Fp1, Fp2, F7, and F8 are near the orbital gyrus, which assists in error detection, often exaggerated in OCD.

The site-to-symptom match list is lengthy. Training with four channels makes sense when the presenting symptom is reflected by four or less locations. If the presenting symptom(s) is reflected by more than four locations then additional 4-channel training montages may need to be included during a training session. However, if possible, it may be more advantageous to train with six, eight or ten channels.

Location is critical to this method. The EEG neurofeedback practitioner checks all Z-score components including power, coherence, asymmetry, and power ratio when making the match between symptom and location. A brain map derived from clean EEG data is essential.

Neurofeedback practitioners focus on emotional, cognitive, and psychological issues—not medical issues, unless they are within the practitioner’s scope of practice and if there is research to support the training intervention.

Chapter 20 explores the use of symptom checklists when creating training protocols that employ surface Int’l 10–20 sites or ROI training (sLORETA); also see the introduction.

Train all locations: (1) 19-channel Z-score training or (2) sLORETA Z-score training of all ROIs. Training all 19 Int’l 10–20 locations with Z-scores would seem to cover all clinical issues. All electrodes are placed on the scalp. Sometimes Fp1 and Fp2 are omitted when there is undue eye blinking. Some clinics train all ROIs with or without 19 surface locations. Of course, sLORETA Z-score training needs all 19 electrodes connected to locate all ROIs.
