The goal of this project was to develop a quantitative understanding about shape of axonal tissue activated (STA) and stimulation site by deep brain stimulation (DBS) in middle brain like thalamus, subthalamic nucleus (STN), and globus pollidus interna (GPi) to make better stimulation effects. The volume of tissue activated (VTA) can be studied using different electrode dimensions.

The goal of this paper is to develop a quantitative understanding about the shape and the volume of tissue activated (VTA) and stimulation sites by deep brain stimulation (DBS) in deep brain area like subthalamic nucleus (STN) to improve neural stimulation. Monopolar current steering approach has been studied in cochlear implants and deep brain stimulation. In this paper, novel bipolar and tripolar current steering schemes are applied to deep brain stimulation. Finite-element models of deep brain stimulation are used to study the volume of tissue activated for monopolar, bipolar, and tripolar current steering configurations.
