Abstract

The chaotic properties of the EEG signals are evidenced by means of fractal spectra. The method involved in computing is based on the so-called Rényi entropy. The fractal spectra are clearly changed according to the state of the subject and this proved to be a good indicator in preictal and ictal states of epileptic patients. Another possible application of the fractal spectrum is the one in which, in a Donchin paradigm, active electrodes may be evidenced based on P300 evoked potentials.
