Testing Hypotheses About Visual Pigments Underlying Deutan Color Vision
A classical theory held that deuteranomaly was caused by the replacement of the normal M cone pigment by an anomalous M pigment, which was spectrally red-shifted. Two assumptions associated with that theory were: (1) that there was a single, fixed L pigment, shared by deuteranomals and normals; (2) and that everyone had two genes for cone pigments on the X-chromosome. Those two assumptions are ...
متن کاملMolecular 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: How the Cortex Represents Color
Our understanding of how we see color has benefited from the long tradition of visual psychophysics. More recently, models and methods from psychophysics are guiding modern neuroimaging experiments on color vision. Combining the two techniques can lead to discoveries that neither can make alone.
متن کاملThe Color Vision of Dichromats
1. Protanopes and deuteranopes show one maximum of wavelength discrimination which occurs near their neutral point in the region of 500 mmicro (blue-green for color-normal). The value of the just discriminable wavelength interval Deltalambda is about 1 mmicro at this point and is much like the normal. To either side of this, Deltalambda rises. It increases rapidly on the short-wave side, and sl...
