Magnetoencephalography (MEG)


MEG is a neuroimaging technology for cognitive and clinical brain research that 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. However great potential exists to use MEG 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 perception and cognition: 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.). There are about 200 MEG centers worldwide. The MEG community is constantly contributing new methods and improving software tools to make the technique more accessible to a wider range of investigators.


The MEG Program @ McGill went live in 2012. Our mission is to provide state-of-the-art support and expertise to investigators interested in MEG as a tool for their cognitive and clinical neuroscience studies.


New! Introducing MEG-Infinity

The MEG-infinity program enables high-powered neuroscience research, encourages the adoption of open-science practices, and maximizes the impact of research funds. 

MEG-infinity offers unlimited 24/7 access to MEG scanning against the payment of a flat subscription fee (all prices in CAD), valid over a 6-month period: 

  • $12,000 for unlimited 24/7 access,
  • Open-science discount: $10,000 for unlimited 24/7 access, with direct deposit of the collected data in OMEGA, the Open MEG Archives,
  • $8,000 for unlimited after-hours access (5pm-08am) and weekends.

The subscription is for one study, with unlimited number of participants (cross-sectional design) and/or sessions (longitudinal design). The rates apply to MEG certified users who have been trained and approved to operate the system without assistance. The certification is permanent, and obtained with a 3x1-hour training program with MEG data collection for the investigator’s study ($500/hr). Certification fees will be waived until the end of December 2019 (a $1,500 value).    

An REB number and participant code are required at the time of booking. To get you started with data collection as soon as possible, if your study concerns resting state, basic sensory stimuli and tasks, you may proceed immediately with data collection using the OMEGA participant consent form, after verification of compliance by our team. Access to your data will be conditional to REB approval of your request to access the OMEGA repository.    

Current BIC cancellation policies apply, with special attention against booking-cancelling several blocks of time at once. 

Studies that require full assistance from our MEG staff remain at current rate ($500/hour). The discounted $400/hour rate for certified users who prefer to access on a case-by-case basis remains effective as well.   

We foresee that the MEG-infinity program will enable approaching exciting neuroscience questions concerning the neural dynamics of brain systems in health and disease with high-powered studies yielding robust results. We will experiment with MEG-infinity until the end of December 2019. Should this be a success, we may need to increase the subscription rates, so be opportunistic and enroll now! The rates are tailored to match the amount of seed funding readily granted for pilot studies out there (via e.g., BIC, CRBLM, QBIN, etc.).

Our team is here to provide all the support required for study design and data analytics.    

Please megatmcgill [at] (subject: MEG-infinity) (contact us) with any question. We'll be glad to get you started with the program.
