Magnetic fields generated by bioelectric currents responsible for epileptic activity in the human brain have been measured by means of a movable magnetometer based on SQUID technology. Simultaneously detected magnetic and electric signals were studied by computing the covariance and dividing this quantity by the electric variance. The relative covariance so obtained was proved, to reliably reflect the distribution of magnetic field and, by means of an appropriate model, permitted 3D localization of the investigated epileptic source. |
