Convergence of different sensory streams on individual Purkinje cells

Stimulation	Difference from chance (Z)
	Upper lip	Lower lip	Cheek	Sound only	LED
Whisker pad	1.21	1.25	0.85	1.34	2.75**
Upper lip		1.23	2.00*	1.34	1.94
Lower lip			2.39*	2.70**	2.62**
Cheek				3.31**	3.10**
Sound only					2.28*

For each type of stimulus, we compared the observed rate of convergence on individual Purkinje cells to chance level, using a bootstrap method based on the relative prevalence of responses to each stimulus (cf. Fig. 5). The difference from chance is indicated by Z values. All combinations occurred more often than expected (Z > 0). The P values of these correlations underwent Benjamini–Hochberg correction for multiple comparisons. ^* P < 0.05; ^** P < 0.01.
