This study demonstrates a novel rsfMRI application in the human spinal cord. The challenges and solutions were detailed. Reproducibility within and across subject was demonstrated. A major finding is that there were multiple prominent rsfMRI patterns in the spinal cord, showing lateral connectivity, unilateral connectivity and top-down connectivity. Future studies will improve spatial resolution, image the entire spinal cord, and map spinal cord connectivity to the brain, as well as explore clinical applications.
