The collection of 3D photogrammetric models of ex-vivo dissections. Eight hemispheres - four left and four right - are available. For each hemisphere, a sequence of models represents the progression of tissue removal. The white matter fiber pathways dissected include the Posterior Transverse System, the Superior Longitudinal System, the Inferior Longitudinal System and the Basal Longitudinal System (Mandonnet et al., 2018)
Speciment 01
Right hemisphere. Decortication of the sulci. Dissection of the superficial and deep layers of the Posterior Transverse System (Vertical Occipital Fasciculus and Posterior Indirect component of the Arcuate Fasciculus), of the superficial and deep layers of the fronto-parietal Superior Longitudinal System (Superior Longitudinal Fasciculus), and of the fronto-temporal Superior Longitudinal System (Arcuate Fasciculus) with the engraving of its stem. Removal of the opercula with the exposure of the insula. Removal of the insula with the exposure of the main body of the Inferior Longitudinal System (Inferior Fronto-Occipital and Uncinate Fasciculi) and of its fronto-orbital projections.
The collection of cortical and subcortical annotations of the 3D photogrammetric models of ex-vivo dissections. Manual annotations highlighting the sulco-gyral anatomy and white matter connections of interest of each specimen are provided. Atlases of cortical parcellations derived from multiple modalities and rendered to the surface of each specimen are also made available.

The collection of in-vivo tractography bundles registered into the space of the 3D photogrammetric models of ex-vivo dissections. We provide the tractography reconstruction of white matter connections corresponding to the ones highlighted by the manual segmentations and an atlas.
