title: [Organization of neuronal responses in the sensomotor cortex during simultaneous stimulation of brain structures].
abstract: It has been found on alert non-immobilized rabbits that paired stimulations of the medical lemniscus, the midbrain reticular formation and the pyramidal tract in different succession cause in the sensorimotor cortex the formation of a temporary connection by the parameters of single unit activity and evoked potentials. The temporary connection is manifested in dynamics of evoked responses and in the change of electrical activity at the moment of usual presentation of the second stimulus, if it is omitted. The inflow of impulse activity by different paths adds some peculiarities to the organization of the temporary connection. The leading role in the given model situation may belong to the non-specific system.
