Marmoset monkeys are an increasingly popular animal model for functional MRI studies due to their close homology with humans. To negate the confounds of anesthesia on brain activation, marmosets can be imaged awake. A restraint chair with an integrated receive array is described for minimizing motion during awake imaging. Motion was limited to 129 μm and 0.41°, allowing for comparable temporal SNR with respect to anesthetized imaging.
