Hi i used freesurfer labels in a study and i want to identify the broadmann areas corresponding to some labels, is there any correspondence between the two ?
Thanks
Hi Laouchedi
that is a big research question! The answer is a qualified yes, but it depends strongly on what labels you mean. In general we find that the closer you are to primary areas like V1/M1, the stronger the correspondence is. We do supply some explicit estimates of Brodmann areas, have you looked at them?

hi bruce,
related to this question, how are the stats/volumes of the BAs computed?

Hi Satra,
what version are you using? I think Anastasia implemented a thresholded version in 5.3, but perhaps she can comment. Bruce On Fri, 26 Jul 2013, Satrajit Ghosh wrote:

hi bruce,
currently 5.3, but the data i was looking at was processed with 5.1 and in that right ba44/45 was always larger.

if it's not the thresholded version that might reflect the fact that it is less well-predicted and so the borders are more spread out Bruce On Fri, 26 Jul 2013, Satrajit Ghosh wrote:

There is a *.thresh.label version of all the BA labels in 5.3, but I don't think it's used by default. You can try using those labels instead.

thanks guys. any thoughts on when the ba*.stats files will use these? right now i agree with bruce that they are biased by the predictability of the region. less accurate prediction -> greater volume.

You can search recon-all.log for the command that generates those stats and appply it to the ?h.BA.thresh.annot instead of ?h.BA.annot.

Hi thank you for the reply. Yes, i have looked at them, in fact i used the freesurfer parcels as nodes in a TBI connectivity study and i want to report my results both in terms of the freesurfer components and broadmann areas. i just asked, if since, some probabilistic map of broadmann areas exist ?
Thanks

those are the probabilistic estimates of the Brodmann areas (that is, the files in the label dir named h.BA*.label)
