Characteristics of the responses evoked on the same SNr cell by electrical stimulation of the motor cortex in the different conditions.

The latency (L) and duration (D) of the different components of the cortically-evoked response were measured on the basis of post-stimulus time histograms generated from 50 cortical stimulations. Nb Sp: number of spikes.A: *1p = 0.016, Paired t-test; B: N.S., Paired t-test; C: *2: p 3: p = 0.027, One way Repeated Measures Analysis of Variance; *4: p = 0.021, One way Repeated Measures Analysis of Variance (Holm-Sidak Method for all RM ANOVA); D: *5p = 0.012, Paired t-test.
