Abstract
Clinical electroencephalographic (EEG) records from the surface of the scalp represent only a small part of the electrical activities which are generated in the cortex. This is due to attenuations and distortions of the electrical signals by cerebrospinal fluid (CSF), meninges, bone, muscles, hair, etc. Therefore, for the study of generation mechanisms of the cortical EEG one has to approach the generators as closely as possible. In man this is possible only in exceptional situations such as neurosurgical operations, and therefore this problem has to be approached through animal experiments, which allow recording from the cortical surface and intracortically.
