Electric responses of the human retina to moving stimuli.
Electric responses were recorded in the eyes of two normal subjects in response to a checkerboard pattern moving one square backwards and forwards (2 deg 44') at speeds varying between 13.5 and 2700 deg/s. The recorded waveforms suggest that a low-speed range (up to 250 deg/s) associated with increasing low-frequency response components can be distinguished from a high-speed range accompanied by increasing high-frequency wavelets. The range of velocities used is compared with target speeds employed in previous psychophysical and retinal single-unit recordings.
