Measurements of the brain's magnetic field, called magnetoencephalograms (MEG's), have been taken with a superconducting magnetometer in a heavily shielded room. This magnetometer has been adjusted to a much higher sensitivity than was previously attainable, and as a result MEG's can, for the first time, be taken directly, without noise averaging. MEG's are shown, simultaneously with the electroencephalogram (EEG), of the alpha rhythm of a normal subject and of the slow waves from an abnormal… 
Magnetoencephalography-theory, instrumentation, and applications to noninvasive studies of the working human brain
TLDR
The mathematical theory of the method is explained in detail, followed by a thorough description of MEG instrumentation, data analysis, and practical construction of multi-SQUID devices.
Magnetoencephalography in the study of epilepsy
Magnetoencephalography based on high-Tc superconductivity: a closer look into the brain?
TLDR
It is shown high-Tc SQUID-based MEG may be capable of providing novel information about brain activity due to the close proximity of the sensor to the head, and modulation of the occipital alpha rhythm and the mu rhythm found in the motor cortex is demonstrated.
Signal processing in magnetoencephalography.
TLDR
Methods for the interpretation of the MEG signals include the popular point current dipole, minimum norm methods, spatial filtering, beamformers, MUSIC, and Bayesian techniques, which are illustrated in examples of interictal epileptic spiking and voluntary hand-motor activity.
Magnetoencephalography ( Neuromagnetism )
The same fluctuating electrical currents from the brain that produce the electroencephalogram (EEG) also produce a magnetic field over the head, called a neuromagnetic field. A measurement of this
Overview of MEG
TLDR
The mapping of spatiotemporal patterns of activity within networks of cortical areas can provide useful information about the functional architecture of the brain related to sensory and cognitive processing, including language, memory, attention, and perception.
A NEW METHOD FOR MAGNETOENCEPHALOGRAPHY
TLDR
The MEG shows potential for noninvasively localizing some sources of epilepsy located deep in the brain and for straightforward functional imaging of brain activity in mind-brain investigations.
Impact of SQUIDs on functional imaging in neuroscience
This paper provides an overview on the basic principles and applications of magnetoencephalography (MEG), a technique that requires the use of many SQUIDs and thus represents one of the most
Measuring cerebral hemodynamics with a modified magnetoencephalography system
TLDR
The proposed forward model simulates the interaction of an applied magnetic field with changes in magnetic susceptibility in the brain associated with hemodynamics and demonstrates the potential and technical challenges of measuring cerebral hemodynamics with a modified MEG system.

Magnetocardiography of Direct Currents: S-T Segment and Baseline Shifts during Experimental Myocardial Infarction
TLDR
The magnetocardiograms showed both S-T segment shifts and direct currents as a result of infarction, however, they also showed that the S- T segment shifts were not produced by the direct currents.
Magnetoencephalography: Evidence of Magnetic Fields Produced by Alpha-Rhythm Currents
TLDR
Weak alternating magnetic fields outside the human scalp, produced by alpha-rhythm currents, are demonstrated and a course distribution shows left-right symmetry for the particular averaging technique used here.

TLDR
A magnetocardiographic chest map, consisting of the magnetic field plotted against time at various spatial positions, shows genteral QRS and T-wave structure, as in the electrocardiogram; this structure varies with spatial position.
