List of the brain regions showing a significant connectivity with the pre‐SMA (one sample t test, P < 0.05, FWE corrected). The coordinates are given as stereotaxic coordinates referring to the atlas of Talairach and Tournoux. Positive t value means positive connectivity between the brain regions and pre‐SMA; Negative t value means negative connectivity between the brain regions and pre‐SMA; L, left; R, right; M1, primary motor cortex; PMC, premotor cortex; pre‐SMA, rostral supplementary motor area; SD, standard deviation.
