Sagittal representation of the combined volume of stimulation from the active electrodes at the group level overlaid on the motor thalamic atlas region (Oxford thalamic connectivity atlas, Vim represented as green and ventral oralis anterior and posterior nuclei with bottle green). The group-level volumes of activated tissue (VTA) are represented in orange, while a higher overlap (80% or greater) between individual VTAs is shown in yellow color. The VIM target's average distance from the lateral wall of the third ventricle was 10.1 mm (SD 1.55). The target was on an average of 8.83 mm (SD 1.35) anterior to the posterior commissure.
