We compare whole brain functional connectivity to the Vim thalamic nucleus at 3T and 7T, and demonstrate that the higher spatial resolution and higher contrast-to-noise ratio at 7T results in maps that are more specific to the function of that thalamic region and the connectivity maps from the 3T data are likely lacking in specificity due to partial volume of signal from neighboring thalamic regions.
