[Reorganization of the cortico-spinal tract after unilateral lesions of the neocortex].
By means of retrograde transport of horseradish peroxidase the left and right hemisphere connections of neocortex with right spinal cord in normal and 7-14 days after the left sensory-motor neocortex damage have been investigated. In normal brain the quantity of cross corticospinal projections was revealed. After the unilateral lesion of neocortex the atypical retrograde transport of HRP in neocortex of ipsilateral hemisphere has been observed. The role of collateral sprouting mechanisms in posttraumatic reorganization of the corticospinal tract has been discussed.
