A device has been described which is capable of converting standard EEG records into digital or numerical form so that these figures may be operated on by electronic computers. The device scans up to eight channels of EEG records, measures the amplitude of the record at 0.5 mm intervals and presents the digital data in printed form as well as on computer tape. The accuracy and limitations of the device are described.

    ABSTRACT: The amplitude probability density functions of various synthetic waveforms and normal alpha activity have been determined using digital computer techniques. The amplitude probability densities of alpha activity in the subjects tested were Gaussian and the envelope amplitude probaility ability densities showed a Rayleigh form. These findings suggest that alpha activity may have analogous characteristics to noise after passage through a narrow-band filter.

    ABSTRACT: A method is described for the conversion of EEG records to digital form by the use of standard laboratory instruments and a photo-cell scanner. The converter scans the EEG trace, measures the height of the trace at 0.6 mm intervals and records the digital values as printed three digit numbers.

    ABSTRACT: Computer analyses of clinical electroencephalographic (EEG) ink tracings, which were reconverted to their electrical form with the aid of a newly developed multichannel automatic curve reader, are illustrated. On-line and off-line (via the intermediary of a magnetic tape recording) analyses by a variety of methods (frequency analysis, autocorrelation and crosscorrelation, and averaging of EEG responses evoked by sensory stimulation) were made of EEG tracings (some recorded 16 years previously) from a variety of different clinical conditions. Comparison, in some instances, of the data obtained by means of the curve reader with those computed from a magnetic tape recording made simultaneously with the original ink recording showed that the results of the two were essentially indistinguishable, within the limitations of the frequency response of the original ink tracing, and that of the scanning principle of the curve reader.
