Example of rectangular searchlights used to examine different subsections of our ROIs, superimposed on the flat map of the left hemisphere. Each color corresponds to a different searchlight (i.e., one point on the x-axis in B). Black outlines denote approximate boundaries of the different subdivisions of the ROIs (see also vertical dotted lines in B). White dotted lines indicate the three main sulci for our regions of interest: precentral sulcus (pre-CS), central sulcus (CS), and postcentral sulcus (post-CS). B. New crossnobis distance analysis (top) and corresponding ratio of the distances (bottom) during planning (no-go trials only, orange) and execution (blue). Black triangles denote approximate location of sulci as anatomical landmarks.
