A recent 7 Tesla study provided evidence for the existence of resting state networks in the human spinal cord by demonstrating inter-subject reproducibility of temporal correlations between ventral (motor) gray matter horns and between dorsal (sensory) gray matter horns in healthy subjects. In this abstract we build upon these findings and present measurements of within-subject reproducibility of within-slice spinal cord functional connectivity between ventral horns and between dorsal horns. This work will be important for future studies that rely upon these measurements to gain insight into how these networks change due to aging, injury, or disease.
