Hi,
I have a query about the ability of probtractx to assess tracts that run
laterally to and from the angular gyrus. A recent study Greicius et al.,
2009, in NeuroImage, noted the difficulty of assessing whether or not there
are direct connections between the angular gyrus and the posterior cingulate
cortex. It was assumed in this study that these laterally running fibers
would be impossible to trace through the larger anterior-to-posterior
oriented tracts of the superior longitudinal fasiculus and the
superior-to-inferior tracts of the corona radiata.
I would be interested to know if anyone knows how bedpostx and probtrackx
are likely to fair in delineating tracts in this region and whether or not
it would be able to cope with the complexity of crossing fibres here.
With thanks,
Lar
