The Neural Control of Vision
H. The Function of the Midget and Parasol Channels in Vision


flicker perceptionFlicker perception was studied using light emitting diodes (LEDs) laid out as shown in Figure 37. On each trial one of the LEDs was set to begin flickering after the monkey fixated the central LED. The rate of the flicker was varied. Parvo lesions produced no deficits on this task even when red/green flicker was used instead of ON/OFF flicker. The magno lesion produced a major deficit.
