The files below are provided in the ascii versions of three different formats: FreeSurfer surface (*.srf), Chris Rorden’s highly efficient MZ3 format (*.mz3), Wavefront Object (*.obj) and Stanford Polygon (*.ply). The subcortical meshes were produced from the volumetric segmentations, as described here. The splitting of the cortical meshes into independent objects was performed using a custom script that soon will be released at (update: they are now available here). The generation of the cortical meshes and subcortical segmentations used FreeSurfer 5.2.0. The already realigned, averaged and bias-corrected volume, in nifti format, is available here. The images were registered and averaged to improve signal-to-noise ratio, as described here, and bias corrected using spm8 software. The images were acquired at the Research Imaging Institute, University of Texas Health Science Center at San Antonio, in a Siemens magnetom Trio 3T system, in two sessions, each consisting of 6 acquisitions of T1-weighted images, using a mprage sequence, with voxel size of 0.8×0.8×0.8 milimeters. These meshes can be used in a variety of compositions, for both scientific or artistic purposes. In this page you will find a set of 3D meshes of a true human brain, which were constructed from 12 volumes acquired using magnetic resonance imaging ( mri).
