MRI Data

The data set includes 595 brains from 12 primate species. Preprocessed surface files were  smoothed and normalized using our computational pipeline. For each specimen, there are 22 files containing, for each hemisphere: coordinates and connectivity for the smoothed and normalized pial (?h.pial.asc) and white (?h.white.asc); mesh file for the alpha surface (?h.alpha.ply); thickness at each vertex (?h.thickness.asc); sulcal depth (the distance between pial surface and alpha surface) at each vertex (?h.sulc.asc); curvature (k1, k2, SI, K, H) at each vertex of the pial surface (?h.pial.k1.asc, ?h.pial.k2.asc, ?h.pial.SI.asc, ?h.pial.K.asc, ?h.pial.H.asc); area of the pial surface, defined at each vertex  (?h.pial.area.asc)

A T1-weighted chimpanzee template (JunaChimp) based on 220 structural images as well as segmentation and registration templates (TPM & Shooting template) for tissue segmentation and non-linear registration. A macroanatomical parcellation (Davi130) of the chimpanzee cortex, basal ganglia and cerebellum within the chimpanzee template space.

Atlas of white matter tracts in chimpanzee brain. Tractography recipes in standard space for the major white matter bundles of the chimpanzee brain and, for comparison, the human and macaque brain.

A comprehensive atlas of white matter tracts in the chimpanzee. Bryant KL, Li L, Eichert N, Mars RB. PLoS Biol. 2020 Dec 31;18(12):e3000971. doi: 10.1371/journal.pbio.3000971. 

Chimpanzee-human cortical expansion map. In vivo MRI data from 29 adult chimpanzees and 50 adult human subjects were analyzed. Vertex-wise and region-wise expansion was calculated in reference to the 114-region subdivision of the Desikan-Killiany atlas (DK-114). 

Genetic mapping and evolutionary analysis of human-expanded cognitive networks. Wei Y, de Lange SC, Scholtens LH, Watanabe K, Ardesch DJ, Jansen PR, Savage JE, Li L, PreussTM, Rilling JK, Posthuma D, van den Heuvel MP. Nat Commun. 2019 Oct 24;10(1):4839. doi: 10.1038/s41467-019-12764-8.

Diffusion MRI was used to reconstruct the connections of the cortical hemispheres of the chimpanzee and an exploratory analysis was performed of the grey matter structures of the chimpanzee cerebral cortex and their underlying white matter connectivity profiles. Results images are compatible with Connectome Workbench.

Concurrent analysis of white matter bundles and grey matter networks in the chimpanzee. Mars RB, O'Muircheartaigh J, Folloni D, Li L, Glasser MF, Jbabdi S, Bryant KL. Brain Struct Funct. 2019 Apr;224(3):1021-1033. doi: 10.1007/s00429-018-1817-8.

Connectivity matrix from chimpanzee DTI. Voxel-wise diffusion reconstructed using GQI, fibers reconstructed using deterministic fiber tracking (8 seeds per white matter voxel). Matrix describes group matrix based on 60% prevalence threshold.

Evolutionary expansion of connectivity between multimodal association areas in the human brain compared with chimpanzees. Ardesch DJ, Scholtens LH, Li L, Preuss TM, Rilling JK, van den Heuvel MP. Proc Natl Acad Sci U S A. 2019 Mar 18. pii: 201818512. doi: 10.1073/pnas.1818512116

MRI-derived cortical surfaces of many individual humans, chimpanzees, and macaques. The dataset presents two parcellation-based PFC delineations based on cytoarchitecture and function and show that a previously used morphological surrogate (cortex anterior to the genu of the corpus callosum) substantially underestimates PFC extent, especially in humans.
