<P>PROBLEM TO BE SOLVED: To correctly superimpose data by MEG (Magnetoencephalography) on MRI (Magnetic Resonance Imaging) images. <P>SOLUTION: A plurality of first markers 10 are attached to the head part of a subject. The imaging part of the bioinstrumentation apparatus images the brain in the state that the first markers 10 are attached and acquires MRI images for which the first markers 10 are projected. Second markers 20 are attached to the head part of the subject and generate a magnetic field by themselves. The magnetic field measurement part of the bioinstrumentation apparatus measures the strength of the magnetic field generated accompanying the nervous activity of the brain by SQUID (Superconducting Quantum Interference Device) in the state of attaching the second markers 29 at positions where the first markers 10 were attached. A part of the first markers 10 and the second markers 20 are formed so as to be inserted to an earhole. <P>COPYRIGHT: (C)2007,JPO&INPIT |
