Disease relevance of Magnetoencephalography


Psychiatry related information on Magnetoencephalography


High impact information on Magnetoencephalography

  • A discussion of the instrumentation based on the superconducting quantum interference device that is used for detecting the magnetic field distribution, the analytical techniques, current research, and future directions of magnetoencephalography in epilepsy research is presented [6].
  • On the basis of the assumption that use-dependent reorganization in these networks contributes to the fundamental abnormalities seen in focal dystonia, we treated 10 affected musicians and measured the concomitant somatosensory changes by using whole-head magnetoencephalography [7].
  • Predictions regarding amplitudes and latencies of cortical responses (M300, the magnetic counterpart to the P300) to targets were tested by investigating the neurophysiological effects of the post-T1 item (mask) by means of magnetoencephalography (MEG) [8].
  • We measured, with whole-scalp magnetoencephalography, evoked fields from 10 healthy subjects to 1-ms thulium-laser stimuli that selectively activated nociceptive nerve fibers [9].
  • In this Letter we point out that synchronization analysis techniques can detect spurious synchronization, if they are fed with a superposition of signals such as in electroencephalography or magnetoencephalography data [10].

Biological context of Magnetoencephalography


Anatomical context of Magnetoencephalography

  • Propagation of the neuronal population of the interictal epileptic spike was quantified in 5 patients with complex partial epilepsy arising from temporal lobe using electroencephalography and magnetoencephalography [13].
  • This is the first study to clarify the primary cortical processing of second pain by magnetoencephalography, through the selective activation of C-fibers, by the stimulation of a tiny area of skin with a CO2 laser [14].
  • We report five patients with rolandic epilepsy associated with giant somatosensory responses to median nerve stimulation, in whom we analyzed the pathophysiologic relationship between rolandic discharges and the somatosensory responses using magnetoencephalography [15].

Associations of Magnetoencephalography with chemical compounds

  • In the present study, we further investigated whether treatment with acamprosate could attenuate the post-alcohol withdrawal hyperexcitability or hyperarousal in humans using brain magnetoencephalography mapping of spontaneous fields [16].
  • METHODS: Neuronal magnetic fields, evoked by electrical stimuli to the thumb and/or to the index finger of the right hand, were recorded in different hand postures ('OPEN': opened hand and 'CLOSE': both fingers in opposite position to pick up something) by using a whole head type magnetoencephalography [17].
  • The effect of oral administration of sodium valproate in normal subjects was evaluated using whole-scalp magnetoencephalography, with results compared to the effect of sodium valproate in photosensitive children [18].

Gene context of Magnetoencephalography

  • Two cases (a young male and a girl, suffering intractable epilepsy) of diffuse subcortical laminar heterotopia, or so-called double cortex (DC) have been investigated using magnetoencephalography (MEG) [19].
  • The combined temporal and spatial resolution of MEG (magnetoencephalography) was used to study whether the same brain areas are similarly engaged in reading comprehension in normal and developmentally dyslexic adults [20].
  • Theta oscillations and human navigation: a magnetoencephalography study [21].
  • In the present study, we investigated the generators of nogo potentials by recording ERPs and by using magnetoencephalography (MEG) simultaneously during somatosensory go/nogo tasks to elucidate the regions involved in generating nogo potentials [22].
  • Using magnetoencephalography (MEG) we recorded responses in SI and SII in eight healthy humans to four different intensities of selectively nociceptive laser stimuli delivered to the dorsum of the right hand [23].
