Abstract
A magnetoencephalograph Mincludes: multiple pump-probe type optically pumped magnetometersA; a bias magnetic field forming coilfor applying a bias magnetic field in the same direction as a direction of pump light of each of the multiple pump-probe type optically pumped magnetometersA and in a direction approximately parallel to a scalp; a control devicethat determines a current for the bias magnetic field forming coil and outputs a control signal corresponding to the determined current; and a coil power supplythat outputs a current to the bias magnetic field forming coil in response to the control signal output from the control device.
