Abstract :
The goal of this digest is to develop a quantitative understanding about the shape and the volume of tissue activated (VTA) and stimulation site by deep brain stimulation (DBS) in deep brain area like subthalamic nucleus (STN) to improve neural stimulation. Current steering approach has been used in cochlear implant systems. In this digest, a novel current steering approach is applied to deep brain stimulation. Finite element models of deep brain stimulation based on current steering is used to compute the volume of tissue activated.
