Magnetoencephalography (MEG)

Baycrest is one of the few institutions in Canada with this type of technology that allows researchers to map a person’s brain activity while they are undergoing treatment.

Magnetoencepholography (MEG) is an imaging technique used to measure the small magnetic fields resulting from electrical activity in brain cells. Clinically, MEG may be used to detect and localize spiking activity in patients with epilepsy and in localizing brain regions involved in sensory processing and linguistic ability in surgical planning. In research, MEG is primarily used in the measurement of time courses of activity because of its high temporal resolution. MEG enables accurate pinpointing of sources in primary auditory, somatosensory and motor areas.

Visit the CTF Systems Inc website for more information about the MEG system and facilities available at Baycrest.

Baycrest also offers an MEG-compatible eye tracking system that enables the simultaneous collect of the respective data types.


The MEG (and EEG) equipment was obtained through the University of Toronto Functional Imaging Research Network (FIRN) with over $21 million of matched funding from the Canada Foundation for Innovation and the Ontario Innovations Trust. The Baycrest portion of this grant was over $3 million.
