I am presenting you a very interesting effect of sound on our brain. To keep myself short in this introduction I will just demonstrate the effect (it will take 24s of your time, and trust me, it will be really interesting :). All you are going to need are earphones: you will not hear the effect if you don't use earphones (you can't use speakers - I'll explain why latter :) First, listen this 6s long audio with only 150Hz frequency tone:       

Now, listen an another 6s long audio with only 151Hz frequency tone:       

And now, the interesting part. :) Listen the next audio - it's also 6s long, but it will give you sound with frequency of 150Hz on your left earphone and sound with frequency of 151Hz on your right earphone (I told you that you'll need earphones ;). While you listen this audio your brain will hear a new, pulsating sound: the new sound will pulsate with frequency of 1Hz (it will actually pulsate with a frequency that is equal to difference of the frequencies that are used for the stimulation, in this case: 151Hz-150Hz=1Hz).       

For the end of the demonstration listen an audio that will give you sound with frequency of 150Hz on your left earphone and sound with frequency of 152Hz on your right earphone: this will result that the third sound that brain hears will pulsate with 2Hz - notice while you're listening that it is pulsating twice faster.       

Further on, I will explain why this is happening and why this type of signals is very important to the brain (this is why we can figure where a sound is coming from). Also I will show you how this phenomena is related with achieving different states of conscience (the whole brain actually becomes synchronized with this frequencies what can be used to control it): from concentration and active thinking over relaxation to deep meditation (depending on what sound frequencies you chose) and I will present you little software that you can use for the sound brainwave stimulation. At the end, for those who want to learn more about this phenomena I prepared a little list of papers published on this topic in scientific journals

If you want to purchase a lie detector, also known as polygraph you must notice that it is not really easy to find something cheap, but still very accurate. 

 There are many lie detectors based on voice stress analyzation, but those detectors has very poor detection quality (I will put a several papers from science journals that proofs that this methods are not accurate at all). 

Serious lie detector (that are used for example in police stations) are based on following parameters:

If you don’t like the idea of someone “talking” to your sub consciousness (in spite of me convincing you of its harmlessness), but you want to use many advantages of the hypnosis, the solution is self hypnosis induction. Standard method for self hypnosis induction is to use mp3 tapes with hypnosis suggestions, there are lot of specialized tapes for e.g. weight loss or stop smoking etc. But this way of hypnosis is not really effective because mp3 tape doesn’t know when you really are hypnotized and when it should start with suggestions - it depends from person to person (suggestibility, concentration, power of visualization etc.). I am working on biofeedback self hypnosis - the hypnosis method where you using taped instructions, but you are also connected with computer which measures you brain wave frequency and indicates your state of mind. Computer controls taped instructions and gives you just the instruction you need at the specific moment. I believe that this approach will make revolution in self hypnosis area.

I am presenting you my little program integrated in this web page compares number you insert with random number generated by computer. You can register (free, very simple - no e-mail needed) and have your own statistics. Global and all individual statistics are available and visible to everybody.

Up to this moment more than 1000 users registrated and did around 20000 tests.

Lucid dreaming is conscious dreaming, with reference to dreaming where person who is dreaming is aware that he dreams, and that he can use it for control his dream.
Most of time which we achieve in a dream when we sleep, is characterized by REM phase brain waves. Attribute of the REM phase is winking eyes. Device that I presented here has eyeglasses with source of light and receiver of infrared light. Infrared light is focused to shutter, so change dose reflected of light detected wicking.
When arrangement detects REM phase of dream, it abandons configurable acoustic signals, which have part to warn person who is dreaming on that he is dreaming, and so bring him in phase of lucid dream.

Beside the acoustic brainwave stimulation (basic brainwave stimulator theory is explained in brainwave stimulator session so I am highly recommending you to take a look at it before reading this part) brain stimulation is possible with light too. Combination of acoustic brainwave stimulator and light brainwave stimulator is also very possible.

Electroencephalogram (EEG) is a device that amplifies and displays brain electrical potentials.
Every EEG consists of brain electrical potentials amplifier, digitalization (conversion of analog signal to ones and zeros – binary numbers) and displaying of data. Based on this model, and some useful advices from openEEG project I developed an EEG system, let’s analyze each part separately (to completely understand this section you need some basic electrical knowledge). 

There are about 13 billion neurons in human brain; they are communicating using electrochemical connections.

An ancient method of bringing a person (works with animals as well) in a state in which all somatic senses are eliminated.

Only a part of human brain stays awake - the part in charge of understanding the hypnotist’s speech. Maybe not precisely understanding, but recieving vocal orders directed to subconsciesness, which pass by the control of reason (that is why some people, for example, bark if the hypnotist tells them to).
