3T MRI

Magnetic resonance imaging (MRI) is a powerful tool widely used in neuroimaging owing to its non-invasive nature and high sensitivity to brain activation. The workhorse of present-day cognitive neuroimaging research, the 3T MRI scanner provides excellent image quality for routine data collection to study brain activation, anatomy, and metabolism. Additionally, the Spinoza Centre houses an integrated recording system that registers several important physiological parameters into the standard workflow.

Scanning protocols include methods for

• measuring brain activation
• (quantitative) anatomical imaging
• probing white matter structure (using diffusion-weighted imaging)
• neurochemical profiling (using proton spectroscopy)

Equipment for monitoring additional processes during scanning includes

• cardiac and respiratory cycles
• eye movements and eye tracking
• electromyography (EMG) and skin conductance (GSR)

Advanced stimulus presentation and behavioural recording is possible with

• Cambridge Research Systems 32-inch LCD screen for visual presentation
• Current Designs fiber-optic response package with various response devices
• MR confon audio system
• Digitimer electrical current stimulation
• 256-channel MRI compatible EEG system
