Abstract

In this first monograph on the electro-encephalogram an attempt is made to cover all aspects of the clinical phases of the subject. A historical chapter includes the demonstration of electric currents in animal brains by Caton in 1875 as well as the subsequent contributions made in Germany, England and America, the literature being briefly reviewed. This is followed by a technical discussion of the principles of amplification and recording adapted at once to the purposes of the biologist setting up a laboratory and to those of the general reader.

The physical character of the alpha rhythm is discussed, brief attention being paid to its origin as argued by Adrian and by Berger. The physical characteristics of the beta rhythm, less well known, are given corresponding cursory treatment. Mention of delta waves completes the formal description. The phylogenic differences in rhythms, the development of the regular ten per second adult rhythm
