Microstimulation can elicit pursuit and saccadic target velocity compensation to stationary targets. The eye position and speed traces show the component along the preferred–null axis, with upward deflections corresponding to the preferred direction. The receptive field was located 8.6° to the right and 2.8° up, the preferred direction was 225° (inset), and the receptive field diameter was 8° (shaded bars). The current level was 80 μA. The speed tuning at this site was not tested. No Stim, Nonstimulated trials;Stim, stimulated trials.
