Examples of possible uses for brain stimulation
o Relaxation and meditation by entraining your brain into desired states
o Enhancement of learning capabilities (super learning)
o Sleep induction (for treating insomnia or just for falling asleep quicker)
o Focusing attention and enhancing awareness
o Alleviation of headaches and migraines, as well as other pain
o Preparation for stressful situations
o Self hypnosis and/or subliminal programming
SKEPTICISM WARNING
Some people also claim that the following might be achieved with brain stimulation. However, there is no direct scientific proof of any of these, so a bit of a skeptical attitude is recommended.
o Enhancing psychic capabilities like tendency towards out-of-body experiences, remote viewing, telepathy, telekinesis, etc.
o Mental and astral projection
Requirements
* Microsoft Windows 95/98/ME, or Windows NT/2000/XP operating system
* At least 90 MHz Pentium processor. The faster the processor, the more complex output BrainWave Generator can produce.
* A stereo-capable sound card.
Warning WARNING!
The following people should not use brain entrainment products like BrainWave Generator:
* People subject to any forms of seizures or epilepsy
* People using pacemakers
* People suffering from cardiac arrhythmia or other heart disorders
Features Of BrainWave Generator
o Possibility to create and save your own brainwave entrainment presets with a very easy-to-use user interface. A context-sensitive online help is also included.
o More than 20 built-in presets ranging from sleep-induction to headache alleviation.
o Brainwave entrainment presets can be exported as files and imported back, so that exchanging presets between different users becomes very easy. (Importing is only available in the registered version.)
o NEW! Instead of playing, output can also be saved into a .WAV file. This allows you to further convert the .WAV to MP3, or store it onto a CD.
o Selection of 18 different background sounds ranging from gently flowing river to roll of thunder. External .wav files can also be used as backgrounds.
o Possibility to use noise as the background. The noise can be smoothly varied from "harsh" white noise to "gentle" brown noise and anything in between. Noise smoothness is a parameter which can be programmed just as any other parameter, like the binaural frequency.
o Brainwave entrainment presets can be of any complexity. Parameters such as binaural beat frequency, volume, audible pitch, modulation, waveform and background can all be individually programmed. Parameters can also be set to track each other. See the screenshot below for an example.
Preset Options Screenshot
o Possibility to add up to 10 simultaneous voices to the output. For each voice, parameters such as binaural beat frequency, volume, audible pitch, modulation and waveform, can be programmed separately.
o Brainwave entrainment presets may consist of several segments, each having their own length and separate set of parameters. By specifying the first segment as a long silent segment, you can time the actual output to start any time you want.
o Possibility to play CD's or MIDI files on your sound card at the same time while listening to binaural beats. Requires external MIDI/CDapplications to be used at the same time with BrainWave Generator.
* People taking stimulants, psychoactive drugs, or tranquilizers
Theory Behind BrainWave Generator
EEG and the brain's state
EEG (Electroencephalography) technology is used to measure brain's electrical vibrations from the surface of the scalp. The resulting EEG pattern will contain frequency elements mainly below 30Hz.The frequencies are categorized into four states as follows:
State Frequency range State of mind
Delta 0.5Hz - 4Hz Deep sleep
Theta 4Hz - 8Hz Drowsiness (also first stage of sleep)
Alpha 8Hz - 14Hz Relaxed but alert
Beta 14Hz - 30Hz Highly alert and focused
The dominant frequency in the EEG pattern determines what shall be called the current state of the brain. If the amplitude of the alpha range frequencies is highest, then the brain is said to be in the alpha stage. Note, that other frequencies still exist and it is impossible to give any "exact frequency your brain is operating on". However, later references to the brain states use the simplification of assuming that such a singlefrequency exists.
Entraining the brain to a desired state
If external stimulus is applied to the brain, it becomes possible to entrain the brain frequency from one stage to another. For example, if a person is in beta stage (highly alert) and a stimulus of 10Hz is applied to his/her brain for some time, the brain frequency is likely to change towards the applied stimulus. The effect will be relaxing to the person. This phenomenon is also called frequency following response.
When the brain's state is close to the applied stimulus, entrainment works more efficiently. Thus, when doing a sweep from one frequency to another, the starting frequency should be as close to your current brain state as possible. The sweep speed should be such that your brain's state changes steadily with it, so that the difference never gets very large. In practice, it is difficult to determine your brain state without extraequipment (like EEG devices). However, you can quite safely assume that during the day your brain is in the beta stage (about 20Hz) and you can start the sweep from there. If you are already somewhat relaxed, you can use a start frequency of 15Hz or a few Hz lower.
Stimulating the brain with binaural beat frequencies
The easiest way of applying stimulus to the brain is via ears. Other senses could be used as well, and vision is actually used quite often (often in addition to hearing). However, humans cannot hear sounds low enough to be useful for brain stimulation, so special techniques must be used. One such special technique used is called binaural beats.
If the left ear is presented with a steady tone of 500Hz and the right ear a steady tone of 510Hz, these two tones combine in the brain. The difference, 10Hz, is perceived by the brain and is a very effective stimulus for brainwave entrainment. This 10Hz is formed entirely by the brain. When using stereo headphones, the left and right sounds do not mix together until in your brain. The frequency difference, when perceived by brain this way, is called a binaural beat.
The effect of the audible frequencies used
To get a stimulus of 10Hz, you may use tones of 500Hz and 510Hz, or 400Hz and 410Hz, or 800Hz and 810Hz, or so on. The only requirements are that the tone is heard well enough and that it is below about 1000Hz. Below 1000Hz, the wavelength of the skull is sufficiently small so that the sound waves curve around it.
You may try out different audible tones with BrainWave Generator and see which ones work best for you.
Altered brain states
As mentioned above, applying a stimulus to the brain will eventually bring the brain's state closer to the stimulus frequency. The following paragraphs describe some possible effects of this.
Note, however, that just passively listening to binaural beats does not necessarily alter your state of consciousness. For example, willingness and ability to relax and focus attention affects how effective the binaural beat stimulus is for inducing state changes.
Helping in meditation
Meditation is essentially about willingly being able to alter one's brain frequency to a desired state. While meditators have traditionally used several years to learn the techniques of meditation, you can now attain the same effect with brainwave entrainment. No special training or great discipline is required. Good meditation frequencies are in the alpha range, from 8Hz to 13Hz.
When a certain brainwave state is experienced and practiced over a period of time, the brain will "learn" the state change and it will become easier to self-produce the desired brainwave state at will. Thus, using brainwave entrainment, you can expect to get some of its effects later even without any entrainment.
Reducing learning time
The theta stage (4hz - 7Hz) has been found to increase learning capabilities. In fact, children spend more time in theta stage than adults, which probably explains the accelerated learning capabilities of children.
Alpha frequencies are also useful for learning purposes. You can play language cassettes, subliminal tapes, etc. during an entrainment session for a maximum effect.
Reducing sleep needs
Some people have found that half an hour a day of the Theta stage can replace up to 4 hours of sleep.
Treatment of certain mental diseases
Brainwave entrainment is used in treatment of depression, low self-esteem, attention deficit disorder, drug and alcohol addiction and autism, to name a few.
Brainwave entrainment has also been found helpful in alleviating headaches and migraines.
Miscellaneous
Some users have also reported increases in their sex drive as a result of brainwave entrainment.
