其他摘要 |
PURPOSE: Human subjects are more sensitive to luminance decrements than luminance increments, as is evident by a lower threshold and shorter latency for dark stimuli. This asymmetry can be explained by the results of neurophysiological recordings in dLGN and V1 of cat and monkey. Specifically, V1 population responses demonstrate that black stimuli elicit a higher level of activation than white stimuli, while the response latency of OFF cells in dLGN is shorter than that of ON cells. The removal of a black or white spot often generates the perception of a negative afterimage. Here we ask whether increment and decrement stimuli also elicit asymmetrical negative afterimages? If so, can these asymmetries be attributed to the asymmetries for ON- and OFF-channels? |
