An approach for representing EEG activity.
A method for the representation of EEG-parameters by means of a bidimensional plot of two signals is described. A block diagram is given for the recording of figures with phase-sensitive parameter variations, using an oscilloscope or an X-Y graphic recorder as a display. Charts for the determination of the setting parameters of a digital as well as an analog phase-shifting arrangement are submitted. The method is capable of reflecting individual properties of a single wave and typical characteristics of the epoch as well. It is felt that it may be of benefit in the immediate estimation of EEG-activity changes.
