Figure 3.
Response waveforms from bipolar stimulation in quietly resting subjects. The stimulus began at time 0. The same responses are plotted on two time scales: in the left column, the time scale runs from 0 to 10 ms and in the right column the time scale runs from 0 to 70 ms. Shading indicates the observed range for P3 (left) or P15-25 (right). The subject's perception for stimulation of the bipolar pair for the entire dynamic range is labeled within the colored ovals; the subject's perception of sensation at the current level used for EABR recording is in parentheses under the ovals. A) Subject 1, electrode pair 11-20; B) Subject 2, electrode pair 13-22; C) Subject 1, electrode pair 12-21. D) Subject 2, electrode pair 21-20, E) Subject 2, electrode pair 4-13, and F) Subject 4, electrode pair 20-21.
