Abstract :
A high-resolution magnetoencephalographic mapping method using a 64-channel SQUID (superconducting quantum interference device) system and MRI (magnetic resonance imaging) is described. The brain magnetic field is considered to be produced by current sources. The localization of current sources is performed via computation using Biot-Savart´s equation based on MEG. After matching the coordinate of the SQUID system to the coordinate of MRI, each current source location is mapped into the anatomical MRI data.<>
