New insights
MIND.MEG is a non-invasive, quantitative way
to evaluate human brain function. It is a test to be used by qualified medical or qualified clinical professionals for the statistical evaluation of responses recorded from a magnetoencephalography (MEG) device as compared to a normative distribution of results.
Data Acquisition Setting
MIND.MEG is the analysis of the changes in human brain magnetic field from external stimuli by means of magnetoencephalography (MEG). Human electrical brain activity creates faint magnetic fields that MEG detects. MEG has been available for clinical use for decades, and now MIND.MEG has captured multi-dimensional and individual-specific features that separate normative and non-normative individuals.
Acquisition Format
The subject sits in a comfortable chair while the MEG device helmet covers the subject's head. The MEG protocol simply has the subject listen for an identical sound repeatedly while keeping her eyes closed. The subject merely needs to stay still and is sometimes distracted by a different sound
to help maintain focus.
Data Acquisition Duration
The subject is exposed to about 250 stimuli (epochs) sound tones,with loudness adjusted for the subject's hearing. The sound tones occur one every 2.5 seconds. The series of epochs (a run) lasts about 20 minutes, and after a 45 minute break there is a repeat 20 minute run. The entire data acquisition, including the break, takes about 1.5 hours.
Limitations
MIND.MEG has been analyzed only for elderly people. For the data to be useful, the subject must be able to lie reasonably still. The patient cannot be completely hearing impaired. If the subject has extensive dental hardware that cannot be removed, or other ferromagnetic metal in their bodies that interfere with the MEG signal, the data may also not be useful. The MEG protocol that is the basis
for MIND.MEG has been in use since at least 1999 and
there have been no reported side effects.
Why?
MIND.MEG has more than 15 different types of
measurements or dimensions; each of which is analyzed separately. Subjects with the same cognitive profile typically have very different MIND.MEG results. Yet the SAME subject's MIND.MEG result remains stable over a period of a few days.
