"A new person entering the field of neurofeedback has a complex choice when selecting a system. There are no standards of practice in neurofeedback. Instead there are many camps that have evolved very diverse approaches which all achieve strong results. Here is a sampling of most of the successful ways to determine where on the scalp to place the sensors and what EEG features to train.
• Always use the same 2 sensor placements and default protocol designed to reduced EEG variability throughout the frequency range in every session, no matter who walks in the door.
• A 19-site quantitative EEG brain map and an extensive neuropyschological battery plus clinical judgement specify the pair of sites and frequency protocol emphasizing connectivity between sites is used for 20 sessions and are typically unchanged by client reaction.
• Clinical symptoms and responses determine placement and protocols. A client presenting with an addictive disorder is presumed to have too much beta in back of the head and these fast brainwaves are trained down.
• A clinical decision tree provides a starting point, but sensors and frequencies are changed many times during a session depending on client response with the goal of maintaining a feeling of the sweet spot.
• After obtaining a brain map, the most abberent site is treated first in some systems and last in another.
• 248 EEG readings are constantly compared with and trained toward database norms from a healthy population.
• A couple share several sensors and aim toward mutual alpha synchrony for interpersonal harmony.
• A single standard sensor placement is used to guide clients into brain states between dreaminess and passive awareness.
This last protocol is called alpha-theta training and has an impressive record with addictions of all kinds (Trocki 2006). "
