Molecular genetics of color vision and color vision defects.
Color is an extremely important component of the information that we gather with our eyes. Most of us use color so automatically that we fail to appreciate how important it is in our daily activities. It serves as a nonlinguistic code that gives us instant information about the world around us. From observing color, for example, we can find the bee sting on an infant's arm even before it begins...
متن کاملColor Vision Defects
The biological basis of color vision can be divided into two stages: the first is the light-sensitive cone photoreceptor cells in the retina and the second is the neural components that process information about wavelength gathered by the photoreceptors. Humans with normal color vision have three populations of cone photoreceptors that are classed according to their relative spectral sensitivit...
متن کاملColor-Vision and Color-Blindness
Special public attention was called to the subject in 1875 by an enquiry into the causes of a railway accident which had taken place in Sweden, from which it appears that colourblindness was the cause of the disaster. Our author having described colour-sensations, goes on to discuss the theories of colour-perception and colour-blindness, classifying the latter defect as total and partial. Total...

متن کاملColor vision.
Color vision starts with the absorption of light in the retinal cone photoreceptors, which transduce electromagnetic energy into electrical voltages. These voltages are transformed into action potentials by a complicated network of cells in the retina. The information is sent to the visual cortex via the lateral geniculate nucleus (LGN) in three separate color-opponent channels that have been c...
