Figure 2.

Distribution of the active contact locations after one year in a ventral, anterior, and lateral view. The gray shape represents the generalized STN, identical for all patients. Locations are color-coded corresponding to their contralateral off-medication stimulation effect. Overall, the distribution of the locations is centered on the anterior part of the dorsolateral STN. The relation with stimulation effect is most striking in the anterior view, where the locations at the lateral and ventral part of the distribution often correspond to good stimulation effect (red), while locations at the medial and dorsal part of the distribution often corresponding to poor stimulation effect (yellow). (A = anterior, D = dorsal, L = lateral, M = medial, P = posterior, and V = ventral, locations displayed on the axes are in mm).
