The MRI suite Superconducting Magnet RF Coil, Gradient Coil, Head/Surface Coil

What you’ll need apart from a MRI scanner Pulse sequence Stimulus presentation Peripheral recordings Advanced settings

Pulse sequence Contrast: T2* BOLD, ASL Scanning parameters: phase encoding direction, spatial resolution (slice thickness, in-plane resolution), slice orientation, temporal resolution, etc. Must be sensitive to the brain regions you’re trying to get signals from You’ll need to consult an MR physicist!

Stimulus presentation Visual Front/Rear Projection, MR-compatible LCD, Goggle Auditory Tactile Pain Olfaction
