Striatal Parcellation Estimated by Intrinsic Functional Connectivity
Data from 1000 young healthy adults were registered using nonlinear deformation of the striatum in combination with surface-based alignment of the cerebral cortex. All data were acquired on Siemens 3T scanners using the same functional and structural sequences. A clustering approach was employed to identify and replicate networks of functionally coupled regions across the cerebral cortex (see Yeo et al. 2011). The complete topography of the striatum was then mapped by estimating the principal cerebral target for each voxel in the striatum (see Choi et al. 2012 for more details). The parcellations agree with prior models based on monkey anatomy that divide the striatum into broad functional territories of reward, cognition, and motor function. The majority of the human striatum maps to cerebral association areas, with distinct zones of the striatum coupling to the distributed regions that comprise each large-scale associationetwork.
The striatal volumes in which each striatal voxel is assigned to a cerebral network (using either the 7 or 17 network solution in Yeo et al. 2011) are available for download here.

1. FSL_MNI152_FreeSurferConformed_1mm.nii.gz is the FSL MNI152 1mm template interpolated and intensity normalized into a 256 x 256 x 256 1mm-isotropic volume (obtained by putting the FSL MNI152 1mm template through recon-all using FreeSurfer 4.5.0)
2. Choi2012_7Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz is a volume where each striatal voxel was assigned to the cerebral network (out of 7 cerebral networks estimated in Yeo et al., 2011) with the most similar pattern of connectivity.
3. Choi2012_7Networks_MNI152_FreeSurferConformed1mm_TightMask.nii.gz is a volume where each striatal voxel was assigned to the cerebral network (out of 7 cerebral networks estimated in Yeo et al., 2011) with the most similar pattern of connectivity. Here, the striatal mask is tighter than in (2). The slices of this volume are shown in Choi et al., 2012.

In particular the networks are numbered from 7Networks_1 to 7Networks_7. The first column of the text file specifies the value of voxels in the nifti values corresponding to the particular network. The second column of the text file specifies the name of the networks. For example, from the text file, voxels whose values = 3 corresponds to the network 7Networks_3. Columns 3 to 5 correspond to the R, G, B values (ranges from 0 to 55) of the networks. Last column is all zeros (FreeSurfer's default).
