Background ========== Resting state fMRI data from 1000 subjects were registered using nonlinear deformation of the cerebellum in combination with surface-based alignment of the cerebral cortex. We mapped the complete topography of the cerebellum by estimating the principal cerebral target for each point in the cerebellum. The majority of the human cerebellum maps to association areas. Furthermore, the extent of the cerebellum dedicated to each cerebral network is proportional to the network's extent. Like somatomotor representations, cerebellar regions linked to association cortex have separate anterior and posterior representations that are oriented as mirror images of one another. The orderly topography of the representations suggests that the cerebellum possesses at least two large, homotopic maps of the full cerebrum and possibly a smaller third representation.

The first column of the text file specifies the value of voxels in the nifty values corresponding to the particular network. The second column of the text file specifies the names of the networks. For example, from the text file, voxels whose values = 3 corresponds to the network 7Networks_3.Columns 3 to 5 corresponds to the R, G, B values (ranges from 0 to 255) of the networks. Last column is all zeros (FreeSurfer's default). 7) Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz is a volume where each cerebellar voxel was assigned to the cerebral network (out of 17 cerebral networks estimated in Yeo et al., 2011) with the most similar pattern of connectivity.
