Depending on which regions are of interest, you might want to take a look at this preliminary version of the sub-cortical atlas from the Keuken group. I have made an AFNI compatible version you can download at the link below to try. Regions like the STN (sub-thalamic nuclei) are included.

Keuken atlas in suma

[afni.nimh.nih.gov]

Get that file and expand it with "tar xzvf ..." Then set the environment variable so AFNI's whereami knows it exist and uses it.

@AfniEnv -set AFNI_SUPP_ATLAS_DIR $outatlasdir

I've put surfaces there along with the "original" maximum probability maps and modally smoothed versions for each age group. These are my own modifications of the Keuken atlas, and I have yet to speak with the authors about this. That atlas and other related sub-cortical atlases are available in their original form here:

In the past, I've discussed a variety of methods for the transformation between Talairach space and MNI space. There are lots of options, and none of them are really "right" especially regarding the Talairach daemon atlas. There is no corresponding MRI template for the Talairach daemon, so these are all very rough approximations. Adding on to these difficulties of transformations and templates, the Talairach atlas is roughly sliced by coronal slices, and the atlas has a number of errors of inconsistencies across slices in 3D.
