Brain waves
Low electricity flows through the human brain and this flow can be changed, i.e. it can be influenced. Each of the brain's many billion neurones works like a small electric generator.
The first EEG was developed around 1920. It was then discovered that the human brain creates four different types of brain waves that are called, beta, alpha, theta and delta waves.

Beta-waves are the fastest brain waves and have a frequency range of between 14 Hz and more than 100 Hz. In our normal waking state, the brain produces beta waves. These waves are said to be related to attention, excitement, concentration, but also to fears and nervousness. We are mostly in the beta range in our daily lives; the attention is focused on the outside. The higher the frequency, the more hectic we get.  

  • Alpha waves are in the 8 to 13 Hz range, and slower than beta waves. The more we relax, the more alpha waves dominate our brain. This state is also called the “alpha state”. Alpha activity suggests a mostly neutral state in which we are not stressed. The lack of alpha activity can be a sign for worries and stress. The alpha range is considered ideal for learning or processing information.
  • Theta waves are even slower and stronger and are in the 4 to 8 Hz range. They occur in the in-between state between being awake and being asleep and are often accompanied by dream-like uncontrollable mental images. This range is considered to be ideal for creativity but reportedly also makes it easier to access unconscious memories or have integrative experiences.
    Adults normally only produce a few theta waves, while children are often in the theta state. They are even in this state most of the time until they are six years old. The theta wave range also dominates our brain in deep meditation.
  • Delta waves are in the frequency range below 4 Hz and are being produced when we are asleep. The delta state is associated with deep calm, our consciousness is asleep. Growth hormones are being produced in this state and this is  why some researchers associate delta states with healing.
  • No wave range is “better” than the others. However, studies have shown that during top performances, the activity of the brain reaches a state called “synchronization”.  Brain waves are waves with highs and lows. Synchronization is achieved if the brain waves reach the peak at the same time, i.e. synchronical. It seems that synchronization and the synchronization of the brain hemispheres are a sign for cerebral top performances, whilst asymmetric brain waves seem to be a sign of depression. 

Research work has shown that we can can influence our brain waves and thus our state.  People have been doing this for thousands of years. Certain drum rhythms of shamanistic ceremonies, but also colors, sounds movements influence our brain waves and regulate many biological functions. Michael Hutchison, author of many books on consciousness technologies, writes “The most important discovery of  brain evolution […] is that the state of our brain and our behavior are not beyond our control. We are not weak and helpless at all, we are not victims of our past or our environment. Neuroscience has proven it: We can change these states at will and quickly. He adds: “If we can change the state of our mind we can also change our behavior”.

Meanwhile, an experiment at Hahnemann Medical College in Philadelphia has already proven that rats can generate certain brain wave patterns at will.

Leonardo Pisano Bigollo (c. 1170 – c. 1250) also known as Leonardo of Pisa and Leonardo Pisano, was an Italian mathematician, who worked at Emperor Frederick II's court and wrote many papers on geometry and the theory of numbers. He discovered the laws of plant growth and showed that they are also valid in other fields of biology.

Human subtlety will never devise an invention more beautiful, more simple or more direct than does nature because in her inventions nothing is lacking, and nothing is superfluous.
Leonardo da Vinci

Leonardo Pisano Bigollo (c. 1170 – c. 1250) also known as Leonardo of Pisa and Leonardo Pisano was the son of a an Italian merchant from Pisa who did business with Arab countries. Fibonacci had Muslim teachers and traveled to Egypt, Syria, Greece and other countries. 200 years before the decimal system became common in Europe, he studied the Hindu-Arabic numeral system and the calculation methods developed by Arab mathematicians. With his most important book, the “liber abaci”, Fibonacci later introduced the 0 to the Occident. Fibonacci was a mathematician at the court of Emperor Frederick II and wrote numerous papers about geometry and the theory of numbers that were far ahead of his time. He discovered the laws of the growth of plants and found that this numerical concept is also applicable for other biological fields.

Pink Noise:
Pink Noise is a sound mixture of all frequencies audible for the human ear. The sound is similar to water noise. Pink Noise is said to connect the two hemispheres of the brain and create a relaxed state of mind. Robert Monroe has found that the effects of stimulating sounds and frequencies are increased if they are combined with Pink Noise, In the 50s, he did research on learning while sleeping and developed several tapes and CDs at the Monroe Institute in Virginia, which are called Hemi-Sync and are popular around the world today. Monroe used a mix of sounds and Pink Noise.

Pink Noise is also used for the treatment of tinnitus in academic medicine, among other things.


The saccule is a small bed of sensory cells situated in the inner ear. It contains a gelatinous liquid in which sand-like particles are swimming. If we shift our head or our body, the brain uses the movements of the particles to calculate the new situation in relation to gravity. Dr. Martin Lenhardt from the University of Virginia showed in 1991 that the skin can transfer sounds to the brain through the saccule. Patrick Flanagan's Neurophone has been using this fact for about 45 years.


Most of us will know ultrasound from medical applications. It can be used to examine the human body. The ultrasound is reflected differently from different tissues and this is used to create a picture.

Ultrasound, however, is a natural and common phenomenon, especially in the world of animals. Most of these animals mainly use ultrasound to transmit information (like the Neurophone). Most people know that bats, dolphins and whales use ultrasound.

Humans can only hear frequencies of up to about 20 kHz. Many animals, however, are able to hear in the ultrasound range (> 20 kHz). Dolphins, for example, use a series of short clicks with frequencies of up to 130 kHz. Scientists think that dolphins use a kind of signal-beam to communicate with each other and are therefore able to perceive the brain structure of the creature next to them. Dolphin therapies (such as Dr. Dave Nathanson's, who worked with handicapped children) also suggest that dolphins can use ultrasound to feel what is wrong with the patients and consequently adapt their energies.
