[Cyclic interaction of brain structures in different states and different types of activity].

Special method of multichannel EEG analysis with the aid of the matrix of consistent zero-crossing points distribution within the multichannel EEG registration calculated for the different functional states and behaviour revealed the cyclic forms of bilateral interrelationship between the brain structures. The variety of consistent connections increases in EEG-biofeedback food behaviour and visual stimulation, but the cycles prolongation decreases. The combination of zero-crossing points consistently distributed for different brain structures is typical for each functional state.
