title: Comparison of magnetoencephalography with other functional imaging techniques.
abstract: Recent advances in instrumentation and analysis in biomagnetism offer a unique tool for studying the spatiotemporal evolution of spontaneous brain activity as well as activity evoked by a stimulus. The overall performance characteristics of this and other techniques used to study the dynamics of brain function are compared. Particular emphasis is placed on defining the general spatiotemporal window of brain activity that each technique makes accessible. Similarities and differences associated with diverse modelling schemes for extracting source current density properties from electrographic recordings are stated.
