Topographic mapping of electric activity of the brain

: Quantitated neurophysiology and topographic brain mapping are reviewed. Certain information on the electrical activity of the brain may be more easily comprehended with the aid of topographic visualization of EEG and evoked potentials. Quantitated neurophysiology promises to make an important contribution to research in several fields of neuroscience, e.g. cognitive processing, psychiatry, dementia, epilepsy, cerebrovascular disorders, auditory and visual electrophysiology, and migraine. Provided that careful attention is paid to the elimination of artefacts, such methods may also be used as supplementary diagnostic tools in the clinic.
