Gert Pfurtscheller is Professor of Medical Informatics at Graz University of Technology, Director of the Institute of Biomedical Engineering at the University of Technology, and Director of the Ludwig Boltzmann Institute of Medical Informatics and Neuroinformatics. At present, he is involved in a number of research programs including the design of a "brain-computer interface," studies in functional brain topography using event-related desynchronization.
Christa Neuper is a Psychologist and a Research Assistant at the Ludwig Boltzmann Institute of Medical Informatics and at the Department of Medical Informatics, Institute of Biomedical Engineering, at Graz University of Technology. She teaches graduate courses at the Department of Psychology, University of Graz, since 1986, and at the Institute for Biomedical Engineering, Graz University of Technology, since 1996. Her research interests include the study of event-related oscillations in the brain, methodical aspects of EEG recording and processing, and neurophysiological applications.
Piotr J. Durka introduced adaptive approximations into the field of EEG analysis. As Assistant Professsor at the Warsaw University, he supervised M.Sc. thesis of Dobieslaw Ircha - implementation of stochastic dictionaries for MP. Current information on both of them is available from the Web page of the Laboratory of Medical Physics http://brain.fuw.edu.pl.
Cooperation which led to this paper from the very beginning was effectuated via Internet - the authors (from Poland and Austria) actually did not met in person. Email was the carrier for discussions, datasets, results, figures and finally the joint preparation of the manuscript.
