Dear Tristan,

Do not be too obsessed by Brodmann areas. It is often better to give just
the anatomical location (gyri, sulci etc) and the MNI coordinate, and avoid
all the assumptions and errors in guessing the BA. Also, do not always
trust other's well intentioned 'guesses' of Brodmann areas in tables, since
these are so often incorrect on closer inspection, especially in areas away
from the authors' special interest. In any case, the activation/clusters
rarely correspond to the anatomical boundaries of 'standard' BAs .
If there are special reasons for a BA to matter, for your hypothesis or
inferences, then for the key areas you can suggest the BA and back it up by
the various methods proposed in recent mails. I see little advantage in
doing this for all peaks in an SPM. If your region of special interest is
covered by the dozen or so regions of the SPM anatomy toolbox, then I
personally suggest you use this as first line.
best wishes,
James
