Brainwaves are the measurable result of your brain activity and are said to be discovered by German neurologist Hans Berger in the mid-1920s. Berger’s path to this discovery originally began because he wanted to record what he thought was psychic energy in the brain and through his work successfully made the first recording of electrical waves in the brain: an electroencephalogram, or EEG.
Since his discovery, EEGs have been used to provide useful information about one’s mental state and functioning, as they can lead to the diagnosis of various ailments such as epilepsy, sleep conditions, Alzheimer’s and other issues related to brain functioning.
EEG works by connecting electrode sensors to the scalp. These sensors measure voltage fluctuations from ionic current flows within the neurons of the brain. The frequencies of this activity can me measured and monitored.
The activity measured using EEG can be very detailed and complex, and dependent on the area of the brain, but most people are familiar with some of the 5 general different levels of activity we can find in the image below:
You can see each category has a different band of frequency range as the brain carries out its different functions.
Brain waves are relevant to our mental health, as inbalance in brain functioning can influence the development of certain conditions. When certain areas of the brain are over-aroused an individual may experience anxiety, nightmares or other sleep problems. It can also manifest as impulsivity and aggression. Too little arousal in the brain has been correlated with depression, chronic pain and insomnia. If brain rhythms are unstable an individual may experience obsessive compulsions, develop epilepsy or have panic attacks.
In simplified terms the brain is the central processing unit of the human body. It monitors and controls the production of sound for the whole body. It monitors from within the body and all outside external influences on the body.
It is extremely active sending out and receiving all the signals to maintain the body and mind in harmony as best it can. In today’s busy and complicated world it can be a particularly stressful task.
Like all computers the brain can suffer from corrupted memory access and data processing. It can sometimes forget how to order up certain frequencies or when it does remember, communications lines are disrupted by internal or external influences resulting in the commands not reaching their destination or the instructional messages suffering some sort of ‘Chinese whispers’ effect to convey slightly wrong information.
The brain, and ergo the body and mind, can be reminded or corrected by giving it three different types of frequency choice in the form of Sound Therapy: Frequency Entrainment, Harmonic Entrainment or Sympathetic Resonance. All three are incorporated in BioTuning Sound Therapy.
