摘要：The Magnetoencephalography (MEG) based on optically pumped magnetometers (OPMs) has emerged as a transformative wearable neuroimaging modality, offering significant advantages such as flexible sensor placement and closer proximity to neural sources. However, these very characteristics impose more stringent requirements on the environmental noise suppression. Among spatial filtering approaches, signal space projection (SSP) estimates the noise subspace directly from empty-room recordings and can be implemented without dense spatial sampling, detailed sensor-geometry modeling, or subject-specifi
