[Afferent connections of the nuclei of dorsal columns of spinal cord].

The authors studied structural origins of the conduction of the dorsal chord afferent projections to contralateral dorsal column nucleus in cats, which were discovered after foreleg electrical stimulation by the evoked responses method. This evoked responses remain after unilateral section of the medial lemniscus. It was shown the existence of not classical connections which cross to another side at the level of spinal cord and caudal division of brain stem. The discovery fibres contact with other projection systems and form all known types of interneuronal contacts.
