An approach to visualization of active position in brain by MEG

Reports a way to visualize the active position of the brain, and an improvement method to estimate the dipole of the MEG (magnetoencephalogram), which is the central part of the activation. In the past, at the Medical School of Osaka University, a method was used where an early-stage position was set manually and only its neighborhood was searched, but that method is less precise. On the other hand, our new method automatically estimates the dipole position and its moment for all positions of the brain. As a result, the measurement accuracy of the dipole position and moment was improved, and the position and moment derived from this calculation is medically adequate
