This process is explained briefly below.
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.
Here is a more modern EEG recording:
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 of mental state, but they can be stimulated to change a person's mental state, and this in turn can help with a variety of mental issues.
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 many other mental states, including concentration, creativity and meditation.
If you listen closely while using our software, you will hear small, rapid pulses of sound. As the session progresses, the frequency rate of these pulses is changed slowly, thereby changing your brainwave patterns and guiding your mind to various useful mental states.

A description will never do it justice. Brainwave entrainment just has to be experienced.
To get started using this technology is easy. All you have to do is download a brainwave entrainment program and play it from your computer. If you can't relax at your desk, try exporting to CD or an MP3 player.
This technology is safe, inexpensive and effective. And, trying it out is 100% free.
For beginners we recommend starting with the Neuro-Programmer software.
