Modelling and Simulation Radial and Tangential Dipoles of Human Head Local Field Potentials

Abstract:

The mathematical tangential and radial dipole models were constructed. Dipoles can be use to answer if any special electrical and magnetic patterns exist in human head, and also use them to reveal many other magic phenomena of head nero-system. Construct of a mathematical models of the electric potentials. Use validation of the mathematical model and interrogation of the validated model to determine what sort of dipole separation would produce patterns. Our models were simulated by using MATLAB. Simulation clearly show that those tangential and radial dipole models reflected real dipoles physical and electrical characteristic of them. Those models show that even with spatial filtering, the electrode array can not be more than 4.5 mm above the surface of the cortex for the sorts of patterns we are looking for to be resolved.
