An electroencephalogram, usually abbreviated EEG, is a medical test that records electrical activity in the brain. During the test, the brain's spontaneous electrical signals are traced onto paper. The electroencephalograph is the machine that amplifies and records the electrical signals from the brain. The electroencephalogram is the paper strip the machine produces. The EEG changes with disease or brain disorder, such as epilepsy, so it can be a useful diagnostic tool, but usually must be accompanied by other diagnostic tests to be definitive.
To perform an EEG, electrodes, which are wires designed to detect electrical signals, are placed on the cranium either by inserting a needle into the scalp or by attaching the wire with a special adhesive. The electrodes are placed in pairs so that the difference in electric potential between them can be measured. The wires are connected to the electroencephalograph, where the signal is amplified and directed into pens that record the waves on a moving paper chart. The tracing appears as a series of peaks and troughs drawn as lines by the recording pens.
Basic alpha waves, which originate in the cortex, can be recorded if the subject closes his eyes and puts his brain "at rest" as much as possible. Of course, the brain is never still, so some brain activity is going on and is recorded in waves of about six to 12 per second, with an average of about 10 per second. The voltage of these waves is from five to 100 microvolts. A microvolt is oneone millionth of a volt. Thus, a considerable amount of amplification is required to raise the voltage to a discernable level.
The rate of the waves, that is, the number that occur per second, appears to be a better diagnostic indicator than does the amplitude, or strength. Changes in the rate indicating a slowing or speeding up are significant, and unconsciousness occurs at either extreme. Sleep, stupor, and deep anesthesia are associated with slow waves and grand mal seizures cause an elevated rate of brain waves. The only time the EEG line is straight and without any wave indication is at death. A person who is brain dead has a straight, flat EEG line.
------- The headset have EEG chips cost 90 USD, it support logging, I can add 3rd party software or directly build into the wireless receiver .
Function such as : Mind Training , Photo Memory, Mind activities, Speed Reading, the most important one - MONITOR YOUR OWN MIND, Possible with this device
An other hints for application of this device - use appz call "BrainWave Generator ", it can help you "sleep less", "quiet smoking", ...................emmmmmm...............I guess the application itself is unlimited!!!!!!!!!
The most economic commercial device would cost you at least 5K USD, with this tiny device, you can search you...... the one inside of you, the one you really try to understand , once u got there, u can make change of yourself |
