Mind control may seem like something from the realm of scientific discipline fiction or a superhero movie.

While onscreen, it is portrayed every bit an alien or futuristic technology, usually accompanied past evil intentions for power and control, human beings are actually on the verge, or at least on the right path to alter encephalon waves to suit our diverse needs, merely with less sinister intentions.

While going through a stressful situation or trying to tackle a risky manoeuvre, what if there was a manner to control our thoughts, feelings, and emotions, or the encephalon in full general, to modify mental states to the desired wavelength to manage the situation better?

This can be brought about by changing or strengthening brain wave patterns, past external cues or stimuli.


Highlights:

  • The theory behind encephalon waves and how they work.

  • Neurofeedback and how information technology works.

  • Neuro-audio and how they influence brain waves.

  • How people can use neuro-sound to their benefit.

Before nosotros move ahead, let us first clearly establish what exactly are encephalon waves and their frequencies. The brain is made up of several specialized cells called neurons.

Neurons constantly interact with each other in the brain through an electrical activity that tin be measured using a technique called EEG or electroencephalography.

Using sensors fastened to the scalp, scientists can tape the electronic feedback and map them out like waves.

Each homo activity corresponds to a different wavelength.

For example, a brain moving ridge measured and mapped out while nosotros’re resting will differ from when it’s mapped out while we’re in a focused state. Brain waves also occur at various frequencies. While some are fast, others are slow, based on our activities and emotional states.

Now, these brain waves tin can be divided into broad categories, based on their wavelength and frequencies.

v Types Of Band Waves For Brain

The most widely used names for EEG bands are Delta, Theta, Alpha, Beta and Gamma. They are measured in a cyclic format, or cycles per second called Hertz (Hz).

  1. Delta

    Delta (1-3Hz) brain waves have the slowest frequency and the highest amplitude. We experience Delta brain waves while we are comatose.

  2. Theta

    Theta (4-7Hz) brain waves indicate a dreamy, relaxed state, usually attained during meditation, stress-complimentary relaxation. Information technology usually represents the twilight zone betwixt sleep and wakefulness.

  3. Blastoff

    Alpha (8-12Hz) brain waves are slower and larger, associated with normal relaxation while waiting for external stimuli to touch it. If nosotros shut our eyes and relax, picturing peaceful scenes, there is an increase in alpha brain wave activeness. It is the idle or neutral gear of brain waves.

  4. Beta

    Beta (thirteen-38Hz) brain waves have a faster and shorter frequency associated with levels of concentration or mental and intellectual activity. It represents a state of alacrity.

  5. Gamma

    Gamma (39-42Hz) brain waves are faster blips of subtle vibratory states, normally associated with regulating perception and consciousness.

Normally, nosotros cannot alter brain wave patterns every bit we’re ordinarily not enlightened of the state they’re in.

All the same, we tin easily influence them. When nosotros learn about the different encephalon wave states mentioned above, through proper external conditioning, we may be able to exert enough influence, and through abiding try.

The changes become gradually enduring, with the feedback matching the influence. This practice of influencing encephalon waves to reach certain states is termed Neurofeedback.

Neurofeedback is a form of alternative handling wherein brain waves are retrained through auditory or visual stimuli, such as using music or watching videos, to influence brain waves according to our desire.

This technique is non-invasive, i.e, there is no usage of medicine, also proving to be extremely cost-effective. Through neurofeedback, we can boost attention, heighten retentiveness and creativity, and besides promote communication skills.

It can additionally exist used to treat feet, and depression and promote a ameliorate quality of sleep likewise. Numerous

case studies

tin can attest to this.


music for relaxation

Neuro-sound is a form of neuro-feedback wherein auditory stimuli, such as music, binaural beats or positive affirmations are utilized to influence encephalon moving ridge chemistry, to our desired effect.

Neurosound can be used to achieve better brain health, learning abilities, as well every bit enhanced noesis.

While the term neuro-sound is a relatively new term in the realm of science, the do of using sound and vibrations to influence our physical and mental wellness has been around for ages.

Right from Native American rhythmic drumming, to the Gregorian chants used in churches, sound and music have had a smashing impact in promoting health and healing.

