Abstract :
The authors analyzed the EEGs of 12 schizophrenic patients and 12 control subjects by means of methods from nonlinear dynamical system theory. From the EEG data, they reconstructed the chaotic dynamic attractors expressed in the phase space and calculated their correlation dimensions (D2), which are a measure of the complexity. The authors´ results showed a diminished complexity in the EEGs of the patients
