a, Linear fits are equivalent to power law fits for single-electrode and multielectrode ICMS, but power law fits are better for mechanical stimuli. b, Variability of magnitude ratings is lower for multielectrode stimulation than for single-electrode stimulation (Tukey’s post-hoc test, p < 0.01) and statistically equivalent to its mechanical counterpart (p = 0.45). c, JNDs are significantly lower for single than multielectrode biomimetic stimulation when expressed in terms of charge per phase (1-way ANOVA, F = 36.1, p < 0.001). Box and whisker in B and C represent 5th, 25th, 50th, 75th, and 95th percentiles.
