We provide resting-state functional MRI BOLD response timeseries as well as diffusion weighted MRI probabilistic streamline counts for twenty healthy subjects. Functional data is presented in the form of 1029 samples (timeseries) for 14 subcortical areas: bilateral Accumbens, Amygdala, Caudate, Hippocampus, Pallidum, Putamen and Thalamus (first 7 regions in the left hemisphere, followed by 7 regions in the right hemisphere). The data matrix is in the form #subjects x #timepoints x #areas. Structural data is presented in the form of a matrix in which each element (i,j) represents the number of probabilistic streamlines originating in region i and terminating in region j. The same regions are available as for the functional data, in the same ordering. Streamline counts from a region to itself have been discarded. More detail is provided in "Bayesian estimation of conditional independence graphs improves functional connectivity estimates", PLOSONE (forthcoming).
