| Research Abstract |
In the mammalian spinal cord, Renshaw cells (RCs) are excited by axon collaterals of motoneurons, and in turn provide recurrent inhibition of MNs. However, a large part of the synaptic modulation of RCs during motor behaviors such as locomotion remains unclear. In this study, synaptic inputs to RCs in the lumbar segment during motor activity were examined. These results indicate that RCs are strongly inhibited by the spinal network during movements and the strength of the inhibition is related to the magnitude of the motor activity.
