Effects of stimulation current on contralateral saccades. The amplitude (A), peak velocity (B), latency (C), and duration (D) of evoked saccades are documented for 3 sites: e18 (100 ms, 600 pps), b31 (100 ms, 400 pps), and b54 (100 ms, 600 pps). Means and SE are represented for each tested stimulation current. Filled symbols and solid lines, horizontal component; open symbols and dashed lines, vertical component.
