Abstract

We present an analysis of the spatio-temporal patterns connected with the electrical activity of the brain which is measurable at the human scalp in the form of electroencephalograms (EEGs). In the case of the so-called Alpha activity the spatio-temporal EEG patterns show large scale spatial coherence which, however, undergoes a complex temporal evolution. We discuss the change of the spatio-temporal patterns during an epileptic seizure. Based on the synergetic theory of pattern formation in nonequilibrium systems we present a model of the Alpha EEG rhythm which reproduces the observed main spatial as well as temporal features.
