Histograms of linear scaling factors (K) between stimulation amplitudes that activate 50% of nerve fibers (i.e., I50 for A or B fibers) between all pairs of all individuals of different species with 0.25 ms pulse width for acutely implanted cuff; data for reverse translation of 0.25 ms and additional pulse widths (0.13 ms and 0.5 ms) are provided in Appendix 6 – Histograms of Linear Scaling Factors for Additional Pulse Widths
