Purkinje cells respond with complex firing to sensory stimulation (Fig. 4). For each type of stimulation, the number and percentage of statistically significantly responsive cells (peak response > average + 3 SD of baseline firing) is indicated (in parentheses: total number of cells tested). The response peak and response latency are indicated as medians ± interquartile ranges. Some stimuli recruited more Purkinje cells with statistically significant responses than others. The differences in fractions of responsive Purkinje cells were statistically significant (6 × 2 χ2 test) and further tested using pair‐wise Fisher's exact tests (as the χ2 test was significant, no further correction for multiple comparisons was applied). Bold numbers indicate statistically significant values. UL = upper lip; LL = lower lip; Ch = cheek; SO = sound only.
