title: [Formation of postural asymmetry in rat hindlimbs during colchicine-induced unilateral blockade of axonal transport in cortico-lumbar projections].
abstract: The possibility of the formation of spinal cord functional asymmetry by the blockade of axonal transport in corticolumbar projections with colchicine was investigated. To identify the blockade of axonal transport, the method of retrograde transport of horseradish peroxidase was used. The blockade of axonal transport led to the formation of the asymmetric functional status of the spinal cord, manifesting in postural asymmetry of the hind limbs and characteristic changes in the pattern of bioelectrical activity of the flexor muscles. An endogenous factor inducing postural asymmetry in intact recipients was detected in the cerebrospinal fluid of colchicine treated animals. Based on the experimental data the conclusion is drawn that interruption of normal axonal transport attests to the destruction of central neurons.
