What are Brainwaves?

Your brain is made up of billions of brain cells called neurons, which use electricity to communicate with each other. The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment (such as an EEG), measuring electricity levels over areas of the scalp.

The combination of electrical activity of the brain is commonly called a BrainWave pattern, because of its cyclic, "wave-like" nature.

Below is one of the first recordings of brain activity.

The Significance of Brainwaves

With the discovery of brainwaves came the discovery that electrical activity in the brain will change depending on what the person is doing. For instance, the brainwaves of a sleeping person are vastly different than the brainwaves of someone wide awake. Over the years, more sensitive equipment has brought us closer to figuring out exactly what brainwaves represent and with that, what they mean about a person's health and state of mind.

You can tell a lot about a person simply by observing their brainwave patterns. For example, anxious people tend to produce an overabundance of high Beta waves while people with ADD/ADHD tend to produce an overabundance of slower Alpha/Theta brainwaves.

Researchers have found that not only are brainwaves representative of mental state, but they can be stimulated to change a person's mental state, and even help treat a variety of mental disorders. Certain Brainwave patterns can even be used to access exotic or extraordinary experiences.

Stimulating brainwaves with sound

Our sound tracks stimulate brainwaves in a variety of ways through a complex neural process known as Brainwave Entrainment.

What is Brainwave Entrainment?

Brainwave Entrainment refers to the brain's electrical response to rhythmic sensory stimulation, such as pulses of sound or light.

When the brain is given a stimulus, through the ears, eyes or other senses, it emits an electrical charge in response, called a Cortical Evoked Response (shown below). These electrical responses travel throughout the brain to become what you "see and hear".

When the brain is presented with a rhythmic stimulus, such as a drum beat for example, the rhythm is reproduced in the brain in the form of these electrical impulses. If the rhythm becomes fast and consistent enough, it can start to resemble the natural internal rhythms of the brain, called brainwaves. When this happens, the brain responds by synchronizing its own electric cycles to the same rhythm. This is commonly called the Frequency Following Response (or FFR):

FFR can be useful because brainwaves are very much related to mental state. For example, a 4 Hz brainwave is associated with sleep, so a 4 Hz sound pattern would help reproduce the sleep state in your brain. The same concept can be applied to nearly all mental states, including concentration, meditation, creativity and many others. It can even act as a gateway to exotic or extraordinary experiences, such as deep meditation or "lucid dreaming" type states.

Theta

There is a certain theta brainwave state which makes absorbing a new language extremely easy. As babies and young children we are often in this Theta state naturally but as we grow older we access it less and less. In this state important neuro chemicals are released in large quantities which are vital for the learning of new information. It actually makes your brains chemical make up far closer to that of a babies brain.

When you learn new information in Theta it goes straight into long term memory, effectively bypassing the usual filters that slow down retention. In the usual state of consciousness learning a language is extremely slow because it is short term memory that is used.

Our technology induces the exact brainwave state needed for rapid learning of a new language. It is extremely precise and very powerful technology.
