Technics and Potentialities of Intracranial Electrography

Abstract

Intracranial electrography is an extension of scalp and surface electro-encephalography in which electric impulses are obtained from the depths of the human brain. The surgical technic required for the placement of deep electrodes is simple, and the multi-contact electrodes are well tolerated. Pertinent information may be obtained by means of electric recording from or stimulation of the subcortex. This method portends to become a valuable diagnostic and investigative aid.
