Research MEG

Research MEG Facility

The Research Magnetoencephalography (MEG) Facility provides the SickKids Research Institute and local scientists access to a non-invasive functional neuroimaging technique that allows investigation of human brain activity on a millisecond timescale. The site is staffed with a full-time research technologist and supported by a booking clerk. An adjoining reception area, a change room, a bathroom, and a behavioural assessment room, shared with the Research MRI Facility, are available to researchers and participants. The facility is fully dedicated to research, complementing the clinical MEG lab also found at SickKids.

The facility operates a CTF cortical MEG system comprising 151 axial gradiometer sensors in a head-shaped helmet, with 29 additional reference sensors for environmental noise cancellation. Each sensor is a superconducting quantum interference device (SQUID), an extremely sensitive type of magnetometer which can measure the magnetic fields generated by the human brain. 

The facility was established through grant funding from the Canada Foundation for Innovation to the Centre for Brain and Mental Health (then called the Centre for Investigation of Neuroplasticity and Developmental Disorders), awarded in 2006, with the MEG system itself installed in 2010.

Services:

  • 151-channel cortical CTF MEG system with continuous head motion tracking, adjustable for supine or sitting position, located in a magnetically shielded room
  • Fully-integrated 64 channel EEG sub-system
  • Ancillary stimulus equipment: auditory (ear inserts or speaker), visual (projection), somatosensory (electrical or tactile)
  • Eye tracking
  • Audio/video monitoring and recording capabilities
  • Non-magnetic accessories: various response pads, prescription glasses (-5 to +3)
  • Workstations with various software for stimulus control, including Presentation, Matlab and PsychoPy

Hours of operation: Monday to Friday, 9:30 a.m. to 5 p.m.
