White matter functional activity is a neglected area of research and key component for understanding the brain’s ability to adapt and learn. Participants completed a fine motor task during functional scans. DTI images were also collected for structural comparison. Functional correlation tensors were computed to examine local functional signal synchronicity. Strong agreement was found between the functional anisotropy maps and the structural anisotropy maps. Functional correlation tensors substantiate white matter functional response and identify a novel link between structure and function.
