The IIT Human Brain Atlas project is in the 4th year of
development (www.nitrc.org/projects/iit2). The latest
version of the atlas contains high-quality artifact-free
anatomical, DTI, HARDI templates, and probabilistic gray
matter (GM) labels of the adult human brain in ICBM-152
space. The project is currently focusing on the
development of a probabilistic white matter atlas that
is complementary to the GM atlas, by performing
tractography in the state-of-the-art HARDI template
using the labels of the GM atlas as seeds. The present
work aimed to: a) evaluate the tractography results, and
b) generate probabilistic connectivity maps for pairs of
GM labels.
