"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). "
