Talairach coordinates
Talairach coordinates, also known as Talairach space, is a 3-dimensional coordinate system (known as an 'atlas') of the human brain, which is used to map the location of brain structures independent from individual differences in the size and overall shape of the brain. It is still common to use Talairach coordinates in functional brain imaging studies and to target transcranial stimulation of brain regions. However, alternative methods such as the MNI Coordinate System originated at the Montreal Neurological Institute and Hospital have largely replaced Talairach for stereotaxy and other procedures.
==History==
The coordinate system was first created by neurosurgeons Jean Talairach and Gabor Szikla in their work the ''Talairach Atlas'' in 1967, creating a standardized grid for neurosurgery. The grid was based on the idea that distances to lesions in the brain are proportional to overall brain size (i.e., the distance between two structures is larger in a larger brain). In 1988 a second edition of the Talairach Atlas came out that was coauthored by Tournoux, and it is sometimes known as the Talairach-Tournoux system. This atlas was based on single post-mortem dissection of a human brain.
The ''Talairach Atlas'' uses Brodmann areas as the labels for brain regions.
