A Parcellation Scheme of Mouse Isocortex Based on Reversals in Connectivity Gradients

This dataset contains a parcellation of mouse isocortex into a hierarchy of subregions. The parcellation is based on the detection of gradient reversals in voxelized connectivity, as described in our latest preprint manuscript.

The connectivity dataset used for this purpose was the voxelized mouse connectome published by the Allen Institute for Brain Science, available at connectivity.brain-map.org (data) and github.com/AllenInstitute (code)

Region id annotations are provided in .nrrd format. Refer to the NRRD documentation for details.

The hierarchy is provided in the accompanying json file. For each region, an entry "structure_id_path" is provided that lists the ids of regions on the path from the root (i.e. isocortex) to the region in question.

For more information, please read the accompanying manuscript. We will provide the link here, once it is online.
