Hands-on Brain-Computer Interfaces (BCI) Laboratory
ECBME 4090
Course description
The course, offered by the departments of Electrical Engineering, Computer Science, and Biomedical Engineering, provides hands on experience with basic neural interface technologies. Topics include recording EEG signals using data acquisition systems (noninvasive, scalp recordings), real time analysis and monitoring of brain responses, and analysis of intention and perception of external visual and audio signals.
