Stimulus induced first spike latencies of neurons in S1 and V1. Values are displayed as mean ± SEM for both unimodal (uni) and bimodal (bi) stimulations. Significant differences between stimulations are indicated in parentheses (n.s., not significant; *p < 0.05, **p < 0.01, ***p < 0.001, Wilcoxon signed-rank test).
