Effect of interleaved stimulation on the slow-phase velocity of nystagmus elicited by stimulation of the most distal electrode in the lateral canal of subject VI07. a Horizontal slow-phase velocities of nystagmus elicited by stimulation of the most distal site on the electrode array at different current levels. Up is rightward velocity, and down is leftward velocity. b Vertical slow-phase velocities of nystagmus elicited by stimulation of the most distal site on each electrode array at different current levels. Up is upward velocity, and down is downward velocity. The stimulation parameters were 2-s train at 300 pps with 100 μs/phase and an 8-μs gap. Multiple trials of stimulation are represented. Symbols are means, and error bars are 1 SD. Colored symbols indicate the canal and cochlear stimulation site combinations stimulated. * p < 0.05: statistically significant result.
