| Types/Bands of Brainwaves
When scientists first measured brainwaves they found that they were connected
to different mind states, or states of consciousness. Since then they
have divided the brainwaves into four predominant speed ranges, or types.
The brain is constantly emitting nearly every type of brainwave. However,
based on the strength of certain bands of brainwaves a person can be
said to be "in" a certain brainwave or band.
||Mental State/Sub-Categories (bands)
||15Hz - 38Hz
||Individuals in this state are Fully Awake and Generally Alert.
||15 - 20 Hz
||Can increase mental abilities, IQ, and mental focus.
High Beta (20 - 38Hz) – Can increase alertness, but may also
||12Hz – 15Hz
||SMR (sensorimotor rhythm) is related to body motion. Increasing
this can result in increased focus, improved attentive abilities.
||8Hz - 12Hz
||>Most people experience this state just after waking and right
This band is ideal for Relaxation, Stress Relief, Self Hypnosis,
stimulation of the Immune System and Accelerated Learning.
||3Hz - 8Hz
||Most people enter into this state during light sleep or extreme
||3 - 5 Hz
||This band is ideal for Meditation and Sleep Replacement.
Additionally, research has shown that the suppression of this band
can improve concentration and attention, as well as reduce hyperactivity.
||5 - 8 Hz
||This band is ideal for Improved Sleeping Patterns, Treatment of
Insomnia and Creative Visualization.
||0.2Hz - 3Hz
||This state is experienced during deep, dreamless, non-REM sleep.
Delta is the slowest band of brainwaves. While in Delta the body
is healing itself and resetting internal clocks.
This band is ideal for Accelerated language retention and stimulating
the release of growth hormone.
