An example of arcuate fasciculus micro dissection and the QA-aided tractography.

<p>(A) The dissection of the arcuate fasciculus, pictured from the left hemisphere. (B) The tractography is generated by applying generalized deterministic fiber tracking to the grid sampling data with QA filtering. Although the images are from different subjects, remarkably consistent structures can be observed in both images, including the branching tracks to the prefrontal cortex and temporal gyrus.
