Research Abstract |
Basic characteristics of electric field distribution in cerebral cortex induced by a magnetic coil array were investigated. The array has the same arrangement as that used in a 306-channel whole-cortex MEG system. The coil currents were determined by the weighted least squares and characteristics of the induced electric fields were analyzed with the data resolution matrix of the inverse problem. The matrix provided a variety of quantities and procedures useful to estimate the basic response of the system.
