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.
