CFMI offers over 1,000 square feet of dedicated office and testing space, designed to support a wide range of research activities. Amenities include a semi-private waiting area, a single-use restroom, a kitchenette, and a conference room for meetings or collaborative work. The facility houses two behavioral testing rooms available for users engaged in scanning studies. The first, known as the “Behavioral Room,” features a mock scanner to support preparatory sessions. The second, the “NIRS Room,” includes a two-room layout with adaptable seating arrangements, enabling on-site neuromodulation.
