Hi,
Brenna Argall and Peggy C. Christidis have created surface models of an averaged anatomical data set. The data used was the average of 27 anatomical data sets created by the MNI and UCLA groups (see Holmes, C.J. et al. J. Comp. Asst. Tomograph, 22(2):324-333). Talairach transformation was done using AFNI.
You can use these surfaces to display functional data in Talairach space without having to create surface models for individual subjects. If this sounds too good to be true, it might very well be. You may miss quite a bit of activation because of anatomical differences between brains. I think these surfaces are mostly useful for display purposes. So use with care!
The archive containing these surfaces is available on SUMA's web page:
