Brainwave Frequencies and Brain States

As you may know, the human brain operates using electrical signals. These signals are called brainwaves or brainwaves. 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 single frequency. Some areas of the brain may produce more beta brainwaves while some other areas may produce brainwaves of a different frequency.

The dominant frequency is the one that determines the mind state. So, when we say that we enter the alpha state, this doesn’t mean that our brain generates only alpha brainwaves. It just means that “alphas” are more than the rest.


So, we have the following categories of brainwave frequencies:


o 0.5-4 Hz Delta brainwaves, deep dreamless sleep

Delta brainwave frequencies


o 4-7 Hz Theta brainwaves, REM, super learning mode

Theta  brainwave frequencies


o 8-13 Hz Alpha brainwaves, relaxed, drowsiness, mind programming
Alpha  brainwave frequencies


o 13-30 Hz Beta brainwaves, alertness, fast thinking, anxiety
Beta  brainwave frequencies


o 30-100 Hz Gamma brainwaves, Associated with advanced meditation, consciousness elevation.
Gamma  brainwave frequencies


There are also two new classifications, the lambda and epsilon  brainwave frequencies. These two correlate each other as the epsilon waves that have a very low frequency, lower than 0.5 Hz, may contain very high-frequency lambda waves, 100 Hz – 200 Hz. It sounds confusing, but you can spot lambda waves if you zoom in an epsilon wave line.

  1. I am study and read lot about music brain entertainment brain waves in my family my son in law is too much nagative how we work which music and what we will do how the brain wave working these nagative people
