CIFT-Geometry IV: Three-Dimensional Cortical Field Simulation on fsaverage5 — P8 Confirmed on Cortical Surface

CIFT-Geometry IV extends the laminar biLayer model (Geometry III, DOI: 10.5281/zenodo.20783981) to a full 3D cortical surface simulation using the fsaverage5 atlas (10,242 vertices, 71,682 edges). The cortical field Φ(x) is modulated by an anatomical cortical architecture proxy compatible with myelination gradients [M_i(x) = thick(x)⁻¹ + sulc(x)]. P8 is confirmed on cortical surface: NT is the unique regime with simultaneously low C1∩C2_local. Results: C1: NT=0.217, ASD=0.387, ADHD-c=0.592, SOC=0.707. C2_local: NT=0.027, ASD=0.098, ADHD-c=0.768, SOC=0.782. Related to: 10.5281/zenodo.20783981.
