ELECTROENCEPHALOGRAPHIC STUDIES IN THE BRAIN SURGERY

Abstract

The clinical application of electroencephalography has gradually increased not only in psychiatry but also in neuro-surgery.
At the present time in the electroencephalographic studies many authors use Walter's apparatus, but such apparatus was unable to be manufactured in Japan during the wartime. So we used a simple apparatus, and studied the clinical changes of the E.E.G. in the case of brain-surgery. Especially I endeavoured to analyse these changes to explain the clinical meaning.
