A fresh look at propriospinal interneurons plasticity and intraspinal circuits remodeling after spinal cord injury

Spinal cord injury (SCI) disrupts communication between the brain-derived descending commands and the intraspinal circuits, the central pattern generator (CPG), that execute movements. Dynamic changes in the interaction of the brain-spinal cord as well as in structure-function relationships play a v...

description Spinal cord injury (SCI) disrupts communication between the brain-derived descending commands and the intraspinal circuits, the central pattern generator (CPG), that execute movements. Dynamic changes in the interaction of the brain-spinal cord as well as in structure-function relationships play a vital role in the determination of neurological function restoration. These changes also have important clinical implications for the treatment of patients with SCI. After SCI, at both brain and spinal cord levels, detour circuits formation and neuronal plasticity have been linked to functional improvement under the condition of spontaneous recovery as well as electrical stimulation- and rehabilitative training-assisted recovery. The principles governing neural circuit remodeling and the neuronal subtypes specifically involved during the recovery from SCI are largely unknown. In the present review, we focus on how multi-level neural circuits are reconstructed after SCI. We highlight some new studies using rodent and zebrafish SCI models that describe how the intraspinal detour circuits are reconstructed and the important roles of spinal excitatory interneurons.
