SVReg Atlas Description

Description of BCI-DNI_atlas

BCI-DNI_brain_atlas_mainThe BCI-DNI_brain atlas was prepared using a high-resolution (0.5 mm × 0.5 mm × 0.8 mm) 3D MPRAGE scan of a right-handed adult woman in her mid-thirties, acquired at USC’s Dornsife Cognitive Neuroscience Imaging Center on a 3T Siemens MAGNETOM Tim Trio scanner. It is a brachicephalic brain.

The MPRAGE image was processed in a semi-automatic fashion using BrainSuite with meticulous manual corrections of the skull-stripping, cerebrum, and white-matter masks using the BrainSuite GUI interface and included a semi-automated bias field correction using the BFC Correction tool (http://neuroimage.usc.edu/neuro/Resources/bfc_correction_tool). All volumetric labels and sulci were drawn manually by Hanna Damasio, author of the human brain atlas, “Human Brain Anatomy in Computerized Images” (Oxford University Press, 2005) and Director of the Dornsife Cognitive Neuroscience Imaging Center (DNI) at the University of Southern California. The Sulcal Tracing Protocol [1] can be found here http://neuroimage.usc.edu/CurveProtocol.html.

The transfer of the volume labels to the surface mesh was done automatically using SVReg processes and hand-perfected using a Sulci-Surface Correction tool.

All extractions and manual corrections were performed by Soyoung Choi and approved by Hanna Damasio.

Sulci:
26 sulci on each hemisphere are marked according to the BrainSuite curve protocol [1]. Details can be found at http://neuroimage.usc.edu/CurveProtocol.html
Additional sulci are marked on a second set of curves totaling 39 sulci on the left hemisphere and 37 sulci on the right hemisphere.
