Beta/SMR Brainwaves: As defined by the International Federation of Electrophysiology and Clinical Neurophysiology beta brainwaves have a frequency band of 12-15mHz. Beta/SMR (sensorimotor response waves) are localized by side and lobe of the brain. They are associated with relaxed, yet focused, behavior. It is believed that SMR brainwave frequencies make people feel more present and in the moment. Low SMR can cause a lack of focused attention, reflecting ADD. Increasing SMR through Neurofeedback can produce relaxed focus in an individual along with improved attentive abilities.

Alpha Brainwaves: As defined by the International Federation of Electrophysiology and Clinical Neurophysiology alpha brainwaves have a frequency band of 8-12mHz. Alpha waves are associated with relaxation and daydreaming. They are also present upon deep introspection. High frequency alpha waves don't normally occur when the eyes are open. The brain uses alpha wave frequencies to rest areas of the brain not processing or acting upon incoming sensory or motor information. If alpha brainwave activity becomes 'locked' and inhibited active participation of vital areas of the brain cannot occur in an efficient manner.

Theta Brainwaves: As defined by the International Federation of Electrophysiology and Clinical Neurophysiology theta brainwaves have a frequency band of 4-8mHz. They engage inner and intuitive subconscious. Theta waves are found in places in the brain where memories, sensations and emotions are held.

Delta Brainwaves: As defined by the International Federation of Electrophysiology and Clinical Neurophysiology delta brainwaves have a frequency band of .5-3mHz. Delta brainwaves are found during deep, dreamless sleep.
