Supplementary Figure 2: Striatal response characteristics to cerebellar stimulation.

(a) The average stimulus threshold for producing a response in striatal response with electrical stimulation of the dentate nucleus. (b) The average striatal neuron response magnitudes (for both the excitatory and inhibitory periods) when the dentate nucleus was stimulated at the minimum threshold intensity that produced a detectable response. (c) The fractional change in the response of striatal neurons to electrical stimulation of the dentate nucleus as the stimulus intensity was increased. (d) The average laser power threshold emerging from the fiber optic for producing a detectable response in striatal neurons with optogenetic stimulation of the dentate nucleus. (e) The average striatal neuron response magnitudes (for both the excitatory and inhibitory periods) when the dentate nucleus was optogenetically stimulated at the minimum threshold intensity that produced a detectable response. All data shown are represented as mean ± S.E.M
