Neurophysiology

Dr. Marcus Devanandan established the Neurophysiology Laboratory in 1975. The main focus here has been the structure and function of the primate and human hand. Applying anatomical and physiological techniques, especially with tracers such as horseradish peroxidase (transynaptic labeling of cells) and fluorescent dyes, the sensori-motor system has been studied at the peripheral, spinal and cerebral cortical levels to understand the organization of the hand. He suggested that the lumbrical muscle has a major sensory role in proprioception. Work on innervations of finger joints is cited in Gray’s Anatomy.
