Figure 9.

eCAP responses during continuous stimulation of 50 min in subject 1 (experiment B2). (A) eCAP was recorded in response to a pulse with the maximal current amplitude at 10 min intervals (average of 60 iterations). No significant difference in morphology was observed with increasing duration of stimulation (gray inset at 0.8 min from experiment A for comparison). (B) N-P magnitudes were smaller at all time points than for the same pulse without continuous stimulation in experiment A (gray horizontal line).
