## Indications for use
Elekta Neuromag® with MaxFilter TM non-invasively measures the magnetoencephalographic (MEG) signals (and, optionally, electroencephalographic (EEC) signals) produced by electrically active tissue of the brain. These signals are recorded by a computerized data acquisition system, displayed and may then be interpreted by trained physicians to help localize these active areas. The locations may then be correlated with anatomical information of the brain. MEG is routinely used to identify the locations of visual, auditory. somatosensory, and motor cortex in the brain when used in conjunction with evoked response averaging devices. MEG is also used to non-invasively locate regions of epileptic activity within the brain. The localization infornation provided by MEG may be used, in conjunction with other diagnostic data, in neurosurgical planning.
