In this paper, we have proposed multiscale fractal dimension (MSFD) technique to characterize signals at multiple time scales. In this technique, multiple scales of the signal are obtained by segment averaging and the complexity of the resulting signals at those scales is quantified using multiresolution area-based fractal dimension measure. The technique is applied to intracranial EEG records and...
In this paper, we have studied electroencephalogram (EEG) activity of schizophrenia patients, in resting eyes closed condition, with detrended fluctuation analysis (DFA). The DFA gives information about scaling and long-range correlations in time series. We computed DFA exponents from 30 scalp locations of 18 male neuroleptic-naïve, recent-onset schizophrenia (NRS) subjects and 15 healthy male control...
