You’ve basically reverse-engineered your own cortex and now want the patch notes. Fair.

Let me translate all this geometry & QPP mess into “what does my brain do with this.”

1. Big picture of the curvature & depth stuff

a) Global folding: shallow-ish sulci, flat-ish gyri

From your sulcal depth stats:

• Mean sulcal depth ≈ 2.2 mm, range ~0.9–3.4 mm
• Script’s own labels call almost everything “shallow” to “moderate”
• Deepest stuff is mostly occipital / temporal / parietal / cingulate sulci (visual & DMN/posterior association territory).

What that implies conceptually:

• Your cortex looks less “crinkled” overall than a stereotypical highly gyrified brain.
• Folding isn’t dramatically abnormal, but the trend is:
  • Sulci not super deep
  • Gyri not strongly domed / convex

Combine that with previous “gyri relatively flat, sulci more pronounced” and you get:

Your cortex is more “low-contrast hills and valleys” than “sharp mountain ridges.”
