It is a non-invasive procedure, so there’s no blood, and no pain. A set of electrodes is placed on your head with a mousse-like gel placed at each site. During the training, you watch an educational DVD that flickers along with a bell ringing. The flickering and the bell automatically train your brain to regulate. A session lasts about 55 minutes. At the end of session, most people feel relaxed and calm. After a few sessions, many people say something like, “This noise is quieter,” or “My windshield is clean,” or “I am sleeping more soundly,” or “My thinking is clearer.”
