the structures don't need a threshold. Do you know that pars triangularis
is left lateralized? For the BAs will get you a solution

Dear Bruce,
We don't used any thresholding by ourselves, we just took BA44 volumes out
of the text-file in the stats directory.
Should we use thresholded values instead of the volumes reported by the
text files in the stats directory?
Could we use the volumes reported by the aparc.stats and aseg.s
Dear FreeSurfer,
I am looking for a database of brain areas and their associated functions.
Is it the content of the FreeSurfer software? For example, if I point to a
certain brain area (e.g. Broca's area), will FreeSurfer tell me its
associated function (e.g. speech production)?
Thank you

Hi Gabor
are you thresholding the BA4 label? In 5.2 we will distribute some tools
to automatically threshold the labels so that the predicted area has the
average area of the input labels. The right BA44 had more spatial spread
than the left, so you might be including a lot of low probability
Dear Bruce,
In the paper "Left-right asymmetry in volume and number of neurons in adult
Broca's area." by Katrin Amunts, 10 subjects (5 men and 5 women) were
studied, and the volume of BA44 was greater in the left hemisphere than in
the right in all ten cases. So, it is very strange that the volum
