Abstract

Topographic mapping is increasingly popular method of representing brain electrical activity. We present a visualization method taking advantage of animated 3D topographic maps of brain electrical activity. Maps are projected onto real 3D model of human head and controlled with standard multimedia controls. Benefits of this approach are improved man-machine interface, enhanced readability, and possibility to trace hidden patterns of spatio-temporal brain activity
