Functional localization based on measurements with a whole-head magnetometer system

Whole-cortex magnetometers represent a significant methodological breakthrough in noninvasive studies of the brain's electrical activity. This paper describes our 122-channel instrument with planar gradiometers, methods to interpret its data, and gives a few examples of neuromagnetic studies.
