We have the ability to both sense our environment and make movements to interact with it. The sensory and motor regions of the brain interact with each other to make this possible. In addition, when we encounter changes in the environment (slippery floors, low lighting, etc.), we have a variety of sensory and motor adaptive processes that compensate and adjust to keep our movements accurate. To better understand how this happens, and how it might go wrong in patients with impaired movement, we study these processes and their neural bases in healthy people. Specifically, we use non-invasive brain stimulation (transcranial magnetic stimulation, or TMS) along with behavioral tasks involving pointing to targets in a virtual reality setup or reaching in a force field created with a robotic manipulandum.
