Three MEG systems

The Department of Cognitive Science currently manages three MEG systems, a 160 channel system for adults, a 108 channel system for children, and a system designed for patients with cochlear implants or hearing devices.

Our adult and child MEG systems are housed in a magnetically shielded room or MSR. It consists of three layers of permalloy (an alloy of iron and zinc), and one layer of copper. The room frame is made of aluminium. The Hearing MEG system is housed in a second MSR. These MSRs were built by Japanese specialist companies: Fuhijira Co. Ltd and Ohtama Co. Ltd. With the addition of the KIT child MEG system, this lab was the first in the world to house two MEG systems inside the same magnetically shielded room. Since moving to the Australian Hearing Hub in 2013, the lab now houses three custom built MEG systems.

In 2006, we installed a 160-channel MEG system, funded by an ARC Linkage-Infrastructure, Equipment and Facilities Grant.

Child in MSRKIT/Macquarie 125-Channel MEG System (Child)

In 2008, we installed a 125-channel MEG system, specially designed by Kanazawa Institute of Technology AEL and Yokogawa to work with children funded by an ARC Linkage Industrial Partner Grant. In 2013, KIT upgraded the system and added 48 additional channels. In 2014, we installed a Real Time Head Movement System (ReTHM), so that errors from head movements can be cancelled out.

 

 

 

Hearing MEG SystemKIT/Macquarie Hearing MEG System

In 2013, we installed a custom built MEG system, specially designed by AEL to investigate brain function in patients with cochlear impants and hearing devices. This was funded in collboration with Macquarie University, and The HEARing CRC, including Cochlear Limited.

Helium Recovery SystemHelium Recovery System

In 2013, the ARC Centre of Excellence in Cognition and its Disorders, in collaboration with CSIRO, installed a helium recovery system. This project developed a system to recover the helium gas that boils off during MEG operation, and converts the gas back into liquid helium. This project received funding from the New South Wales Science Leveraging Fund, along with funding for the CCD from Macquarie University.

Other equipment

EEG

We currently use a Brain Products 63 channel MEG-compatible EEG system, with MEG-compatible 63 channel Fast 'n' Easy EEG caps from EASYCAP.

Polygraphic

We have BrainProducts MEG-compatible polygraphic system with eight channels of EMG and eight polygraphic channels (GSR, respiration, etc.).

Eyetracking

We have an Eyelink 1000 remote MEG-compatible eyetracker system.

Projector

An InFocus IN5108 projector allows resolutions of up to 1600 x 1200 to be projected at a vertical sync rate of up to 120Hz, with a brightness of 4000 Lumens. This unit also allows for the adjustment of both vertical and horizontal keystoning.

Earphones

Auditory stimuli are delivered by a set of Etymotics E30 earphones. We also have a tubephone system custom designed by National Acoustics Laboratory for language research with a frequency response greater than 9 kHz.

Proceedings of 20th International Congress on Acoustics, ICA 2010, Sydney, Australia, 23-27 August 2010.)

Simulator and Playroom

We have a MEG simulator room and dedicated playroom for our child participants and any siblings that may come along on the day. This room is also available for parents to use while waiting for their child to finish testing.

New MEG Project Proposal form

All MEG projects are considerd by the MEG Executive Committee and applications are provided with feedback on their proposed project. Please download the MEG research plan form and send it to Dr Jon Brock for consideration.
