Migration of motor pool activity in the spinal cord reflects body mechanics in human locomotion.
During the evolution of bipedal modes of locomotion, a sequential rostrocaudal activation of trunk muscles due to the undulatory body movements was replaced by more complex and discrete bursts of activity. Nevertheless, the capacity for segmental rhythmogenesis and the rostrocaudal propagation of spinal cord activity has been conserved. In humans, motoneurons of different muscles are arranged i...
متن کاملEmergence of deletions during treadmill locomotion as a function of supraspinal and sensory inputs.
During locomotion, alternating activity of flexor and extensor muscles is largely regulated by a spinal neuronal network, the central pattern generator, the activity of which is modulated by peripheral and supraspinal inputs. In the absence of these modulatory inputs, for example during fictive locomotion after spinalization and curarization, spontaneous failures of motor activation (deletions)...
متن کاملTissue PO2 and the effects of hypoxia on the generation of locomotor-like activity in the in vitro spinal cord of the neonatal mouse.
The neonatal mouse en bloc spinal cord-brainstem preparation used in combination with advances in mouse genomics provides a novel strategy for studying the spinal control of locomotion. How well the mouse en bloc preparation is oxygenated however, is unknown. This is an important consideration given that (a) other superfused mammalian en bloc preparations have anoxic cores and (b) hypoxia can h...
متن کاملChondroitinase ABC Administration in Locomotion Recovery After Spinal Cord Injury: A Systematic Review and Meta-analysis
Introduction: The present systematic review and meta-analysis aims to conduct a comprehensive and complete search of electronic resources to investigate the role of administrating Chondroitinase ABC (ChABC) in improving complications following Spinal Cord Injuries (SCI). Methods: MEDLINE, Embase, Scopus, and Web of Sciences databases were searched until the end of 2019. Two independent reviewe...
متن کاملO2: Flaxseed Reduces Proinflammatory Factors IL-1β, IL-18 and TNF-α in Injured Spinal Cord Rat Model
The pathophysiology of acute spinal cord injury (SCI) involves primary and secondary mechanisms of injury. Secondary injury mechanisms include inflammation, oxidative stress. The secondary inflammation of spinal cord tissue after SCI was critical for the survival of motor neuron and functional recovery. Flaxseed is a rich source of lignan phytoestrogen, α-linolenic acid. Flaxseed has rema...
