Winkler reconstructed a single human brain from twelve registered 0.8 mm
isotropic T1-weighted MRI acquisitions made on a Siemens 3T scanner at the
Research Imaging Institute, University of Texas Health Science Center at
San Antonio. The source uses FreeSurfer 5.2.0 for cortical surfaces and
subcortical segmentation.

This web adaptation combines the original left and right pial surfaces,
left and right cerebellar cortex, and brainstem in their shared anatomical
coordinates. The mesh was simplified to 223,484 triangles, uniformly scaled
and reoriented for display. Smooth vertex normals and geometric ambient
occlusion were added for lighting. The software renderer uses a 49,158-triangle
copy of the same geometry. Both versions use the same ivory display material.

Cortical, cerebellar and brainstem surface contours were checked against the
source MRI on left parasagittal and near-midline sections. The inferior extent
of the brainstem follows the original FreeSurfer label.
