[Interaction between spindles evoked by electric stimulation of different regions of the cerebral cortex]. / K vzaimodistviiu vereten, vyzvannykh élektricheskim razdrazheniem raznykh oblastei kory bol'shikh polusharii golovnogo mozga

In unanesthetized immobilized cats, under repeated administration of small doses of nembutal (2-3 mg/kg), connections between the projection and the parietal associatition cortical areas was studied as well as the interaction between spindles elicited by stimulation of these areas. Stimulation of the primary sensory areas (auditory or somatosensory) was shown to be able to elicit spindles not only in the stimulated area but in the association cortex too. This latter spindle, being kind of induced from the sensory areas, interacts with the spindles elicited by the direct electrical stimulation on the association cortex.
