Figure 6. Stimulus waveform and electrode size influence the range of thresholds.

Figure 6

(a, left) Thresholds in the high- and low-threshold models (see text) are plotted as a function of the position of the stimulating electrode (vertical tick marks and circles, respectively) for biphasic waveforms. (a, right) Overlay of the biphasic response and the cathodal response. LE: distance from the soma to the left (proximal) edge of the band (in µm); RE: distance from the soma to the right edge of the band. (b) Thresholds are plotted in response to stimulation from disk electrodes in the high- and low-threshold models. The diameter of the disk electrode was 10, 50 and 200 um (left, middle and right panels). RE1 indicates the right edge of the band for the high-threshold model; RE2 is the right edge for the low threshold model.
