FIGURE 1.
(A) Discharge (left ordinate) of an irregular unit (standardized coefficient of variation, CV* = 0.42) in response to anodal (solid curve) and cathodal (dashed curve) 100-µA currents delivered to the contralateral ear. Bar histogram: Averaged response to the two current polarities (right ordinate). (B) Averaged responses of a regular unit (CV* = 0.04) to 100- and 200-µA contralateral currents. (C) Relation between response magnitude and discharge regularity. Each point represents a separate unit. The response was calculated as the average response during the first 2.5 s of 100-µA anodal and cathodal stimulation. Thick horizontal lines in A and B indicate 5-s current presentation.
