Footnotes:
  1. MNI: Montreal Neurological Institute coordinates, based on the average of 152 healthy brains
  2. T&T: Talairach & Tournoux coordinates, based on a single, elderly, alcoholic's brain
  3. Transformations are based on Matthew Brett's mni2tal equation: MNI=([1.14X+0.8],[1.03Y+3.32],[1.14Z+0.05Y+0.44])

Note that many articles do not state explicitly whether the data were reported using the T&T template or the MNI template. In these cases, if they used SPM96 or later versions or FSL, I assumed it was the MNI brain, if they used BrainVoyager, I assumed the T&T brain. Also, note that some people continue to say 'Talairach space' for the general approach to mapping brain coordinates, whereas the data they report are from the MNI template. Very confusing. Further, lots of article might rely on the unreliable Talairach Daemon or other automated brain-labelling programs, rather than on individual anatomy. Finally, people make mistakes. As such, the returned coordinates and labels are estimates only, and should not be relied upon in any way. Anatomical localisations based on Talairach & Tournoux (1988) coordinates are rubbish - based on the single brain of old alcoholic woman, they are not representative of the average, healthy brain. Anatomical localisations based on the MNI coordinates are better, since they are based on the average of 152 healthy brains. Probabilistic locatalisations are event better, as they reflect the uncertainty over any 'average' brain locations. If the above table shows coordinates in italics, then these are approximate and based on the MNI2TAL equations of Matthew Brett. If you don't believe the above, see the great article by Devlin & Poldrack (2007):
