Abstract :
A method of obtaining a continuous record of the average center frequency of the EEG and the instantaneous phase fluctuations about that average is described. A phase-locked loop with a wide range phase detector has been implemented on a hybrid computer for this purpose. This new technique provides another way to extract information from the EEG and tends to emphasize the time-varying features of such recordings.
