Responses to stimulation amplitudes determined by multiplying the mean I₅₀ for A or B fibers in a given species by the mean linear scaling factor (K) of a given species pair, using a 0.25 ms/phase biphasic waveform for acutely implanted cuff. The left and right columns provide the Ks from smaller to larger species and from larger to smaller species, respectively. Each data point denotes the response of A (orange) or B (blue) fibers across each individual. The horizontal line denotes the median, the box denotes the upper (Q3) and lower (Q1) quartiles, and the upper and lower whiskers show Q3 + 1.5*(Q3-Q1) and Q1—1.5*(Q3-Q1), respectively
