(PhysOrg.com) -- Scientists have a good overall understanding of human vision: when light enters our eyes, it is focused by the lens and strikes the retina in the back of the eye. The light causes some of the millions of ...
Columbia scientists have identified a brain circuit that drives fruit flies' ability to see in color—and found that it bears a striking resemblance to the circuitry behind our own capacity for color vision. These findings ...
