Color-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 blindness and its illuminations
In 1974, not long after an antenna was implanted in his skull, the British artist Neil Harbisson became the first person in history to be officially recognized as a cyborg.1 A cyborg—short for cybernetic organism—is a living thing formed from the integration of organic and mechanical parts. Before becoming a cyborg, Harbisson struggled as an art student afflicted with achromatopsia, an extremel...
متن کاملGene Therapy for Color Blindness
Achromatopsia is a rare congenital cause of vision loss due to isolated cone photoreceptor dysfunction. The most common underlying genetic mutations are autosomal recessive changes in CNGA3, CNGB3, GNAT2, PDE6H, PDE6C, or ATF6. Animal models of Cnga3, Cngb3, and Gnat2 have been rescued using AAV gene therapy; showing partial restoration of cone electrophysiology and integration of this new phot...
متن کاملOpsin genes, cone photopigments, color vision, and color blindness
In this chapter, we introduce the molecular structure of the genes encoding the human cone photopigments and their expression in photoreceptor cells. We also consider the consequences that alterations in those genes have on the spectral sensitivity of the photopigments, the cone photoreceptor mosaic, and the perceptual worlds of the color normal and color blind individuals who possess them. Thr...
متن کاملCortical color blindness is not "blindsight for color".
Cortical color blindness, or cerebral achromatopsia, has been likened by some authors to "blindsight" for color or an instance of "covert" processing of color. Recently, it has been shown that, although such patients are unable to identify or discriminate hue differences, they nevertheless show a striking ability to process wavelength differences, which can result in preserved sensitivity to ch...
