MODIFIED EDUCATIONAL PRESENTATION DERIVATIVE. Invincible Human, 16 October 2026. Scalp geometry is MNE-Python bundled fsaverage-head.fif in MRI/surface RAS, with unchanged source shape and triangle topology, converted to normalized web JSON using the existing fsaverage5 brain presentation transform. MNE documents this as an approximate fsaverage head surface. EEG contacts and headband path are an illustrative proxy derived from an older standard montage after rigid fiducial alignment and projection to scalp. They are not exact Muse mechanical CAD, wearer measurements, a fitting guide, or a clinical forward model. Optical positions are schematic frontal anchors only. No MNE, FreeSurfer, MGH or Muse endorsement is represented.

Underlying fsaverage anatomy attribution and FreeSurfer licence retained alongside this derivative: All or portions of this licensed product (such portions are the "Software") have been obtained under license from The General Hospital Corporation "MGH" and are subject to the following terms and conditions: MODIFIED PRESENTATION DERIVATIVE, Invincible Human, 16 October 2026. This file converts the FreeSurfer fsaverage5 pial surface and matching Desikan-Killiany annotations to web JSON. One shared translation and uniform scale, decimal rounding, merged hemisphere indexing, calculated vertex normals, educational lobe grouping and normalized sulcal-depth shading values were added. Source cortical forms, hemisphere relationships and triangle topology were preserved. This derivative is not the original FreeSurfer distribution. For educational visualization only, not clinical use. The General Hospital Corporation, FreeSurfer contributors and funding agencies do not endorse Invincible Human. This optional extended derivative additionally includes genuine outer cerebellar and brainstem surfaces extracted from the matching fsaverage5 aseg volume. Modest voxel-space smoothing and marching-cubes isosurface extraction were applied and are documented in metadata. These structures retain their source registration with the cortical hemispheres.
