Fig. 4: Relationship between indentation stimulus intensity and response of the SNN second-order neurons.

a, Indentation force profile presenting stimulus plateaus (force level 1, ~0.4 N; force level 2, ~2.3 N). b, Spiking activity of the 1,036 CNs of the SNN second layer. c, Somatotopic maps of the CN activations (cumulative spike numbers over 1 s of stimulus) for the two force levels of the sample indentation in a. d, Distributions of the number of active CNs at the two force levels for 1,655 indentations. The median is indicated by a solid line within the box, whose edges represent the first and third quartiles; the whiskers extend to 1.5 times the IQR beyond the quartile boundaries.
