title: [Effect of early mass training in food mazes on evoked potentials of the sensomotor cortex and caudate nucleus in the rat].
abstract: The data obtained attest that not only prolonged (three months) motor training of rats in a tretbahn, but also mass alimentary-motivated training in mazes at the same period of postnatal ontogenesis and of the same duration is attended with enhanced activity of the sensorimotor cortex as manifested in the reduction of evoked potential latencies. Such enhancement was more pronounced after training in mazes than in a tretbahn. Mass alimentary-motivated training of rats in mazes resulted in shorter latencies of the caudate nucleus EP to peripheral stimulation, which testifies to a close functional connection of this striatum structure with the sensorimotor cortex in formation of plastic reorganizations in an enriched sensory medium.
