<p>When recording an EEG, 50% of the data arriving at the site of the electrode is from neurons directly underneath it, and 95% of the data comes from within 6 centimeters distance (that’s a circle with a diameter of 2 1/3 inches—big) (Nunez, 1982; 1995, Cooper et al., 1965). This is one of the reasons that EEG is limited in terms of what it can determine spatially (i.e. where something lives in the brain). LORETA neurofeedback training is Z-score training that uses three dimensional source localization so that the location within the interior of the brain can be pinpointed with accuracies of 1cm. LORETA neurofeedback is thought to target subcortical structures that are showing deviance in the amount of frequency generated.&nbsp;</p><p><b>LORETA Z-score&nbsp;</b></p><p>LORETA Z-Score neurofeedback is thought to regulate the deep structures of the brain and improve connectivity between the brain networks through targeting the central voxel within certain regions of the brain. In each session, a cap with 19 sensors is applied to your head. During training, your brainwaves learn to become balanced and normalized as they are rewarded.</p><p>The goal of LORETA is to reinforce stability of information processing in dysregulated networks and connections based on the client’s symptoms. It targets the specific areas of the brain and connections between nodes that are linked to the symptoms. In doing so it specifically targets deep brain structures that are out of balance. Similar to traditional Neurofeedback (single channel Neurofeedback) training it provides operant conditioning (rewards) based on your brainwaves compared to the brainwaves of a healthy population.</p><p>It is possible to train coherence, phase, and power from 88 Brodmann areas in LORETA Z-score neurofeedback.&nbsp;</p><p>There are a few ways to choose what regions of the brain to train using LORETA Z-score Neurofeedback. One means is using a symptom checklist, which is created from the patient’s EEG. Another method is using Neurodesigner.</p><p><br></p><p style="text-align: center;"><img src="@@PLUGINFILE@@/loreta-neurofeedback.png" alt="" width="762" height="1565" role="presentation" class="img-responsive atto_image_button_text-bottom"><br></p><p style="text-align: center;">Figure : Image from NeuroGuide Z-Score LORETA Neurofeedback<br></p><p><br></p><p><br></p>
