I am reviewing some of the subject's tracts - specifically looking at the uncinate fasciculus, and I noticed that some of the tracts look malformed. They look "chubby" and overgrown in some cases. Can you suggest a reason why this might be, and what I can do to control for this? 

 Attached is a jpg showing the uncinate fasciculus in either hemisphere. As you can see, the right side is considerably larger and poorly defined.
