What are Brainwaves?
The brain is made up of billions of cells called neurons,
that communicate with each other through electrical signals.
With millions of neurons sending signals simultaneously,
enormous amounts of electrical activity is produced in
the brain. Sensitive medical equipment, such as an EEG,
can detect this activity.
The culmination of electrical activity of the brain
is referred to as a BrainWave because of its cyclic, "wave-like" pattern.
Common brainwave types and their associated mental states
include:
Beta 12Hz - 38Hz Wide awake, the general mental state
of most people during the day
SMR (sensorimotor rhythm 12 - 15Hz) Stimulation in
the range can result in relaxed focus and improved attention.
Beta 1 (15 - 20 Hz) - Increased mental abilities, IQ
and focus
Beta 2 (20 - 38Hz) - Highly alert, even anxious
Alpha 8Hz - 12Hz Alert while deeply relaxed and not processing
information. The mental state of early morning or daydreaming
with enhanced visualization and receptiveness to suggestion.
Theta 3Hz - 8Hz Light sleep or extreme relaxation. A
hyper-suggestible state.
Theta 1 (3 - 5 Hz) If suppressed, can improve concentration,
ability to focus attention
Theta 2 (5 - 8 Hz) Very relaxed and dreamful sleep, good
for mental programming
Delta 0.2Hz - 3Hz Deep, dreamless sleep. Slowest of brainwaves
and the most dominant. Your body is healing itself and
you do not dream. It is theorized that Delta waves have
specific effects on the limbic system, the amygdala and
hypothalamus. Delta frequencies appear to "sooth" these
neural structures and can be very effective reducing
migraines, fibromyalgia, chronic pain and blood pressure. |
