These upstream credits apply to this derivative in addition to the NIH entry.

Changes by Synara (2026): orientation normalization, vertex clustering (2.5 source-coordinate units), removal of degenerate/duplicate triangles,
approximate spatial surface partitions, independent mesh names and display colors.
11 meshes represent bilateral frontal, parietal, temporal, occipital and cerebellar
surface regions plus a midline brainstem region. Boundaries are illustrative;
this is not an atlas registration, validated segmentation or patient reconstruction.
Exposed surfaces are open surface partitions, not reconstructed internal anatomy.
Only the three major connected surfaces are used; minor midline fragments and
small disconnected source artefacts are omitted.
No amygdala, hippocampus or deep-nucleus mesh has been invented.
