobiology, 1992Recent studies of cell type determination in the vertebrate retina suggest that rod photoreceptor development involves interactions among cells that are mediated, at least in part, by temporally regulated diffusible signals. In this review the strategies used to generate rods in the vertebrate retina are compared with those described for photoreceptor ...

Signal transduction in photoreceptors
Biochemical Society Transactions, 1991The biochemical role of the visual-pigment protein, rhodopsin, is reviewed, with reference to vertebrate rods and cones and the microvillar photoreceptors of invertebrates. New results are presented on the structure of squid rhodopsin, which possesses an extensive proline-rich repeat at its C-terminus, using negative-stain electron microscopy.

The Role of the Photoreceptor Membrane in Photoreceptor Optics
1975Many up-to-date studies have shown that various eyes and their photoreceptors which appear quite different at first sight exhibit striking similarity in their fine structure, physiology and chemistry. These similarities made us think that many optical properties of photoreceptors known at present could be traced back to the optical properties of the ...

Annelid Ciliary Photoreceptors
Science, 1965The photoreceptor cells of the tube-dwelling polychaete Branchiomma vesiculosum contain stacked disc-shaped membranous sacs which are the expanded and flattened outer membranes of cilia.

PHOTORECEPTOR ORGANELLES IN ANIMALS
Biological Reviews, 1964Summary1. The relatively high refractive index of rod and cone outer segments causes them to show wave‐guide properties.2. Rod outer segments have a positive intrinsic birefringence and a negative form birefringence. The former results from oriented lipid molecules, the latter from the disk structure of the outer segment.3. Electron microscopy of outer
