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.


Brain Evolution system


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

  2. I am a very frequent user of apps that produce specific sounds that vibrate at the same frequencies (called Hertz which is just a funny name for ‘Cycles Per Second’, which are, essentially, the same as ‘beats per minute’ musicians hear on a metronome, but we measure these ‘beats’ within a second, instead) just like musical notes which all have their own frequency vibration, or Hertz. Well, it turns out that OUR VERY OWN BRAINS operate at many different frequencies- measured on the Hertz scale-and we can, with the use of certain apps or programs, TRAIN our brain to play copycat. For example, if I was tense and wished to calm down, I would use one of the apps to listen to a lower level of Hertz in order to calm…my…mind. When we listen to a set Hertz frequency, our brain will, usually within 10-30 minutes, begin to COPY the lower Hertz level. And so I’m sure you can guess what would happen.
    Yes! If our brain is now copying the new, slower Hertz, then it will become more relaxed. And if the brain is relaxed, then the rest of us will become relaxed! How cool is that?! Finally, WE can tell our brain what to do, instead of the brain always telling us what to do! I would suggest looking for “Binaural Beats” apps. Aural means ears or sounds, and Bi, or in this case Bin, means 2(two). So, this is the ear version of bin-(two) -oculars (eyes or sight) and we already know that binoculars help you to see things better from far away. When you get the app, you will need headphones or earbuds, etc. but it WILL NOT WORK if you listen to it using speakers. The apps work by sending out a sound to each ear that are Almost the same… almost. The brain is so amazing that it can tell the difference between two sounds that, if you compared both out in the open, most people would have a hard time telling them apart. Some people could tell you that one is a little higher or lower pitch than the other. And it’s true…they are! See a sound like one of the really low piano notes…they begin at around 28 Hertz which we shorten to Hz…like a nickname. Well we can only hear things with a Hz of 16 or higher, all the way to around 18,000. Some people have been able to hear as low as 13 or 14, and as high as 22,000 (twenty-two THOUSAND!) The problem is that our brains have Hz frequencies all the way down to 0.5 and that is only if you practice a LOT! The usual lowest limit is about 1.0. Usually, that means you are in a very very deep sleep and anyone that tried to wake you would have to try really hard to get you awake! Good thing this level does not happen very often and never for very long. Our normal range when we are watching TV is between 5.5 and 8Hz. Well, what if you were too anxious and stressed out and your brain is all the way up around 50 or 55! A nice 6 or 7 would be wonderful right about now. But wait! If we don’t hear ANYTHING below 16 (14 if you have super hearing), then how can we possibly get near 8?! Even 10 is impossible!
    AHA! This is why you need headphones/ ear buds or any other type so that you can make sure that each ear can only hear what it is supposed to hear. If each ear can still hear what the other ear is only supposed to hear, it is no good. And now I will explain why. Okay as I said, our brains are just awesome. Let’s say we have a sound of 95Hz playing in the left ear. And, in the right ear, we have a sound playing at 102Hz. As I said before, if both ears heard both sounds, we may not even notice the difference. But…if we are doing it as I just explained, our amazing brains will hear a sort of, “Wah,wah,wah, wah…,” sound. Pull out one ear…well whatever you are using ear bud, phone, etc, and then the rhythmic pulsing will disappear! Why? Well… 102 minus 95 is… whoa! Remember that we said that something around 7Hz would be a good way to get us calm again? Well, the “wah, wah, wah,” sound is YOUR BRAIN noticing the difference between the 102Hz sound and the 95Hz sound! And 102-95=7! We have our 7hz! Because remember: Hertz is cycles per second, and the sound we now hear is like something spinning around and around and we only hear it when it comes closest. Change the right ear to 100, and BOOM! You will hear a sound 2 times every second. That is the same thing as once every half second. If 2 halves are always equal to 1, then it is one sound pulse each half second.
    Thanks for taking the time to read this 7 volume encyclopedia. LOL I love to talk about cool stuff in science but I don’t often get time or opportunity to. I will close with the most mind blowing part of this entire thing. This sound project (that is, figuring out that the brain could perfectly distinguish between what seem like two identical sounds, and if close enough, can tell the difference in Hz or cycles per second. I have trouble with higher than a 10 Hz difference, but that’s just me.) provided each ear can only hear one of each sound…it was discovered and proved to be true, real, and accurate way back in the late 1800s! Seriously, look it up. The worst part is that nobody bothered to do anything about it or with it for more than a century afterwards. Why? Mostly because of lack of confidence and belief in his work and ideas. Remember that some of the most successful people in the world have come from the most awful, depressing, dangerous and difficult circumstances. YES, it is going to be difficult. YES
    EVERY SINGLE PERSON has come dangerously close to just giving up. If you believe in something, if you have a heart and mind that won’t shut up about your passion for science, music and art (yes, you read it right, music and art is NOT stupid, NOT worthless, but it is harder in some ways) but if you believe, you can not only be happy yourself, but you can-and there is a decent chance that you will-save someone’s life through your art or music. Do it like YOU love it more than anyone else and you mean to prove that some day!

  3. Is theta brainwave state not also for mind programming?
    Many writers say that when the mind is deeply relaxed it accepts instructions easily.
    Theta is deeper than alpha, so if alpha is for mind programming, why have you not mentioned it for theta?
