深部脑刺激有限元模型仿真研究

linical and experimental studies reveal that, deep brain stimulation can inhibit the intractable brain diseases and mental disorders, such as Parkinson epilepsy and depression. It provides a new way to study the mechanism of deep brain stimulation that using the finite element simulate deep brain stimulation and electrode current distribution in the brain tissue. In this paper, the finite element is used to simulate deep brain stimulation model. Considering the electrode-brain interface, we simulateand analyse the current density and electric field distribution of organization under the stimulation mode of single electrode，dual-electrode and multi-electrode. The study lays the foundation for further analyse the impact of deep brain stimulation on neurons and neural network.
