Brainwaves Technology - Tame the Crazy Brainwaves

[Hadriel Sam]

Human brain is made of billions of cells, called neurons, Memory Hack Review   which communicate through oscillating electrical signals. These signals are very tiny - a few millionth of a volt. Combined together, there is an enormous amount of electrical activity in the brain. The sum total of these signals can be detected at the scalp by electroencephalogram (EEG). Because of the cyclic wavelike shape of the signal, the recording is called brainwave pattern.

Importance of brainwaves The electrical activity and hence the brainwaves change depending on what the person is doing. For example, during sleep brain sends off different signals than when awake. Further, a person who is anxious or tense will have a brainwave pattern that will differ from the pattern when he is calm and relaxed.

The brainwaves not only indicate the mental state, but they can also be induced to change. This, in turn, can help change the mental state. Change of brainwaves is achieved through what is called "entrainment". This provides a great handle to explore and exploit mental states that are rather difficult to reach - for example states of deep relaxation, meditation, or lucid dreaming.
