Functional Localization of Patient Symptoms in the Brain
by Mary L. Tracy, MA PhD MFT

Electro-Imaging uses sophisticated computer analysis of Electroencephalographic (EEG, or brain-wave) recordings from the scalp to determine functional deficits in the brain. The technique is non-invasive and provides a wealth of information about the localization of brain dysfunction or dysregulation. The patient's EEG data is compared to that of age- and sex-matched "neurotypical" controls (individuals with no symptoms or history of head trauma). Areas of the brain that are dysregulated show up clearly on "brain-maps" and the degree of statistical deviation from normal can be determined both for the surface of the brain and deeper into core brain structures. Localization of these dysregulated areas is correlated with patient symptoms that are well-established in the research literature by virtue of classical neurological/behavioral studies, functional Magnetic Resonance Imaging (fMRI), Diffusion Tensor Imaging (DTI) and Single Photon Emission Computed Tomography (SPECT-scan) results.
