EEG-Based Brain-Computer Interface

The rise of new technologies allows people living with ALS to access the computer using alternate methods. One alternative access and communication method is an electroencephalographic (EEG)-based brain-computer interface (BCI). The EEG-based BCI allows individuals with ALS to communicate using a computer even when other conventional devices have failed, as the system is independent of neuromuscular activity. By turning EEG (brain wave) signals detected from the scalp into an electrical instruction, the BCI allows people to make selections from a computer screen.
 
We are currently collaborating with the Wadsworth Center in Albany, New York in a study funded by the NIH. The study is intended to evaluate both the complexity of the system and the degree to which each participant will be able to communicate. Trials consist of asking the subject to follow a series of simple instructions and to complete certain tasks while using the BCI. The ultimate goal of the study is to develop a practical home based system.
