Brain Topography Aims and scope Submit manuscript


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.
