Issues in automatic fiber tracking of arcuate fasciculus

[Yufan Wang]

Hi Frank,

I recently used atk to reconstruct arcuate fasciculus in HCP subjects and extracted tract-to-region connectome. However, I noticed that for several subjects (e.g., 178849, 463040), there were no detected intersections between the arcuate fasciculus and Brodmann areas 44 and 45. I have also observed similar cases in other datasets.

Given that the arcuate fasciculus is well known to connect to these regions, I was just wondering how this result should be interpreted.

Best,

Yufan
