To date, conventional echo planar imaging (EPI) based fMRI is the only method capable of providing real-time neurofeedback from a spatially specific ROI. Our research provides evidence that localized functional single-voxel proton spectroscopy (fSVPS) can be used as an alternative approach. We automatized and evaluated this new approach by running real-time fSVPS experiments on high (3 T) and ultra-high (7 T) magnetic fields. Overall, real-time water SVPS neurofeedback is a promising tool for studying and manipulating brain activity, which holds great promise for important scientific and clinical applications.
