Bilateral STN-DBS active contact positions of 20 patients with Parkinson's disease plotted in the coronal plane with respect to weight gain.

<p>Patients (N = 11) with at least one active contact (a) placed within 9.3-mm of the wall of the third ventricle gained significantly more weight than patients (N = 9) with both contacts (b) located more laterally (p<0.001).</p>
