The MindCORE Neuroimaging Facility houses a state of the art Siemens Cima.X 3.0T MRI scanner (XA61 software version), which is equipped with Gemini Gradients. These advanced gradients have the highest commercially available gradient strenth in a whole-body scanner (200 mT/m at 200 T/m/s). The Cima.X scanner is equipped with scan sequences including: simultaneous multi-slice (AKA multi-band), RESOLVE, HASTE, and ZOOMit for performing functional, structural, diffusion, and ASL imaging. Available coils include 20-, 32-, and 64-channel head coils, large and small flex coils, and a spine coil. The MRI scanner bore is 60 cm.

The scanner room is equipped with MR-compatible behavioral equipment including: a BOLDscreeen 32 monitor (Cambridge Research System), a fiber optic response system (Current Designs) including button box and joystick, both in-ear (Sensimetrics model S14) and over-the-ear headphones, and an eye tracking system (Eyelink 1000). The Facility will provide a fiber optic microphone (Optoacoustics FOMRI-III) with adaptive noise cancelling capabilities. The microphone features perpendicual dual channels; response frequencies from 50-20,000 Hz; maximum sound pressure level (SPL) 130 dB SPL; less than 1% total harmonic distortion at 94 dB SPL; sampling frequencies of either 8,000 or 16,000 Hz; and latencies as low as 16 ms. Post-processing software (OptiMRI) performs real-time speech enhancement using noise reduction algorithms optimized for acoustic MRI characteristics. Stimuli may be presented using either a dedicated stimulus presentation computer equipped with Psychtoolbox for Matlab and PsychoPy or with a researcher-supplied laptop.

The Facility also houses a participant changing room with secure lockers, a waiting room for participants and those accompanying them, behavioral testing rooms, a mock MRI scanner, and a conference room. The Facility Director’s office is located in the Facility space.
