QEEG (Quantitative EEG) is essentially a diagnostic tool, used only
by specially qualified professionals. EEG is recorded simultaneously
from a number of sites on the head under a variety of task and
stimulus conditions (typically eyes open, eyes closed, reading, doing
math, etc.), and the results are compared to a normative database
(derived from similar readings taken on a large number of other
individuals), and then a "brain map" is produced for each condition
so the clinician can identify specific cortical areas with abnormally
high or low levels of activation and develop a neurotherapy treatment
plan to normalize the pattern, and thereby help the underlying
problem.
