title: Long loop reflexes: concepts and consequences.
abstract: New experimental results on long latency reflexes in human limb muscles were presented by neurophysiologists and clinicians with great experience in this field. The scope of presentations reached from the pattern of long latency reflexes in leg muscles during stance and the modifications in various motor disorders to the firing behavior of single motor units during torque perturbations of the elbow and to the role of habituation in long latency reflexes. Finally, the effect of stereoencephalotomy on long latency reflexes in normals and patients with parkinsonian tremor was reviewed.
