We believe that this tool is an improvement for the macroscopical labeling of activated area compared to labeling assessed using the Talairach atlas brain in which deformations are well known. 7, 254-266) is provided as a freeware to researchers of the neuroimaging community.

Using this parcellation method, three procedures to perform the automated anatomical labeling of functional studies are proposed: (1) labeling of an extremum defined by a set of coordinates, (2) percentage of voxels belonging to each of the AVOI intersected by a sphere centered by a set of coordinates, and (3) percentage of voxels belonging to each of the AVOI intersected by an activated cluster. The 90 AVOI were reconstructed and assigned a label. Regions of interest were then drawn manually with the same software every 2 mm on the axial slices of the high-resolution MNI single subject. This procedure was performed using a dedicated software which allowed a 3D following of the sulci course on the edited brain. The MNI single-subject main sulci were first delineated and further used as landmarks for the 3D definition of 45 anatomical volumes of interest (AVOI) in each hemisphere.
