Summary

The goal is to establish another anatomical referencing system in order to achieve an even higher accuracy when implanting stimulation electrodes.

Detailed description

The main goal is to find out what are the optimal distances to these reference fiber tracts when stimulating and to find the optimal target. This has to be evaluated for each target, such as globus pallidus (Gpi), subthalamic nucleus (STN) and ventral intermediate nucleus of the thalamus (VIM) separately. This is of special importance as the investigators can demonstrate the internal capsule, which is often a generator of stimulation-induced side effects: tetanic muscle contractions, dysarthria and gaze deviations.
