This manual presents concise definitions of, and directions for recording, an electroencephalogram.
Terms are defined so clearly that a person ignorant of the subject of electricity will have no difficulty in understanding the basic terminology and functions of such subjects as resistors, condensors, vacuum tubes, and wave forms.
Brain structure and physiology are simply, but adequately, described and are related to the electroencephalogram. The significance of frequency, amplitude, and wave forms in normal and abnormal activity are discussed and illustrated. The varieties of artifacts that occur are illustrated, and their source and methods of correcting for them are described. The sections "Recording on the Electroencephalograph" and "Physiologic and Pharmacologic Factors Affecting the Electroencephalogram" are adequate for the beginning electroencephalographer and suggest further reading.
The chapter on seizures briefly discusses various types of patients and illustrates the EEG patterns commonly associated with each. Suggested conduct of the technician in caring for
