MEG as a Medical Diagnostic Tool in the Greek Population

Abstract

Magnetoencephalography (MEG) is the recording of the magnetic field produced by the flowing of ions in the brain. This article reports our experience in the application of MEG in patients and healthy volunteers in the Greek population. We provide a brief description of our research work. The MEG data were recorded in a magnetically shielded room with a whole-head 122 channel or an one-channel biomagnetometer. Our results lead us to believe that the MEG is an important research field which is evolving quickly with a number of interesting findings with respect to normal and abnormal functions of the human brain. It could provide clinical practice with an easy to perform non invasive method, which could be adjunct to conventional methods for the evaluation of brain disorders.

The Influence of Magnetic Fields, Including the Planetary Magnetic Field, on Complex Life Forms: How Do Biological Systems Function in This Field and in Electromagnetic Fields?

“…As discussed earlier, the functioning of the brain leads to the generation of electromagnetic fields that can be measured by techniques such as SQUID or magnetoencephalogram (MEG) (reviewed in [67,138]). Such techniques can be used for both fetal [139] and adult [140] brain assessment. As such, these techniques can be used to detect neurological issues during development and during aging when loss of neurological integrity can occur with some frequency.…”

The Influence of Magnetic Fields including the Geomagnetic Field of Earth on Complex Life Forms: A Silent “Partner” in Human Health and Disease?

“…As discussed earlier, functioning of the brain leads to the generation of electromagnetic fields that can be measured by techniques such as SQUID or magnetoencephalogram (MEG) [reviewed in 65,135]. Such techniques can be used for both fetal [136] and adult [137] brain assessment. As such, these techniques can be used to detect neurological issues during development and during aging when loss of neurological integrity can occur with some frequency.…”

Frequency Analysis for The Effect of Pico Tesla-Transcranial Magnetic Stimulation in Epilepsy Patients Using Magnetoencephalography

“…Transcranial magnetic stimulation (TMS) is noninvasive and easy to perform method without direct contact with the underlying skin and has been used to investigate a variety of clinical conditions 1 . Its magnetic field strength is about 1.5 to 2 Tesla at the surface of the coil and drops off exponentially with distance from it.…”

“…It is designed to create pT-TMS range modulations of magnetic flux in the alpha frequency range (8-13Hz) of every patient. The pT-TMS device was configured for each individual to produce a square wave (so as to resemble the firing activity of neurons in the brain) [7][8][9][10][11][12] .…”
