Quantitative EEG refers to the transformation of a particular EEG feature into a numerical value and compares it to a paired locus of recording. This technique incorporates more electrodes than traditional EEG to allow for more comprehensive representation of brain electrical activity.

Current Knowledge

With the use of spectral analysis and evoked potentials, certain clinical conditions may be identified, providing more sensitivity than traditional EEG. The output of quantitative EEG is a topographic, color-coded display of relative EEG activity. Quantitative EEG may have a role in measurement of pharmacologic effectiveness in psychiatric treatment as well as prognostication in coma and minimally conscious states. Quantitative EEG also forms the basis for the rehabilitation intervention of neurofeedback or EEG biofeedback. Individuals are theoretically taught to modify, through the use of computerized feedback, the electrical activity of their own brains. As in other...
