Figure 4

Horizontal eye position traces during lateral canal stimulation of monkeys A–D with a 2s-long pulse train. The black bars indicate the duration of the stimulation pulse train and the dashed lines mark the off period of the laser target. Electrically-evoked slow-phase nystagmus was observed in three animals (monkeys A–C) but not in monkey D. The current amplitude, pulse rate and pulse width were set individually for each animal at: (A) 100 µA, 300 pps, 400 µs; (B) 20 µA, 300 pps, 100 µs; (C) 100 µA, 300 pps, 100 µs; and (D) 100 µA, 600 pps, 400 µs.
