Motor-Imagery BCI with Low-Count of Optically Pumped Magnetometers

Brain-Computer Interface (BCI) is a system enabling direct communication between the brain and external devices. It has large potential in neurorehabilitation. New optically-pumped magnetometer (OPM)-based recording systems have large potential among noninvasive electroencephalographic and traditional magnetoencephalographic BCI-systems., that should be revealed., however. Here we demonstrated good performance of the hand-movement imagery BCI., built on low number of OPM-sensors.
