Abstract

Variations in the size of a stationary spot stimulus differentially affected the "on" and "off" discharges of the majority of the visual cells in the hamster's superior colliculus which responded reliably to stimuli flashed within the activating region of the receptive field. Such differential effects were evident in the pattern of discharge magnitudes and/or latencies which were exhibited by those neurons in response to different size spots. The results were interpreted as suggesting that the "on" and "off" discharges of the majority of the collicular neurons in the hamster may code the spatial aspects of visual stimuli in a relatively independent manner. © 1977.
