Nodes of the BTC circuits in the left hemisphere are shown in italic fonts. P_FWEcorr: p value corrected for multiple comparisons (FWE) in terms of a height threshold. svc^‡: significant for small volume correction within connectivity-based striatal masks; svc^†: significant for small volume correction within anatomically defined premotor areas based on a probability map.
