EEG OVERVIEW

BETA (12 hz - 27 hz): 

• Wide awake. This is generally the mental state most people are in during the day and most of their waking lives. Usually, this state in itself is uneventful, but don't underestimate its importance. Many people lack sufficient beta activity, which can cause mental or emotional disorders such as depression, ADD, insomnia, and low SMR production (a sub-range of beta at 12-15hz) which may be related to insomnia. Stimulating beta activity can improve emotional stability, energy levels, attentiveness and concentration. 

ALPHA (8 hz - 12 hz): 

• Awake but relaxed and not processing much information.  When you get up in the morning and just before sleep, you are naturally in this state. When you close your eyes your brain automatically starts producing more alpha waves. Many studies monitoring the EEG activity of experienced meditators have revealed strong increases in alpha activity. Alpha activity has also been connected to the ability to recall memories, lessened discomfort and pain, and reductions in stress and anxiety. 

THETA (3 hz - 8 hz): 

• Light sleep or extreme relaxation. Theta is also a very receptive mental state that has proven useful for hypnotherapy, as well as self-hypnosis using recorded affirmations and suggestions. 

DELTA (0.2 hz - 3 hz): 

• Deep, dreamless sleep. Delta is the slowest band of brainwaves. When your dominant brainwave is delta, your body is healing itself and "resetting" its internal clocks. You do not dream in this state and are completely unconscious.  

An EEG is a non-invasive test used to measure and record the electrical activity of the brain. It is generally considered a safe procedure with minimal risks.

FOOD & MEDICATION

• Take your usual medications unless instructed otherwise.
• Don't drink caffeine (energy drinks, coffee, etc.) prior to EEG appointment.
• Only drink sugar (juice or Gatorade) 30 minutes prior to EEG appointment.

OTHER PRECAUTIONS:

Please wash your hair the night before. Hair must be completely dry before doing your EEG. All hair pieces including (toupees, weaves, hair extensions, etc.) should be removed during the EEG. Hair products can make it harder for the EEG headset to attach to your scalp.

• Conditioners
• Hair Creams
• Hair Sprays
• Styling Gels
• No Metal Clips
• Bobby Pins  
• Other Headwear
