(MEG) [ mag-ne″to-en-sef″ah-log´ra-fe] a noninvasive diagnostic technique that directly measures the magnetic fields produced by electrical currents in the brain. A vaultlike device is necessary to ensure that the accuracy of the test is not affected by interference from magnetic fields produced by electrical wires ...
WebThis technique measures the change in blood flow for activities (thought, experiences, action) in the brain. The nerve cells increase their consumption of oxygen when active. Blood hemoglobin releases oxygen to active nerve cells and has somewhat different magnetic properties when oxygenated than when deoxygenated. WebThe magnetoencephalogram (MEG) is a record of magnetic fields, measured outside the head, produced by electrical activity within the brain. Typically MEG sensors are housed …
