Spinal cord transfers bilateral motor and sensory
information between the brain and other extremities. The
structural and functional organizations of the white and
gray matters in both brain and spinal cord differ
remarkably. However, partly because of technical
challenges involved in spinal cord imaging, it is
largely unknown whether similar functional connectivity
exists and is detectable using functional MRI. Using
ultra-high filed (9.4T), we performed an ROI based
analysis of resting state BOLD MRI signals in
anesthetized monkeys. Our results support that there
exist differential intrinsic functional connectivity
networks within the primate spinal cord, which is
detectable and observable.
