Abstract

The responses to red stimuli presenting different distributions of time luminance are compared. The height of the x wave seems to be independent of time distribution of the light stimulus while the height of the b wave is greater, the greater the time of variation of the luminance. The latencies to peak of both waves are greater with a slowly rising stimulus than with a steep stimulus.
