Brainwave Entrainment Definition

By Joshua Graham


There is a neuro-scientific technology available today, that has been used successfully by the medical-scientific community for over the past 70 years, in the area of healing, and it is called brainwave entrainment.This neuro-technological tool, is specifically designed, portable, convenient, and very effective in the areas of self-healing, cognitive function improvement, augmentation with traditional psychological therapies, the stimulation of hormones and pain relievers, and the enhancement of relaxation, making it the panacea for today's stressed-out, busy lifestyle.
[Brain Entrainment]


What is Brainwave Entrainment? Brainwave entrainment is a deliberate process that synchronizes, or entrains natural brainwaves to that of an external stimulus frequency, that is usually auditory and/or visual in nature. When the brain entrains, it duplicates the frequency of the stimulus, causing a change in the electrical activity in the brain. Each different electrical response produces a different brain state or brainwave frequency. Each different brainwave frequency has a specific pattern and can be designed to induce a certain effect or state of consciousness.

Brainwave Entrainment Fundamentals.A common reason of why many people doubt the effects of brainwave entrainment is because the term itself sounds a bit scientific and incomprehensive. That's why we should look at some real life brain entrainment examples. You are probably asking yourself... What? Yes, the brain is meant to adapt, and it quickly changes its state, according to the surrounding environment. Let's take a look at this - when one first wakes up in the morning, they still feel rather sleepy (as their brain has been in a state of sleep); if, however, they look out of the window and see a fire burning in the next building, they will become very alert - the brain has quickly entrained itself to this new state. On the contrary, if the same person goes to a room full of sleepy people, it is likely that they will stay in this same state unless they do something different (make a cup of coffee, go out, etc.).

When the brain is exposed to a frequency, it undergoes a Cortical Evoked Response, where it emits an electrical charge in response to the stimulus. The predominant brainwave frequency is said to move towards the frequency of the stimulus, matching its frequency.Pulses and patterns of neural activity move through the brain in waves in a dynamic ocean of subtle electrical matter at all times. These patterns of electrical activity are called brainwaves and are responsible for different states of consciousness.

To understand how binaural beats, monaural beats, and isochronic tones can improve your overall well-being at a physical, mental, emotional and spiritual level a basic understanding of the electrochemical functions of the brain is necessary. Our brain is made up of billions of brain cells or neurons which use electricity to communicate with one another. The combination of millions of neurons sending signals all at the same time produces an enormous amount of electrical activity in the brain. This activity can be detected and mapped using EEG devices. Such mapping shows that the brain is emitting specific frequency brainwave patterns that relate directly to different mental processes all the way from wide awake and highly focused (beta) to deep, dreamless sleep (delta).Following are the 4 most common brainwave classifications as revealed by EEG devices. The brain is a dynamic, living organ. During these dominant patterns, other frequencies still exist and there is no exact, single frequency that our brain operates on.Frequency range Name Usually associated with:13 to 40 Hz Beta waves Active, busy or anxious thinking and active concentration. Throughout the day our brains are in the beta range. At this level we are active, busy, and all our emotional responses are at this level whether we are depressed, irritable, angry, happy, glad, full of energy etc.7 to 13 Hz Alpha waves When we begin to relax or begin to get drowsy, but are still awake and conscious (maybe at pre-sleep) we are said to be at the alpha level.4 to 7 Hz Theta waves Dreams, deep meditation, hypnosis.Defining Binaural Beats, Monaural Betas, and Isochronic Beats.Binaural Beats - Binaural beats require headphones if you want to see results. Binaural Beats work by broadcasting two separate frequencies in each ear. For example, if you want to tune your brain to a 7 Hz frequency, you could play 200 Hz in your right ear, and 207 Hz in your left ear. The brain will compensate for the difference between the two and produce a third tone that will be exactly 7 Hz. This will result in your brain frequency being lowered to the theta level of 7 Hz.Monaural Beats - Monaural beats are the opposite of binaural beats because the input is the same in each ear therefore you don't need headphones but good speakers are always a plus. In the case of monaural beats the sound is the same on each side whether you use headphones or speakers, but the volume must be tuned precisely (not too loud and not too low) for the beats to be effective.

Isochronic Tones - These are sharper sounding than monaural beats thus they are more powerful in their effect on the brain and are believed to be the most effective of the three.Binaural beats, monaural beats and isochronic tones by themselves are not very pleasant to listen to. This obstacle is overcome by embedding these beats/tones into soothing ambient music, nature sounds, the sounds of bells or chimes and so on.Is Most Brainwave Entrainment Music Dull And Monotonous? One thing you will notice right away about most brainwave music is it's usually made up of slow tempo ambient music, or new age meditation music, and sometimes classical orchestra music. And it is sometimes embedded with background noises such as static noises (white noise, brown noise, pink noise), or with nature sounds like that of birds, waves/ocean, rain, wind, thunderstorms, and also bells, chimes, flutes, and so on. In every case the important part of the music is the background beats (whether binaural beats, monaural beats, or isochronic beats) which need to be perceived by the brain throughout the recording otherwise it will be ineffective. All the other added stuff (ambient music, nature sounds, bells, chimes etc.) is only for the sake of making the background beats pleasant to listen too. If the music is very fast pace, such as in rock or pop music, or too loud the background binaural, monaural or isochronic beats are drowned out and not effective in entraining the brain.

It takes 8 to 10 minutes to begin entraining. Because binaural beats don't entrain the thalamus, most of its effectiveness is in dissociation, making them good for meditative states, altering subconscious messages, and pain.MONAURAL BEATS-two tones are combined to create a perceivable beat, are played in each channel, resulting in a stronger stimulus because they mix together before they reach the ear. This form of entrainment is stronger than binaural beats but can be altered by outside noise interference.ISOCHRONIC TONES-the strongest, most effective entrainment uses pulsing tones to synchronize the brain to a desired frequency. The process is automatic and requires no particular effort or focus from the user. Distinct sharp tones are introduced to the brain, which the brain easily follows, causing a strong entrainment. Tones entrain in the thalamus and are very effective for deep meditative states, mild relaxation, high level stimulation, and cognitive enhancement because they cause the brain to form new neural networks. The entrainment effects are fast and permanent.

After several months of regular daily use of the same brainwave recording your mind gets accustomed to the stimuli and it becomes 2nd nature, giving the impression that the recording doesn't work anymore. The reason is your mind is strengthened in once neglected areas as new neural pathways are created and adjusted to the recording. Working your mind with brainwave recordings is similar to working your muscles. After a time a certain muscle, for example, no longer seems to be receiving any benefit from the same exercise which initially seemed very effective. The reason is the exercise served its purpose in bringing the muscle to its present much more healthy condition. The only way to add additional benefit to that muscle is to change the exercise around a little. This will produce long-term benefits. Likewise your mind gets stronger with time as you listen to brainwave recordings, but it reaches a point where a particular recording which once seemed so effective appears to be doing nothing anymore. However, if the recording is changed around a little it will produce additional, long-term results. And just as having a variety in your exercise routine, and even a variety in your diet, is better for your body. So likewise you will receive long-term benefit, and a more balanced mind, by listening to a variety of brainwave entrainment recordings.For this reason some companies sell several CD recordings contained in one program with specific instructions on when to listen to certain recordings, and for how long, before switching to the next level of recordings. They do it this way so you receive the optimal benefits the recordings offer. And just as it is not a good idea to stuff yourself with a variety of different foods at once, or to exercise too much all at once, so likewise it is good to start with one level of recordings, giving your mind time to adjust to that recording before moving to the next level.
