Alpha waves are electromagnetic oscillations in the frequency range of 8-12 Hz arising from synchronous and coherent (in phase / constructive) electrical activity of large groups of neurons in the human brain.
EEG Biofeedback Training (often called neurotherapy or neurofeedback) is a learning strategy that enables persons to alter their brain waves by getting a feedback of their present state.
