The Talairach Atlas
| Wikipedia says: "By defining standard anatomical landmarks that could be identified on different subjects (the anterior and posterior commissures), it became easier to spatially warp an individual brain image obtained through Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and other imaging methods to this 'standard Talairach space'. One can then make inferences about tissue identity at a specific location by referring to the atlas." Everything2 says:" There are some problems with the Talairach atlas. First of all, the atlas is based on one brain, which happens to be the brain of a 60-year-old French woman. Only one hemisphere was mapped, assuming that the hemispheres were symmetrical (although as a rule they are not). The most notable difference between the Talairach brain and other brains is its size. The Talairach brain is considerably smaller than the average brain by up to 10 millimeters in each dimension. Because brain sections are typically taken every 2 millimeters, this leaves a total of 15 slices that would go unnaccounted for. Also, the Talairach atlas leaves out the majority of the brain stem and cerebellum." |
