Reconfiguration of the Spinal Interneuronal Network During Locomotion in Vertebrates

Frigon A. Reconfiguration of the spinal interneuronal network during locomotion in vertebrates. J Neurophysiol 101: 2201-2203, 2009. First published March 11, 2009; doi:10.1152/jn.00003.2009. Within the spinal cord, the vast network of excitatory and inhibitory interneurons must be functionally reconfigured on an ongoing basis during locomotion to adapt to the environment and meet particular demands of the task. It is clear that different rhythmic motor behaviors are generated by shared and specialized circuitry and that reconfiguration is governed by multiple inputs that dynamically interact at the spinal level.
