The retinal ON-OFF components giving rise to the delayed response

Summary

The delayed response from ON-OFF ganglion cells in the frog retina is preceded by a silent period during which strong inhibition occurs. The length of the silent period depends upon the stimulus flash intensity, the background illumination and the instantaneous adaptation level. Using various combinations of paired stimuli, it was concluded that the silent period and delayed response might be produced by the summation of a long lasting inhibitory component and a long lasting excitatory component. The present results suggest that the excitatory component is elicited by decreasing background illumination (light OFF), the inhibitory component by increasing background illumination (light ON).
