Latest Color vision Stories
The vision system used to process color is separate from that used to detect motion, according to a new study by researchers at New York Universityâ€™s Center for Developmental Genetics and in the Department of Genetics and Neurobiology at Germanyâ€™s University of WÃ¼rzburg.
Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated.
WASHINGTON (Reuters) - Primates may have evolved color vision not to find the ripest, tastiest fruit but to detect that tell-tale blush on someone else's rump, U.S. researchers reported on Thursday.
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using photoreceptors that are attuned to particular wavelengths of light. By studying a special group of closely-related fish species inhabiting the Great Lakes of Africa, researchers have uncovered clues to...
