FootSim can produce realistic receptive field sizes and afferent responses to ramp-and-hold stimuli, replicating the natural behavior of specific afferent types

(A) Receptive field sizes measured experimentally (stars) and simulated with FootSim (circles) for different afferent classes. Kruskal-Wallis test didn’t show statistical difference (p > 0.05) of modeled and experimentally measured receptive field sizes, except for SA2 (0.01 < p < 0.05).

(B) Responses of different classes to the ramp-and-hold stimuli. Average population responses of the four different afferent classes (colored lines) to a ramp-and-hold stimulus (indentation trace shown as black line). The model reproduces canonical response properties of the four afferent classes, as have been widely reported in the literature.²⁴
