Destrieux C, Fischl B, Dale A, Halgren E.An automated labeling system for subdividing the human cerebral cortex on MRI scans into gyral based regions of interest. Desikan RS, Ségonne F, Fischl B, Quinn BT, Dickerson BC, Blacker D, Buckner RL, Dale AM, Maguire RP, Hyman BT, Albert MS, Killiany RJ.The details of each of the atlases above are in the following publications:
To download all the models at once, choose the format you want here: srf mz3 obj ply. The meshes for the same brain, in different formats, can be downloaded here: srf mz3 obj ply. However, the segmented volumes that are part of the subcortical stream can be used to generate surfaces for visualisation purposes, as described here.
These are not produced directly by the FreeSurfer pipeline.
In addition to the above cortical meshes, surfaces for subcortical structures are also available. atlas, one region per file.Ĭortical mesh split according to the Desikan-Killiany-Tourville (DKT) atlas, one region per file. They should be coloured or textured using your own creativity, in your favourite modelling software.Ĭortical mesh split according to the Desikan-Killiany atlas, one region per file.Ĭortical mesh split according to the Destrieux et al. Note that the small figures below were generated using the FreeSurfer utility tksurfer, but the actual model files do not contain any colours. This includes 3D Studio max, daz Studio, Houdini, Autodesk Maya, FreeCAD, Rhino, MeshLab, and many others. Click here for more information on these formats for mz3, click here.Īlthough the title suggests that these files are meant to be used with Blender, they can in fact be used with any computer graphics application that can import these formats. 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).
