Computational model used to determine the effects of the electrode geometry and peri-electrode tissue properties on recorded neural signals. (a) The finite element method (FEM) geometry of a Medtronic 3387 deep brain stimulation (DBS) electrode is shown, surrounded by a peri-electrode space domain, and implanted in a prism representation of the ventral intermediate (Vim) nucleus of the thalamus. The locations of 500 thalamocortical (TC) somata within Vim thalamus are indicated by the dots, and the axon positioning is shown for one neuronal unit, which includes a TC neuron and presynaptic inputs from the cortex (CTx), cerebellum (CER), reticular nucleus (RN), and thalamic interneurons (TIN). (b) Schematic description of electrode dimensions. (c) Synaptic connections between neural elements. Used with permission from [8].
