Abstract
An apparatus and method for display of biologically induced electrical activity is disclosed. The apparatus includes sensors for measuring EEG or MEG signals from a living body and using these signals to compute one or more dipoles representative of the measured electrical activity. Values of the electrical activity may also be computed for discrete locations in or on the body. The operator has the ability to input a variety of different computational specifications or criteria to facilitate dipole computation. The resulting computed data may be selectively displayed as a dipole within a three-dimensional representation of the body, as a movie-like series of dipoles, as a composite or tracing of dipoles or as various topographic maps. The operator also has the ability to change the display to provide different perspective views or to enlarge the displayed scene.
