摘要：

Basic principles of magnetoencephalography (MEG) and neuromagnetic instrumentation are briefly reviewed. Our 24-channel system, based on planar gradiometer coils and dc-SQUIDs, is then described. Finally, recent MEG-experiments on human somatotopy and focal epilepsy, carried out in our laboratory, are presented.
