[Processing of a color signal by different types of ganglion cells in the frog retina].
On changing the stimulus color (max 436, 506, and 605 nm) just a few neurons only worked according to the opponent principle, a large group of slow-discharging on-off neurons altered the pattern of their discharge, and a considerable group of on-neurons was sensitive to the order of succession of colored stimuli. These latter cells generated response to a second stimulus with different time delays depending on the color of the first stimulus (the delay was registered starting from the end of response to the first stimulus). This is supposed to be one of the mechanisms of color identification, using not the spatial but the temporal comparison with another color.
