[Interaction between spindles evoked by electric stimulation of different regions of the cerebral cortex]. 1977

S P Narikashvili, and D V Kadzhaia, and A S Timchenko, and M S Narikashvili

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.

D010424	Pentobarbital	A short-acting barbiturate that is effective as a sedative and hypnotic (but not as an anti-anxiety) agent and is usually given orally. It is prescribed more frequently for sleep induction than for sedation but, like similar agents, may lose its effectiveness by the second week of continued administration.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D002540	Cerebral Cortex	The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulci. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.

D005071	Evoked Potentials	Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.
