Intrinsic functional architecture of the non-human primate spinal cord derived from fMRI and electrophysiology

Abstract

Resting-state fMRI shows networks of correlated activity in the spinal cord, similar to those in the brain, but whether fMRI is a valid measure of functional connectivity in spinal cord is unclear. Here, the authors show that fMRI corresponds well to electrophysiological measures of spinal cord activity.
