Abstract
Many studies have established a relationship between muscle afferent inputs or cutaneous inputs separately, and the excitability of alpha motor neurons. However, in normal physiological situations, more often these inputs coming from muscle spindles of agonist, antagonist or synergistic muscles operate simultaneously with mechanoreceptor inputs from the skin; besides, the behavior of the alpha motor neurons when they are being driven by supraspinal influences and otherwise, in the context of peripheral inputs, becomes of greater importance in terms of functional significance. In order to study this complex phenomenon, several experiments have been designed which may help in the better understanding of the physiology of alpha motor neurons during voluntary movements as well as in reflex activities.
