Responses to symmetric biphasic pulses. a, b Comparison of thresholds and spike latencies for a monophasic cathodic pulse and a cathodic leading symmetric biphasic pulse. Predictions are indicated by the black squares, and distributions of the data from Miller et al. (2001a) are shown by the purple kernel density functions. c Predicted effect of PPD on the difference between monophasic and biphasic pulses of both polarities (lines) along with corresponding data from Miller et al. (2001) (M01-CA) and Shepherd and Javel (1999) (SJ99AC, SJ99CA). d Predicted effect of PPD on the threshold for symmetric biphasic pulses of anodic (AC) or cathodic (CA) leading polarities (lines) along with the corresponding data from Shepherd and Javel (1999) (SJ99-CA) and Smith and Finley (1997; SF97-AC). e Predicted effect of PPD on the RS (lines) along with the corresponding data from Bruce et al. (1999) (B99-4, B99-2, B99-10) and Miller et al. (2001) (M01).
