- Magnetoencephalography (MEG) is the recording of magnetic fields produced by electrical activity in the brain.
- Magnetocardiography (MCG) is the recording of magnetic fields produced by electrical activity in the heart.
- Neuromagnetism is a near synonym of MEG, meaning the study of neuronal activity by means of magnetic fields.
- Cardiomagnetism is a synonym of MCG.
- Transcranial Magnetic Stimulation (TMS) is magnetic stimulation of the brain through the skull. There is more TMS terminology on TMS pages.
- Near Infrared Optical Specroscopy (NIRS) is a new imaging method
that uses near infrared light.
- Magnetic source imaging (MSI) refers to studies
where the distribution of sources (or source current distributions) of
magnetic fields are determined on the basis of external measurements.
- Magnetic field tomography (MFT) is a
near-synonym of MSI. The intent here is to produce tomographic images
displaying neural electrical activity estimated on the basis of
measured magnetic fields.
- The SQUID (Superconducting QUantum
Interference Device) is the most sensitive detector of magnetic
fields. It is a superconducting ring that includes one or two
- A Josephson junction is a barrier for current
flow between two superconductors. It is usually made of an insulator,
but could also be a thin vacuum gap or a very narrow constriction in
- LORETA or Low Resolution Electromagnetic
Tomography is a term introduced by Pasqual-Marqui and Michel for their
method of solving the bioelectromagnetic inverse problem.
