| contents | This study presents an analysis of sensorimotor rhythms using an advanced, optically-pumped magnetoencephalography (OPM-MEG) system - a novel and rapidly developing technology. We conducted real-movement and motor imagery experiments with nine participants across two distinct magnetically-shielded environments: one featuring an analog active suppression system and the other a digital implementation. Our findings demonstrate that, under optimal recording conditions, OPM sensors provide highly informative signals, suitable for use in practical motor imagery brain-computer interface (BCI) applications. We further examine the feasibility of a portable, low-sensor-count OPM-based BCI under varied experimental setups, highlighting its potential for real-time control of external devices via user intentions. |
