Talairach & Tournoux Brain Atlas

It is a human neuroanatomical reference used to describe locations in the brain with standardized coordinates. The system became important in neuroimaging research because studies could report findings in a common spatial framework.

The atlas was created by Jean Talairach and Pierre Tournoux. The foundational edition was published in 1988.

It provides a stereotaxic coordinate framework for locating brain structures and imaging findings. Researchers can use those coordinates to compare the reported position of activity across studies.

No, Talairach coordinates and the later MNI space are different reference frameworks. Neuroimaging papers often name the space they use because a coordinate value can mean different anatomical locations in the two systems.
