Brain activity likely to be involved in control of brain-computer interfaces (BCI) will be recorded by electroencephalography (EEG), a non-invasive technique. These recordings will be used to control a computer-based augmentative and alternative communication (AAC) device. The long-term goal is the advancement of BCI technology to provide access to AAC devices via brain activity alone, allowing individuals with severe neuromotor disorders to better engage in social interactions.
Participants may be asked to travel to the Speech and Applied Neuroscience Lab at the University of Kansas for up to 20 experimental sessions, or members of our team will meet them either at their home or medical institution. During these sessions, participants will be asked to attempt mouth and facial movements, produce (attempt, silently, or imagined) syllable sounds, and imagine performing other movements while brain activity is measured using a non-invasive EEG. During these sessions, participants will likely wear a cap with electrodes embedded that touch the scalp (EEG), and receive auditory and visual stimuli from an LCD monitor and headphones.
