Abstract
Superconductors are expected to achieve perfect magnetic shielding, which will be useful for studies on neural activities of the brain especially in the lower frequency range down to DC. Operating in the environment of other noisy instruments and/or interference such as subways, cars, etc. will be available. Instead of gradiometers, higher sensitivity magnetometers are effective in the low noise space, which will allow detections of signals from deeper and/or weaker magnetic sources with a higher S/N ratio.
