Asymmetry Left/right asymmetry. A measure of the left/right asymmetry. It is presently based on a binomial test.
BA Brodmann area. Cytoarchitectonic parcellation of the cerebral cortex. These are group under WOROI: 43 - Brodmann area.
Bib A 'bib' item corresponds to a bibliographic item, - in most cases a scientific article. In the Brede Database each of these items are identified by the 'WOBIB' identifier. In most cases the 'bib' item has a corresponding entry in the Entrez-PubMed database.
BrainMap BrainMap is a database from Peter T. Fox and Jack Lancaster from the Research Imaging Center, Texas. A few of the items in the Brede Database corresponds to items in the original BrainMap database. There is a new BrainMap database, but the items of the Brede Database is not link to that.
DOI Digital Object Identifier. The DOI is used by publishers to identify, e.g., a specific scientific paper. As an example 'DOI: 10.1038/33402' refers to a paper by Epstein and Kanwisher. In the Brede Database the web-link associated with DOI is resolved through http://dx.doi.org which will usually forward the web-browser to the full text.
FMRIDCID fMRI Data Center identifier. Some of the items in the Brede Database correspond to items in the fMRI Data Center, of Jack Van Horn and Michael S. Gazzaniga, Dartmouth College. See, e.g., WOBIB: 28. There is an fMRI Data center indentifier index.
Hammers 'Hammers' refers to the digital human brain parcellation of Alexander Hammers et al., where 43 areas are defined. The numbers refer to the integer values in the volume ANALYZE file (template_43_final) provided by Alexander Hammers.
ICA Independent component analysis. ICA of the voxelized 'exp' and 'bib' structures.
MeSH UID Medical Subject Heading is a controlled vocabulary thesaurus from the National Library of Medicine. Each item has a unique identifier and some of them corresponds to an 'ext' item in the Brede Database (identified with WOEXT).
NMF Non-negative matrix factorization. NMF of the voxelized 'exp' and 'bib' structures.
PMID PubMed identifier. The identifier used in the PubMed service of the American National Library of Medicine to identify a scientific article. The web-link associated with PMID in the Brede Database will lead to the Entrez PubMed web-page with the abstract of the paper
PNG PNG is an image file format.
Svarer "Svarer" is a digital human brain parcellation by Claus Svarer and colleagues, see the Roi Svarer index for overview of defined regions and reference.
SVD Singular value decomposition. SVD of the voxelized 'exp' and 'bib' structures.
Talairach Talairach is the coordinate system and space for the human brain defined in the book by Jean Talairach and Pierre Tournoux: Co-planar Stereotaxic Atlas of the Human Brain from 1988. It defines the origo at the anterior commisure and x is the left/right axis with left being negative, y is the posterior/anterior with posterior being negative, and z is inferior/superior with inferior as negative. The so-called MNI-space is slightly different from the original Talairach space, - it is a bit larger. The coordinates in the Brede Database is usually reported with reference to the original Talairach space.
Tzourio-Mazoyer "Tzourio-Mazoyer" is a digital human brain parcellation also referred to as AAL. See Roi Tzourio-Mazoyer index for overview of defined regions and reference.
VRML Virtual Reality Modeling Language. A file format for interactive 3-dimensional models. These can be viewed with with VRML-browsers such as Octaga Player (OpenVRML/lookat, freewrl, Cosmo Player or Cortona). VRML2, also called VRML97, is the second version of this file format.
WOBIB Brede Database identifier for a 'bib' structure, i.e., a paper (scientific article). This contains one of more 'exp' structures. A WOBIB index is available
WOEXP Brede Database identifier for a 'exp' structure, i.e., an experiment in a scientific paper. This can, e.g, correspond to a 'contrast'. An 'exp' structure might have one or more 'loc' structures. A WOEXP index is available
WOEXT Brede Database identifier for a 'ext' structure: An 'external component', e.g., a cognitive component. Each 'exp' structure in the Brede Database will usually have one or more WOEXT associated with it.
WOPER Brede Database identifier for a 'per' structure: a person, usually an author of a scientific paper.
WOROI Brede Database identifier for a 'roi' structure: a region of interest, i.e., a brain area referred to by lobar anatomy, or a functional or Brodmann area.
