Subject electrode placement (A,B) and diffusor tensor imaging (DTI) data (C,D). (A) Post-operative computed tomography (CT)-scans showing subjects’ electrode placements. Electrodes registered and displayed in the common Montreal Neurological Institute (MNI) space. (B) Electrode contacts in AC-PC coordinates and MNI space. Electrode order from most dorsal, C3, to most ventral, C0. (C) DTI-computed total connectivity derived from the number of voxels with non-zero connectivity with several regions of interest (ROI) available from two of three subjects. DTI connectivity is from the middle electrode contact pair C2-C1. Both left and right electrodes displayed connectivity to right superior frontal gyrus (SFG) and left supplementary motor areas (SMA). (D) DTI connectivity strength as mean intensity per non-zero voxels. Supporting total connectivity results, highest connectivity strength was with right SFG and left SMA.
