<h2><span style="color: rgb(82, 96, 105); font-size: 1rem; font-family: &quot;Open Sans&quot;, sans-serif;">Quantitative EEG
analysis (qEEG) refers to signal processing and extraction of features from the
EEG signal, in some cases there is a normative group that the individual being
surveyed is compared to, and sometimes the data is digitized without a comparative
reference.</span><br></h2>

<p>In the typical neurotherapy practice, 19 channel EEG is digitized, edited or adjusted to remove extra cerebral artifact, and subjected to spectral analysis using the fast Fourier transform (FFT).&nbsp;</p>

<p>There are numerous clinical normative databases for many different medical comparisons; normative databases help to evaluate clinical disorders. &nbsp;The National Library of Medicine’s database has a comprehensive list of normative databases, that can
    be found by search for “normative database: at: <a href="http://www.ncbi.nlm.nih.gov/sites/entrez">http://www.ncbi.nlm.nih.gov/sites/entrez</a>. In using a normative database, we are comparing a single person to a population of “normal” individuals
    for comparative purposes. A normative database will not only identify frequencies or metrics in which the patient is not normal, but will also identify the degree of their deviance. </p><br>
