Professor Gandevia is an international leader in human neurophysiology. He has made findings of fundamental importance on the roles of intramuscular, joint and cutaneous sensory nerves in proprioceptive sensations and reflexes, and has shown the dependence of certain sensations on centrally-generated nerve discharges associated with command signals for movement. He was the first to show the fatigue resistance of human respiratory muscles, the rapid and powerful projection from cerebral cortex to the motoneurons of these muscles, and preservation of respiratory sensations when these muscles are completely paralysed.
