Simulation study of electromagnetism forward problem of brain impedance network

Based on electromagnetism and electricity network theory a kind of brain impedance network mode is built in the paper. And in order to study the relation between impedance of bleeding or shortness of blood encephalic and skull potential, we establish emulation model and carry through a series of simulation calculation. In these result, it is indicated that skull has some inhibition for current, but has not entirely constrain current and also has conductance characteristic. In addition, the factors of the position of impedance being changed, impedance amplitude being enlarged or reduced, impedance being changed and area being enlarged and so on, all these can bring great influence to boundary potential.
