Fig. 5.
Representative single-unit responses to the four combinations of dot and window velocity in the patch experiment. Thetop row provides schematic drawings of the stimulus; thefilled dots and arrows indicate the speed of dot motion and the open arrows indicate the speed of window motion. The middle row and bottom row show the responses of two MT neurons to the four stimuli. The neuron in the middle row had a preferred speed of 33°/sec. The neuron in the bottom row had a preferred speed of 10°/sec. Each histogram shows the firing rate of the neuron in response to the stimulus shown above the histogram. Bin width was 16 msec. The bars underneath each histogram indicate the interval of stimulus motion.
