Amplitude and Correlational Mapping of EEG — A Software System
Since the times of Berger’s discovery (Berger, 1969), electroencephalography has undergone three major changes. There was a transition from single-channel to multi-channel recording; from analog to digital acquisition, storage and data-processing techniques; and from studies of punctually-derived potential differences to those of global potential field distributions, that is, from classical electroencephalography to topoelectroencephalography (see Petsche, 1976, for a historical review). Nowadays, topo-electroencephalography (TEEG) is becoming important, both in clinical practice as well as in the field of research. As a result, professional systems providing TEEG or, more popularly, “Brain Mapping” facilities have become commercially available, such as Brain Atlas (Biologic Systems), Pathfinder (Nicolet), or Brain Imager (Neuroscience). It would be precocious, however, to consider “home-made” systems obsolete; on the contrary, there is still an urgent need for methodical innovations, especially in experimental research work.
