Dual MEG systems

Child and Adult MEG DewarsMACCS currently operates two MEG systems, a 160 channel system for adult use and a 64 channel system for children.
Our 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 aluminum. The MSR was built by Fuhijira Co. Ltd. in May 2006. With the addition of the KIT child MEG system, our lab was the first in the world to house two MEG systems inside the same magnetically shielded room.

Child in MSRKIT/MACQUARIE 64-CHANNEL MEG SYSTEM (CHILD)

In July 2008, we installed a 64-channel MEG system, specially designed by AEL and Yokogawa to work with children.  

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.

Playroom

We have a 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.
