A sensory feedback control model of neuromuscular systems

We have developed a computer model to examine the inter-working relationships between Renshaw cell recurrent inhibition of /spl alpha/-motoneurons and /spl beta/-motoneuron innervation of spindle intrafusal muscles, two of the several feedback pathways modulating muscle force generation. To restore motor function after paralysis or injury is to restore coordinated control of muscle force generation. A better understanding of interactions among those neural circuits in the spinal cord that directly regulate recruitment of /spl alpha/-motoneurons is crucial for achieving the noble goal of restoring motor function for paralyzed people.
