Destrieux Atlas Changes

Author: C.Destrieux

See also CorticalParcellation.

The main changes between the aparc.a2005s atlas and the new (August 2009, Freesurfer v4.5) aparc.a2009s atlas include:

New parcellation of the cingulate sulci and gyri based on cytoarchitectonic and functional data: The cingulate gyrus, cingulate sulcus and intracingulate sulcus were grouped, and this group of anatomical structures was subdivided in several segments following the antero-posterior direction as proposed by Vogt (Vogt BA, Berger GR, Derbyshire SW. Structural and functional dichotomy of human midcingulate cortex. Eur J Neurosci 2003; 18: 3134-44. Vogt BA, Vogt L, Laureys S. Cytology and functionally correlated circuits of human posterior cingulate areas. Neuroimage 2006; 29: 452-66.):
- anterior (ACC) [G&S_cingul-Ant, 6],
- middle-anterior (aMCC) [G&S_cingul-Mid-Ant, 7],
- middle-posterior (pMCC) [G&S_cingul-Mid-Post, 8],
- posterior-dorsal (dPCC) [G_cingul-Post-dorsal, 9], and
- posterior-ventral (vPCC or isthmus) [G_cingul-Post-ventral, 10].
This author defined the Talairach coordinates of the limits between parts of the cingulate gyrus on cytoarchitectonics and functional arguments: we used the coronal planes of coordinates y=+30mm, y=+4.5mm, y=-22mm to respectively limit the anterior/middle-anterior, middle-anterior/middle-posterior, and middle-posterior/posterior-dorsal parts of the cingulate gyrus and sulcus. The posterior-dorsal and posterior-ventral parts of the cingulate gyrus were limited by the horizontal plane of coordinates z=+19.7mm.
Some parcellation names were shortened to fit in the tksurfer interface window (see table below).
Some small labels were grouped to increase the reproducibility of labeling (see table below).

This table lists the label differences between the C.Destrieux cortical atlases.
