It introduced a coordinate system to identify and label different brain regions ( Fig. This atlas has become one of the standard reference systems in human brain mapping. Talairach and Tournoux then constructed the third human brain atlas (in printed form) in 1988 from the single postmortem brain of a 60 year old French woman. The first stereotactic atlas of grey nuclei was published by Talairach and coworkers in the year 1957, followed by a second atlas in 1967. Length and height are shorter than MNI-152 but width is more Height is shorter than IT and MNI-305 but width is same The article falls under the following headings: (i) a detailed review of available brain templates (ii) steps involved and the rationale in creating a new population-specific brain template using LONI pipeline (iii) brain atlas applications in various imaging modalities and (iv) clinical application.ĭoes not fully cover top of head & cerebellum This article provides a comprehensive review of the nine most commonly used brain templates from the Talairach and Tournoux atlas to the Chinese brain template, describes the rationale behind the atlas construction protocols, and provides examples of specific computational neuroscientific studies. The more advanced brain templates using multiple subjects have higher signal-to-noise ratio, provide better contrast between grey matter and white matter, and quantify typical variations within the study cohort or the population of interest. Digital brain templates, or atlases, generated either from a single-subject or from multiple subjects, have begun to replace the conventional printed brain template (e.g., Talairach and Tournoux atlas). We conclude by discussing the scope of brain templates as a research tool and their application in various neuroimaging modalities.Ī brain template is a specific anatomical presentation of the brain depicting finer anatomical details (e.g., nuclei, cortical areas). The manuscript also provides the automated workflow-based protocol for designing a population-specific brain atlas from structural MRI data using LONI Pipeline graphical workflow environment. A chronological outline of the development of brain template design, starting from the Talairach and Tournoux atlas to the Chinese brain template (to date), along with their respective detailed construction protocols provides the backdrop to this manuscript. This manuscript provides a comprehensive review of the history, construction and application of brain atlases. #Human brain mapping template registration#Further, there are certain differences (e.g., brain shape and size) in the brains of populations of different origin and during diseased conditions like in Alzheimer’s disease (AD), population and disease-specific brain templates may be considered crucial for accurate registration and subsequent analysis of fMRI as well as other neuroimaging data. Brain templates also find application in other neuroimaging modalities, such as diffusion tensor imaging and multi-voxel spectroscopy. Analysis of fMRI data requires the registration of the data to a reference brain template in order to identify the activated brain regions. On the other hand, functional MRI (fMRI) provides information on the brain activity during performance of a specific task. Structural magnetic resonance imaging (MRI) provides anatomical information about the brain in healthy as well as in diseased conditions.
