Functional MRI is an essential tool for mapping brain function, and correlations between MRI signals in a resting state are interpreted as depicting functional connectivity between regions. Studies in non-human primates have proven useful to validate the basis of resting state fMRI, and to relate fMRI findings to neural electrical activities. Resting state correlations have also been discovered in the spinal cord, and these change after an injury and provide a biomarker of cord integrity. In white matter tracts, correlations between resting state MRI signals from adjacent voxels are anisotropic and reveal underlying structures, while synchrony between specific white matter tracts and parcellated cortical regions during a task and in a resting stated is also evident. These observations provide new insights into the functional architecture of the brain and suggest new directions for fMRI.