Therefore, neuro-sound is the practice of how music and sound can affect our brain waves, thereby, impacting our physical and mental well-existence.

In our modern world, through the usage of science, we can excerpt the particular waveform or vibration from music or audio, isolate it, and so directly apply it for maximum benefits.

One such science of audio in the realm of binaural beats, first theorized in the twelvemonth 1839 by Heinrich Wilhelm Dove and tested and proved scientifically by Dr Gerald Oster, a medical dr. and biophysics, in the yr 1973, in his research newspaper Auditory Beats in the Brain.

These studies opened up a whole new avenue within the realm of neurofeedback and showed that sound tin can be effectively used to influence brain waves.

Now, allow the states look at how exactly Binaural Beats affect our brain and the scientific discipline backside it.

Dr Suzanne Evans Morris states that when two dissimilar frequencies are played through each earphone, left and right, the difference between them determines the brain wave beingness influenced.

For example, If a frequency of 210 Hz is played through one earphone, and 200 Hz through the other, the brain experiences a encephalon wave in the divergence between them, which is x Hz in the Alpha zone. The result of this is chosen “Brainwave Entrainment”.


Bowl music to help brain wave frequency

Hence, when brain waves can be influenced to a certainly required frequency corresponding to the five zones, brain part can be modified using sound.

Thus, certain frequencies, sounds and music have the ability to stimulate the encephalon, to fifty-fifty produce neurotransmitters such as serotonin, which is the “feel good” chemic messenger, which tin can be utilized to increase pleasure and reduce feelings of pain.

Dissimilar brain wave patterns are linked to the product of various neurochemicals which are associated with creativity, memory, relaxation, stress relief, increased learning, and other such desirable benefits.

An experiment conducted by Dr Margaret Patterson and Dr Ifor Capel showed how a 10 Hz brainwave frequency increased the production of serotonin, easing pain and initiating relaxation.

They also show how a four Hz brainwave frequency helps the encephalon to produce catecholamines, chemicals important for memory and learning.

Just put, the brain’due south internal advice system, or its
language,
is based on frequency, and when we speak this linguistic communication by influencing external frequencies through music and sound, we’re essentially able to communicate to the encephalon, initiating the desired mental state.

The Impact Of Stress On Metabolic Health

Neurofeedback and neuro-audio have far-reaching applications in our lives.

Several applications that can beneficially affect our lives, including

  1. Reducing stress.

  2. Relief from headaches.

  3. Hurting relief.

  4. Increased memory and learning.

  5. Preventing or reversing cognitive disorders similar Parkinson’s or Alzheimer’s.

  6. Promoting amend sleep cycles, recovery from addiction.

  7. Enhanced cognitive abilities.

Synchronisation of the two hemispheres of the brain, through neurofeedback, also enhances overall well-being and motor reflexes, due to faster and better flow of communication betwixt the two halves of the brain.

In terms of the 5 bands of encephalon waves, listening to Alpha brain waves helps a person to relax and de-stress, while besides increasing the production of serotonin.

Additionally, Dr Georgi Lozanov has shown that students in the Alpha encephalon wave zone can absorb equally much equally 5 times more than information, in less time, with increased memory retentivity equally well.

Theta brain waves can be used to sync the 2 hemispheres of the brain, thereby increasing the faster flow of communication.

Most classical music is in the Alpha or Theta zone while most metal or hard rock music is similar to a high Beta state indicating increased awareness, but are too stressful.

One tin can use the Delta frequency to autumn comatose easier, and besides repair and recover quicker from injuries or daily concrete stress. Sleeping aids made by pharmaceutical companies prevent the torso from making certain neurotransmitters and destroy encephalon part over time.

In contrast, neuro-sound is not-invasive, merely influencing encephalon states similar to sleep and calm, making it easier for the states to fall asleep.

Conclusion

if we can assistance a person to initiate different brainwave states consciously, we are facilitating an individual’s power to allow more patterns or variations in their brains, thereby, making changes at a neural level.

This tin help them “shift gears” in life, as required, through the usage of sounds and music. Make sure you are witting and educated about the frequency the music or sound is emitting, and use it to your advantage to change your country of listen.
