Motor learning involves changes in behavior through practice and has traditionally been associated with changes in the brain, i.e. plasticity, in brain regions that control movement. It is well established that sensory information is important for motor control, yet its role in learning has only recently been investigated. The primary purpose of this dissertation was to investigate the sensory processes associated with complex motor skill learning. In the first experiment, I demonstrated that motor learning was associated with an enhancement in proprioceptive sensitivity, or body position sense. In the second experiment, transcranial magnetic stimulation (TMS) was used to probe changes in sensory-motor networks of the brain. Motor skill training was associated with strengthening of sensory pathways to motor cortex. In the third experiment, inhibitory TMS was used to temporarily reduce activity in either the sensory cortex or cerebellum, two regions known to process proprioceptive information. Inhibitory stimulation over the sensory cortex impaired proprioceptive function with little effect on skill learning, while inhibiting the cerebellum reduced skill learning. Together, these experiments clarify the role of proprioception in motor skill learning, suggesting that position sense improves along with motor skill, and that sensory cortex and cerebellum play different roles in this process. This research extends our current understanding of the relationship between sensory processing and learning from basic movement paradigms to more complex skill learning. Overall, these findings have important implications for current models of motor control, and for individuals with sensory and motor deficits, such as stroke survivors.
