Magnetoencephalography (MEG) using superconducting quantum interference devices is well established in neuroscience with a potential for clinical applications. New magnetic field sensors allow to fundamentally change MEG setups, and these will allow close to natural behavior of subjects and patients during measurements. Optically pumped magnetometers (OPM) can be operated close to the scalp and as single sensors allow almost free movements of participants. Their drawback is increased requirements for magnetic background field suppression in magnetically shielded rooms. Here a proof of principle setup is discussed to reduce field fluctuations in the mHz range.
