We investigate how real-time feedback of brain signals can be used to help individuals with movement disorders. Using brain-computer interface (BCI) technology, our participants are able to use only their brain to control external effectors such as a robotic arm or an object in a virtual reality scene. For individuals with certain motor disorders (e.g., Parkinson’s Disease, focal dystonia, essential tremor), learning to use the BCI may induce plasticity that provides some recovery from symptoms. For individuals with severe disabilities due to central nervous system trauma or amyotrophic lateral sclerosis, the BCI may provide an alternative communication channel to restore some independence.
