Macaque Template Surfaces (FreeSurfer Format)

FreeSurfer-format cortical surfaces for common macaque MRI volume templates. These surfaces support visualization and analysis in standard neuroimaging workflows.

Templates

• NMT2 — NMT v2 0.5 mm symmetric (Sym) and asymmetric (Asym) template
• MEBRAINS — MEBRAINS template
• Yerkes19 — Yerkes19 macaque template (balsa)
• D99 — D99 template

Generation

Surfaces were derived from the white and pial surfaces provided with each volume template, along with NMT CHARM and SARM parcellations.

The full FreeSurfer-style pipeline (sphere, cortical ribbon, curvature, thickness, etc.) was completed using Brainana—a non-human primate MRI volume and surface preprocessing pipeline (preprint).

Volumetric atlas projection on surface

• CHARM: NMT CHARM
• Retinotopy: Retinotopy (polar angle and eccentricity) atlas from Arcaro MJ & Livingstone MS (2017). Detailed description see atlas-retinotopy_info.md.
