Synaptic plasticity modulates the spontaneous recovery of locomotion after spinal cord hemisection

Conversely, neither the expression levels of synapsin-I nor the locomotor recovery were associated with the expression of brain-derived neurotrophic factor. Overall results indicate that after spinal cord hemisection, substantial recovery of hindlimb locomotion could occur spontaneously, and that synaptic plasticity within spinal circuitries below the level of the lesion, could be an important mechanism involved in these processes.
