Brain-computer interfaces (BCIs) aim to provide a means of communicating and interacting with one's environment in the absence of conventional motor pathways. This project involves exploration of the neurophysiology underlying SMR-based BCI use, using a form of noninvasive brain stimulation, TMS, to perturb specific neural circuits. The project will mainly involve analysis of EEG data from experiments with human subjects, and may also include helping to run experiments, and developing/validating alternate BCI task paradigms.
