Change in S1 and S2 FS neuron spiking evoked by ipsilateral whisker stimuli. A, FS neurons are identified by a spike waveform TtoP time <0.4 ms, and RS neurons by TtoP >0.5 ms. B, Example spike raster plots and PSTHs for one S1 (red) and one S2 (blue) FS neuron with increased spiking in response to ipsilateral whisker stimulation. C, Mean spike rate change evoked in 74 S1 FS neurons by ipsilateral stimuli with corresponding contralateral stimulus-evoked spike rate change. D, Same as in C, but for 98 S2 FS neurons. E, Ipsilateral stimuli elicit an increase in spike rate in S2 FS neurons (S1: 0.11 ± 1.29 spikes/s [n = 74], median ± MAD, p = 0.48, two-sided sign test, S2: 0.61 ± 1.72 spikes/s [n = 98], p = 0.032, S1 vs S2: p = 0.098, two-sided Wilcoxon rank-sum test). Contralateral stimuli elicit an increase in spike rate of similar amplitude in S1 and S2 FS neurons (S1: 14.84 ± 10.29 spikes/s [n = 74], median ± MAD, p = 7.16 × 10−18, two-sided sign test, S2: 12.49 ± 12.51 spikes/s [n = 98], p = 2.87 × 10−9, S1 vs S2: p = 0.12, two-sided Wilcoxon rank-sum test). The box plot whiskers extend from the smallest data point comprised within 1.5x the interquartile range of the 1st quartile to the largest data point comprised within 1.5x the interquartile range of the third quartile. NS, p ≥ 0.05.
