DBS model. The subthalamic nucleus (green volume) represents a common anatomical target for the DBS lead (grey shaft, pink electrode contacts) shown passing through the thalamus (yellow volume). The stimulation protocol specified the waveform and the amount of current injected through each contact. The voltage distribution in the tissue medium generated during current-controlled stimulation was determined from a finite element model with the total current amplitude divided between adjacent electrode contacts.
