Average (mean ± s.d.) activity (integral of firing rate, ‘Int. FR’) across stimulus-responsive units 15–50 ms after stimulation onset (of hand or hand + S1) along with the statistical intra-recording comparison (Wilcoxon’s signed rank test, 4 recordings from 4 mice). All p-values remained significant after false discovery rate correction for multiple comparisons.
