Research on the Surface Potential of Spinal Cord based on the Finite Element Analysis

Finite element analysis can research the change of the structure and the interior field intensity of human and animal body organs and tissues through simulation experiment. We use finite element analysis software to analyze the spinal cord surface potential and research the transmission feature of signals generated by interneurons in spinal cord which are related with body motion control and sensory processing. A three dimensional model of electrical source in rat's spinal cord was built, the influence on potential distribution on spinal cord surface caused by position changes of electrical source in transverse direction and dorsoventral direction was analyzed and calculated. We obtained the potential distribution curves of spinal cord surface and compared the results with data from animal experiments, verifying the feasibility of scheme of locating the excitatory through potential distribution on spinal cord surface.
