title: [Peculiarities of cortico-cortical ipsilateral connections of the primary, secondary and tertiary sensomotor zones of cat cerebral cortex].
abstract: Relative distribution of the efferent association fibers of the primary motor--MI (area 4y), secondary--SMII (2pri) and tertiary--SMIII (area 5) sensomotor zones of cerebral cortex were studied in 30 cats using Nauta-Gigax method. The projection of insignificant number of associative fibers to the primary cortical sensory zone--CI (area 1,2, 3a, 3b) was demonstrated. Massive bilateral connections of MI with SMII (2pri) and SMIII (area 5) were shown. It was suggested that the restoration of the motor functions after local destruction of CMI, CMII and CMIII is due to the demonstrated multiple horizontal associative connections between the functional units of the mentioned sensomotor centers.
