magnetoencephalography
Indications:
- epilepsy
Procedure:
- technique for mapping brain activity by recording magnetic fields produced by endogenous electrical currents in the brain
- magnetic field are detected with arrays of SQUIDs (superconducting quantum interference devices)
- records weak magnetic fields outside the human head
Clinical significance:
- provides millisecond-accurate information about neuronal currents supporting human brain function
- provides complementary information to electroencephalography
General
