Anatomical Labeling
Although there are a great number of anatomical coordinate spaces that are used to generate neuroanatomical labels in functional imaging studies, the two most widely used volume coordinate systems are:
- Talairach and Tournoux
- MNI/ICBM
Manual Labeling of Coordinates
The coordinates reported by spm8 are aligned with the spm8 tissue probability maps in MNI/ICBM space. To manually label the activity maxima reported by spm8 using the Talairach and Tournoux Co-planar Stereotaxic Atlas of the Human Brain (1988), it is first necessary to convert the maxima into the version of the Talairach coordinate system used in that atlas. A MATLAB tool for that purpose can be found here.
Automated Labeling of Coordinates
Neuroanatomical labels can be derived from volume-based atlases using:
- Talairach Daemon
- SPM Anatomy Toolbox and its manual
- xjview with the MNI Space Utility and the WFU_PickAtlas databases
Neuroanatomical labels can be derived from surface-based atlases using:
