MEG (Magnetoencephalography) is a neuroimaging technology for cognitive and clinical brain research. In a nutshell, MEG measures non-invasively the tiny magnetic fields generated by neuronal currents. A unique asset of MEG imaging is its unrivaled temporal resolution, reaching the millisecond time scale across the entire brain volume. On the clinical side, MEG has been typically indicated for the pre-surgical work-up of severe, drug-resistant epilepsy and the functional pre-surgical mapping of brain tumors. There is however great potential to use MEG as an instrument of choice to investigate other neurological syndromes and neuropsychiatric disorders (e.g., stroke, dementia, movement disorders, depression, etc.). Overall, MEG has strong value in revealing the dynamics of brain activity involved in subject’s perception, cognition and responses: it has provided unique insight on the time-resolved processes ruling brain functions (resting-state dynamics, language, motor control, visual and auditory perception, etc.) and dysfunctions (movement disorders, tinnitus, chronic pain, dementia, etc.).
[email protected] provides a full-suite of services related to MEG and MEG/EEG studies. This includes a variety of training programs for use of the MEG and related data acquisition and analysis software, Brainstorm.
A MEG session consists of the time necessary for MEG data acquisition in the instrument and does not include the duration for subject preparation. The time necessary for subject preparation varies from a minimum of 15 minutes for a MEG-only acquisition to 45 to 60 minutes when EEG needs to be acquired simultaneously with MEG.

Importation into Brainstorm (data analysis software package co-developed and supported by the MEG team; data is translated into Matlab file format). Integration of individual MRI (includes importation of original T1 volume, surface segmentation (head, skull, gray and white matter surfaces) and registration to MEG coordinate system). Alternatively, when no individual MRI data is available, a brain template can be warped to each subject's individual head shape, as digitized at the beginning of each session.
Data preparation: Artifact removal (C$50/hr of recording)
Artifact (heart beats, eye blinks) removal and marking of recording segments suspected of other artifact contamination (e.g., head movements)
Data preparation: Epoching and filtering (C$75/hr of recording)
Data epoching and filtering following the specifications provided by the investigator, averaging by condition with detection and rejection of 'bad trials’
Data Importation and Organization via Brainstorm (http://neuroimage.usc.edu/brainstorm/) also available - C$25/hr of recording
MEG source modeling using registration with structural MRI via Brainstorm (http://neuroimage.usc.edu/brainstorm/) - C$25/hr of recording
MEG Software Training Sessions
Investigators can obtain training on an individual basis or in small groups on the software used for MEG data analysis and imaging, including processing of MRI volumes and integration to the MEG data workflow. The sessions can host a maximum of 5 people at the investigator's desk or
at the MEG suite.
$500/day or $280/half-day for groups of 5
Brainstorm Training Courses
The best way to learn how to use Brainstorm, like any other academic software, is to benefit from local experts. However, you may be the first one in your institution to consider using Brainstorm for your research. We are happy to provide comprehensive online documentation and support through our forum but there is nothing better than a course to make your learning curve steeper. We organize courses for institutions who are willing to develop a user community for Brainstorm.
MEG Operator Certification allows a user to run studies themselves (24-7 access to the facility, Acquisition fees discount of 33%).
A. 2-hour training with the MEG System Manager to
cover aspects of subject safety, preservation of system integrity and general procedure for data acquisition
B. Attend 3 supervised recording sessions of his/her own study, supervised and assisted by the MEG System Manager. Last of the 3 sessions conducted without any assistance from the MEG System Manager
C. The MEG System Manager and the Director of MEG Research may require that additional training sessions are necessary for the investigator before obtaining certification
No additional cost beyond data acquisition rate.
