Dictionary » P » Photoreceptor PhotoreceptorPhotoreceptor (Science: cell biology) A specialised cell type in a multicellular organism that is sensitive to light. This definition excludes single celled organisms, but includes noneye receptors, such as snake infra red (heat) detectors or photosensitive pineal gland cells. See: retinal rods, retinal cones. Structures or pigments that react when light is present (as a [[stimulus). ![]()

Results from our forumThe Mind Portal and Biology... say 3 colored dots, and how the reflected light waves from these dots travel through space to the eyes, passing through the lens and reaching the photoreceptor cells, where they are transmitted into an image as sensed within the brain. This is not a simple process that we can dismiss with a few ...

A response on unilateral deuteranopia...... Objects appear colored because they reflect light from particular regions of the visual spectrum and the light that is reflected is picked up by photoreceptors in your retina. Cone shaped receptors are only found in the fovea (cones deal with color vision, detail vision and vision in high levels ...

Another new blue light receptor...?... In addition, we observed two minor peaks in the green (575 nm) and the red (675 nm) regions. The action spectrum suggests that a blue/UV-A light photoreceptor with a flavin-based chromophore participates in the HL response of Lhl4 gene expression. However, the hypersensitivity to near UV-B light ...

The Fiber Disease... that a photography is created. For this purpose, they fused a protein in the membrane of bacteria which normally do not have light receptors to a photoreceptor from another, light-sensitive, bacterial strain. The membrane protein of the bacteria which they had chosen directly regulates the expression ...
