Example of AGF recordings. Fixed latencies were used for N1 (233 µs) and P2 (575 µs). The left columns show the single ECAP waveforms as a waterfall plot. ECAP waveforms with matching stimulation intensity are marked with identical colors. For better readability, the large amount of available ECAP waveforms in the FineGrain AGF paradigm is plotted in gray. Note that always the full dataset is processed to generate the quasi-continuous amplitude growth function shown on the right columns. Row a shows the paradigm Standard AGF (25 averages per stimulation level). Row b paradigm FineGrain AGF (without moving average) and ce with a moving average over 7, 13 and 25 different stimulation levels, respectively. For row a, e, the mean visual ECAP threshold is plotted as a dash-dotted line
