[Changes in the amplitude of evoked potentials of the cerebral cortex and characteristics of the associated fast oscillations].
A permanent decrease of the primary response in the external layers of the rat somatosensory cortex was observed to be connected with a considerable increase of the response in deeper cortical layers (0.5 mm and more). Fast oscillations were recorded only in the upper cortical layers. They varied independently of the primary response and were absent under nembutal anesthesia. Fast  oscillations were more stable to the surface application  of potassium choride. A separate source of such oscillations is suggested
