Soleus motoneurone excitability in man: an indirect approach for obtaining quantitative data.

A J McComas, M Mirsky, F Velho, A Struppler.   

Abstract

Using combinations of H and T reflexes, spatial summation has been studied in the human soleus motoneurone pool. With certain assumptions, mathematical treatment of the results yielded estimates of the thresholds of motoneurones to monosynaptic activation by Ia nerve fibres. It was found that, on average, about 62 EPSPs were required to discharge a motoneurone and that a single Ia fibre supplied about 139 neurones.
