Figure 4: Context and condition dependent changes in SNr activity.

A) Significant differences in selectivity between U (unpatterned) and P (patterned) contexts were found during sensory processing, movement preparation, and movement initiation epochs. priors, p = 0.100, Wilcoxon signed rank test; sensory processing, p = 0.0311*, Wilcoxon signed rank test; p = 0.0231*, Cohen’s d = 0.364, permutation test; movement preparation, p = 0.0284*, Wilcoxon signed rank test; p = 0.0234*, Cohen’s d = 0.220, permutation test movement initiation, p = 0.0284*, Wilcoxon signed rank test; p = 0.00376*, Cohen’s d = −0.284, permutation test; feedback, p = 0.482, Wilcoxon signed rank test. Within session data comparisons are represented by connecting line, overall mean indicated by black outlined data points; n.s. (not significant), sens. proc. (sensory processing), move. prep. (movement preparation), move. init. (movement initiation). B) As in A) for ipsi. (ipsilateral) compared to contra. (contralateral) responses, no significant differences found: priors, p = 0.322, Wilcoxon signed rank test; sensory processing, p = 0.322, Wilcoxon signed rank test; movement preparation, p = 0.344, Wilcoxon signed rank test; movement initiation, p = 0.322, Wilcoxon signed rank test; feedback, p = 0.322, Wilcoxon signed rank test. C) As in A) for U ipsi. compared to P ipsi. responses, significant differences found across all epochs;: priors, p = 0.00740*, Wilcoxon signed rank test; p = 0.0183*, Cohen’s d = 0.333, permutation test; sensory processing, p = 0.0164*, Wilcoxon signed rank test; p = 0.0178*, Cohen’s d = 0.484, permutation test; movement preparation, p = 0.00610*, Wilcoxon signed rank test; p = 0.00475*, Cohen’s d = 0.327, permutation test; movement initiation, p = 0. 00610*, Wilcoxon signed rank test; p = 0.000615*, Cohen’s d = −0.422, permutation test; feedback, p = 0.0164*, Wilcoxon signed rank test; p = 0.0250*, Cohen’s d = −0.253, permutation test. D) As in A) for U contra. compared to P contra. responses, no significant differences found across any epochs: priors, p = 0.0805, Wilcoxon signed rank test; sensory processing, p = 0.0885, Wilcoxon signed rank test; movement preparation, p = 0.0885, Wilcoxon signed rank test; movement initiation, p = 0. 0885, Wilcoxon signed rank test; feedback, p = 0.0805, t-test. (Not pictured) As in A), for correct compared to incorrect responses, no significant differences found across any epochs: priors, p = 0.360, Wilcoxon signed rank test; sensory processing, p = 0.461, Wilcoxon signed rank test; movement preparation, p = 0.382, Wilcoxon signed rank test; movement initiation, p = 0. 382, Wilcoxon signed rank test; feedback, p = 0.0855, t-test. (Note on statistics) All reported t-test/Wilcoxon-tests p-values have been adjusted for multiple (n=5) comparisons, represent paired comparisons, and are 1-tailed. Permutation test results listed only for comparisons with significant t-test/Wilcoxon-tests and always performed with 100,000 iterations (Supplementary Materials and Methods).
