Deep Chauvel's chimpanzee white matter atlas. The deep white matter atlas of the chimpanzee brain was built upon a cohort of 39 in vivo chimpanzees magnetic resonance imaging (MRI) scans shared by the Pr. William D. Hopkins, registered on a template space (Juna.chimp template from Vickery et al. 2020). The construction of this atlas is based on the analysis of the anatomical and diffusion MRI dataset using the tractography and fiber clustering tools available from the Ginkgo toolbox (CEA, NeuroSpin, BAOBAB, GAIA, Ginkgo Team, https://framagit.org/cpoupon/gkg). The atlas can be visualized using the BrainVISA/Anatomist viewer available at https://brainvisa.info/web/download.html. This atlas is composed of 42 white matter bundles including : - symmetrically on both hemispheres, the anterior, superior and posterior thalamic radiations, the arcuate, dorsal and ventral cingulum, the cortico-spinal tract, the fornix, the frontal aslants, the inferior fronto-occipital fascicle, the inferior longitudinal fasciculus, the middle longitudinal fascicle, the optic radiations, the uncinate fascicle and the visual occipito-temporal fibers, - interhemispheric bundles such as the anterior commissure and the Witelson's subdivisions of the corpus callosum (I, II, III, IV, V, VI, VII), - cerebellar bundles, such as the hypothamic-subthalamic fibers, the cortico-ponto-cerebellar fibers, and the parallel fibers, The atlas is provided using the Anatomist *.bundles/*.bundlesdata format for which metainformation can be found in the *.bundles file among which: - the labels of the different white matter bundles ('labels' entry), - the number of streamlines populating each white matter bundle ('curve3d_counts' entry), in the same order as the 'labels' key, - the total number of white matter bundles ('item_count' entry), - the total number of streamlines ('curves_count' entry)
