Exploring Connectivity of the Brain's White Matter with Dynamic Queries
2005
IEEE Transactions on Visualization and Computer Graphics
Preserved Fulltext
Abstract-Diffusion Tensor Imaging (DTI) is a magnetic resonance imaging method that can be used to measure local information about the structure of white matter within the human brain. ...
Combining DTI data with the computational methods of MR tractography, neuroscientists can estimate the locations and sizes of nerve bundles (white matter pathways) that course through the human brain. ...

We present a visualization technique for brain fiber tracts from DTI data that provides insight into the structure of white matter through visual abstraction. ...
We achieve this abstraction by analyzing the local similarity of tract segment directions at different scales using a stepwise increase of the search range. ...

In the current review, we explore the use of in vivo diffusion imaging and white matter tractography as a non-invasive method for the structural and functional parcellation of the human cerebral cortex ...
Cortical parcellation via white matter connectivity is based on the premise that, as connectional anatomy determines functional organization, it should be possible to segregate functionally-distinct cortical ...
Indeed, cellular lamination patterns and white matter connectivity profiles are but two of the brain's architectural elements which may be used to demarcate regions of specialization. ...

Methods for quantifying white matter asymmetry using diffusion MRI tractography have thus far been based on comparing numbers of fibers or volumes of a single fiber tract across hemispheres. ...
We propose a generalization of such methods, where the "number of fibers" laterality measurement is extended to the entire brain using a soft fiber comparison metric. ...
However, results have been inconsistent across studies, and much of the brain's white matter has not been systematically explored. ...
