Spatial and Frequency Specific Artifact Reduction in Optically Pumped Magnetometer Recordings
Background: Magnetoencephalography (MEG) based on optically pumped magnetometers (OPMs) opens up new opportunities for brain research.However, OPM recordings are associated with artifacts.We describe a new artifact reduction method, frequency specific signal space classification (FSSSC), to improve the signal-to-noise ratio of OPM recordings.Method
