hi there
>Dear SPMers:
> I have a question about the MNI coordination and the Talairach coordination. Are spm using the Talairach or MNI space? In the SPM5 Mannual, "This module of normalization spatially (stereotactically) normalizes MRI, PET or SPECT images into a standard space defined by some ideal model or template image[s]. The template images supplied with SPM conform to the space defined by the ICBM, NIH P-20 project, and approximate that of the the space described in the atlas of Talairach and Tournoux (1988). The transformation can also be applied to any other image that has been coregistered with these scans." But the MRIcro userguide said that "There are two popular frames of reference for brain imaging: MNI space (used by SPM) and Talairach space (used in the atlases of Talairach and Torneaux)." Therefore, I am confused.

well as it is said SPM uses the MNI space (see on the web ICBM at
http://www.bic.mni.mcgill.ca/) -

simply the ICBM template is in the same orientation as the Talairach
(AC/PC) so you can compare both of them (see
http://imaging.mrc-cbu.cam.ac.uk/imaging/MniTalairach)

MNI

yes
>What about TSU utilities?

you should go for MSU
> If I also want to report the Brodmann areas information in my article, need I change the coordination to MNI or Talairach space?

those plug in do the job for you - but still you shoud have a look with
an atlas .. just in case
hope this helps
