Brainwaves have been altered in many ways over the centuries using many different methods. Africans and North American Indians have done it with flickering fires and drum beats, usually to obtain a state of excitement and violence associated with a battle. In the East it has been used to cause a religious fervour usually with music and girating.


In the modern era and the advent of electronics it is very easy to alter the brain waves, now we know their frequency. Below is a list of these frequencies and their uses and effects.


There are quite a few ways these waves can be altered, the main being visual and acoustic. The visual method can easilly be done by feeding the output of the brainwave monitor to some LED`s set into a pair of glasses. The acoustic method requires only headphones to be plugged into the monitor. Deap relaxation can be obtained by using the feedback as an indicator to lower your beta waves. Deap trance states can be obtained with training. The reverse can be done by increasing the rate of certain waves to cause excitement. Nausea and vomiting can occure when these waves are taken to the extreme.

Your body is filled with electrical impulses that can be used as communication. This circuit although quite old, still works after 20 years. The gain of this little op amp has a gain of 300,000 which is able to drive a transistor amplifier or radio. It was originally wired straight onto the volume control, but can be fitted with a jack plug and used in the microphone input of any amplifier. Just be careful that there are no high voltages on this input, if possible use a battery operated amplifier. The electrodes are small copper coins with flexible leads soldered on. Sometimes using a piece of cloth soaked in salt water and wrapped around the coin improves the contact.


Placement of the electrodes on the body is important; usually they should be 100 mm apart across a muscle. Contract the muscle and you will hear what sounds like static. To listen to your heart place the electrodes 130 mm apart on either side of your heart.

I also still have the brain wave monitor working, which was an improvement to this circuit with filters for the Alpha and beta waves of the brain.

With the brain wave monitor other filters were fitted on a rotary switch, 5 in all, with the 6th one used for pulse.

Biofeedback was the next step and a audio output was fed from the monitor through headphones to the subject wearing the electrodes. They were then able to control their beta waves and relax more.
