This document discusses brain waves and neurofeedback. It describes the different types of brain waves (delta, theta, alpha, beta, gamma) and what states each is associated with. It then discusses classic EEG which is used to diagnose neurological issues like seizures. Next, it covers neurofeedback (EEG biofeedback) which is used for diagnostics and therapy by teaching patients to regulate their brain waves. It also discusses 3D neurofeedback using LORETA which provides more advanced brain imaging and targeting of networks during neurofeedback training. Midbrain activation and the Shichida method of right brain training is briefly covered.
