<table>Third ventricle in lateral view with the stereotactic baselines for calculation: anterior-posterior commissure (CA-CP) line and the Foramen Monroi-posterior commisure (FM-CP) which was used in case the commissura anterior was not clearly visible. The red points mark the target points in relation to the baselines CA-CP and FM-CP. a: v.o.a. nucleus of thalamus for treating the rigor, b: v.o.p. nucleus of thalamus for treating tremor, c: Forel H field.</table>
