Brainwave Frequencies and Brain States
As you may know the human brain operates using electrical signals. These signals are called brainwaves or brain waves. Their transmission rate is measured in Hertz (Cycles per second). The dominant brainwave frequency determines the homonym brain state.
Why dominant? The brain does not operate whole itself in just a unique frequency. This means that some areas of the brain may produce more beta brain waves while some other areas may produce brainwaves of different frequency.
The dominant frequency is the one which determines the mind state. So, when we say that we enter the alpha state, this doesn’t mean that our brain generates only alpha waves, , but that alpha waves are more among all the others who have different frequency.
So we have the following brainwave classifications according to their frequency:
o 0.5-4 Hz Delta Brain Waves, deep dreamless sleep
o 4-7 Hz Theta Brain Waves, REM, super learning mode
o 8-13 Hz Alpha Waves, relaxed, drowsiness
o 13-30 Hz Beta Waves, alertness, fast thinking, anxiety
o 30-100 Hz Gamma Waves, Associated with advanced meditation, consciousness elevation.
There are also two new classifications, the lambda and epsilon waves. These two are correlated as the epsilon waves who have very low frequency, below 0.5 Hz, may contain very high frequency lambda waves, 100 Hz – 200 Hz. This sounds confusing, but you can spot lambda waves if you zoom in an epsilon wave line.
