FootSim demonstrates realistic absolute firing threshold values

Top row: Empirically measured absolute firing thresholds for afferents from all four classes over a range of different frequencies, obtained using a circular probe with 3 mm diameter. Each line with different color shade represents a different recorded afferent. Bottom row: Modeled absolute firing thresholds of the afferents using identical stimulation parameters as in experimental setup. Absolute threshold is defined as the minimal applied stimulation indentation level with specific frequency that results with the afferent firing rate of 1 Hz. Each line represents a different model fit. Experimentally recorded afferent and its modeled replication in FootSim are presented with the same color on the top and bottom panel.
