The mesh data were saved in matlab/octave .mat format. Please load the .mat file in matlab/octave and export to your FEM simulator.
node: node coordinates (in mm) face: surface triangles, the last column is the surface ID, 1-scalp, 2-CSF, 3-gray matter, 4-white matter elem: tetrahedral elements, the last column is the region ID, 1-scalp and skull layer, 2-CSF, 3-gray matter, 4-white matter
The mesh contains 69865 nodes, 425224 tetrahedral elements and 120864 triangular surface elements (8108 for scalp surface, 14760 for CSF surface, 15320 for pial surface and 82676 for white-matter surface).
The optical properties of the brain atlas was described in Fang2010 Table 2 (the same properties were first used in Fang2009b). The properties for scalp/skull and cerebro-spinal fluid (CSF) are based on Custo2006 and those for gray and white matters are based on Yaroslavsky2002 at 630 nm.

The mesh data is in the public domain.
