ABSTRACT:
This invention provides a method for analyzing an electroencephalogram(EEG) using the correlation dimension by which the brain states can be discriminated. The method uses a time-delay determining method necessary for reconstructing vectors from the EEG time series, and a relative ratio of a correlation exponent.
