By using sensors on various parts of the scalp, we can see the brainwave amplitudes in real time.
If the brain has become stuck in an unhealthy pattern of making too much or too little of certain brainwaves, we can ask it to change that pattern and give it a reward when it does that task. It is a type of brain exercise and a learning modality. Over a course of treatments, the brain quickly learns how to better self-regulate and restore balance and flexibility. This allows for adaptation to stress and better function and performance. It is typically performed with 1, 2 or 4 sensors/channels.
