Resting-State Functional Connectivity MRI (fcMRI) is finding application in studying a variety of brain disorders. The underlying physiological basis of the BOLD resting-state fluctuations is still unknown. In this study, manipulation of the peripheral nervous system is performed to modify signal input into the thalamocortical system and disrupt interhemispheric correlation of the sensorimotor system. This study demonstrates the bilateral nature of resting-state correlation and may provide insight into the phenomenon.
