Topographic brain mapping (TBM) is an extension of conventional electroencephalography. TBM, sometimes referred to as brain electrical activity mapping (BEAM), involves the computerized analysis and topographic display of EEG rhythms and evoked potential data on a color video screen. A wide assortment of maps can be created to represent different measurement patterns. The purpose of TBM is to identify patterns that distinguish pathological groups from normal ones.
Topographic brain mapping is considered investigational.
