The subject of this article is detection of brain magnetic fields, or magnetoencephalography
(MEG). The brain fields are many orders of magnitude smaller than the environmental …

Electrophysiological activity in the human brain generates a small magnetic field from the
spatial superposition of individual neuronal source currents. At a distance of about 15 mm …

Use of SQUIDs for stationary magnetic field detection (eg, in MagnetoEncephaloGraphy,
MEG) is discussed. Such devices operate in the presence of environmental noise and must …

The brain's magnetic signals are much weaker than the magnetic disturbances inside the
typical commercial magnetically-shielded room. Magnetic noise arises from far-field …

Magnetoencephalography (MEG) is a noninvasive technique for investigating neuronal
activity in the living human brain. The time resolution of the method is better than 1 ms and …

At present, one of the most promising windows to the functional organization of the human
brain is magnetoencephalography (MEG). By mapping the magnetic field distribution …

Magnetoencephalography (MEG), an invaluable functional brain imaging technique,
provides direct, real-time monitoring of neuronal activity which is necessary for gaining …

The spatial response of the magnetoencephalogram (MEG) to sources in the brain's cortex
is compared with that of the electroencephalogram (EEG). This is done using computer …

For a dipole source, theory predicts 3 useful differences between the MEG and EEG spatial
patterns over the head. These are seen when a comparison is made between theoretical …

Magnetoencephalography (MEG) is an exciting brain imaging technology that allows real-
time tracking of neural activity, making it an invaluable tool for advancing our understanding …
