Abstract

This research sought to investigate the role of the Renshaw Cell with respect to transient motoneuron firing. By studying the cat motoneuron and Renshaw Cell, which interact to form recurrent inhibition, several low order lumped parameter models were developed that simulate known characteristics of the injected input current vs. firing rate phenomena. The neuron models, in the Renshaw Cell inhibition configuration, were tuned to fit experimental data from cat motoneurons. Results of the simulation indicate that the motoneuron itself porvides the adaptation seen in its firing rate and the Renshaw Cell's role may be primarily to fine-tune the motoneuron's adaptation process.
