High-resolution EEG (HR-EEG) and magnetoencephalography (MEG)
Neurophysiologie Clinique, 2015High-resolution EEG (HR-EEG) and magnetoencephalography (MEG) allow the recording of spontaneous or evoked electromagnetic brain activity with excellent temporal resolution. Data must be recorded with high temporal resolution (sampling rate) and high spatial resolution (number of channels).

Magnetoencephalography (MEG) as a tool to investigate the neurophysiology of autism
, 2011 This chapter introduces a modern functional neuroimaging method, magnetoencephalography (MEG), and addresses how this technique is being applied to study dynamic brain actvity and neural processing in ...

Magnetoencephalography (MEG) and Magnetic Source Imaging (MSI)
The Neurologist, 2004Real-time, direct assessment of brain electrophysiology is critical for noninvasive functional mapping and for the identification of paroxysmal epileptiform abnormalities in the evaluation of patients for epilepsy surgery. Historically, electroencephalography (EEG) and evoked potentials (EPs) have performed these functions. However, both often required

Magnetoencephalography (MEG) and other neurophysiological investigations
2013Cortical generators of epileptic and certain physiological activity can be localized noninvasively by magnetoencephalography (MEG). MEG detects weak magnetic fields produced by the postsynaptic currents of pyramidal cortical cells in sulcal walls. Unlike EEG, MEG signals are not distorted by edema or bone defects, and unlike fMRI, abnormal hemodynamics

Localisation of Epileptic Foci with Multichannel Magnetoencephalography, MEG
1995With the development of multichannel magnetoencephalographs biomagnetic signals can be recorded over large areas at the same time. It allows determination of the magnetic field outside the head generated by spontaneous epileptic discharges. From the maxima of outward and inward magnetic fluxes the locations of the sources of epileptic discharges can be

Evaluation of neuronal effects of electroconvulsive therapy by magnetoencephalography (MEG)
Progress in Neuro-Psychopharmacology and Biological Psychiatry, 20001. Interictal spontaneous MEG was investigated in five male patients with major depressive disorder (according to DSM IV) treated with right hemispheric ECT over a period of five weeks. Spontaneous MEG-activity was also recorded in five male patients treated with tricyclic antidepressants during the same time period. 2. The analysis of slow (0-7Hz) and

Magnetoencephalography (MEG) in Epilepsy Surgery
1997Whole-scalp MEG has proved to be a suitable tool for preoperative evaluation of patients suffering from drug-resistant focal epilepsy. MEG recordings are non-invasive and safe for the subject, and no demanding preparations of the patient are needed before measurement. The MEG recordings may reveal several epileptic foci, and the order of activation can

Frontier and hot topics in Magnetoencephalography(MEG) in neurological diseases
Neurological SciencesMagnetoencephalography (MEG), a non-invasive neuroimaging technique with millisecond temporal resolution and millimeter spatial resolution, is an essential tool for investigating neurological disorders. This study conducted a systematic analysis of 4,040 relevant publications from the Web of Science database (2000-2024) using VOSviewer and CiteSpace to

[Functional imaging of the brain. Magnetoencephalography (MEG)].
Der Radiologe, 1994Magnetencephalography (MEG) is a new diagnostic tool for the exact localization of the biomagnetic sources of the electrical activity of the brain. The extremely weak magnetic fields are generated by the postsynaptic activity of the neurons, acting like current dipoles. They are measured with a SQUID (superconducting quantum interference device).
