Studies of stimulus-evoked responses in single motoneurones in humans

Abstract

Surface electromyography (EMG) has been a powerful technique for studying reflex and other stimulus-evoked responses in the human nervous system. However, important additional insights can be gained into the operation of neural circuits by studying the responses of single motor units to various stimuli. In this paper, some of the advantages of single motor unit recording will be canvassed, and some examples of the application to this method to the study of reflex responses to sensory stimuli and brain stimulation will be presented.
