Database normalization is the process of organizing data into tables in such a way that the results of using the database are always unambiguous and as intended. Such normalization is intrinsic to relational database theory. It may have the effect of duplicating data within the database and often results in the creation of additional tables.

Method For Transforming Head Surface Coordinates To Brain Surface Coordinates And Transcranial Brain Function Measuring Method Using The Transformation Data

Data collected by a transcranial brain function measuring / stimulating method is accurately projected and displayed onto a brain surface. If there is no three-dimensional head image, data is projected and displayed onto the brain surface of a standard brain. The head surface coordinates are transformed to the brain surface coordinates of the brain surface underlying the head surface by, e.g., a minimum distance search method. The coordinates of a projected point on the brain surface of the head surface and the probability distribution are determined for a standard brain normalized with data on subjects.
