Brainwaves, Brainwave frequencies and Brainwave patterns

What are brainwaves? And how you may influence it using brainwave music? To explain this, we have to cast a more detailed glance on the function of our brain.

brainwaves

The human brain contents of four parts: cerebrum, cerebellum, diencephalon and brainstem. Scientists further divide every part of the brain. Nevertheless, for understanding the mode of operation of brainwave music this rough description is sufficient. Cerebrum and cerebellum are separated into two halves, the so-called hemispheres. Both hemispheres of the cerebrum are connected with each other by the corpus callosum, a very thick nerve fibre. The hemispheres of the cerebrum are responsible for certain tasks regarding body functions and mental action. The left hemisphere mainly supports our rational life, the right one is responsible for our intuition, emotions and creativity. Our brain contains of a great number of linked neurons, which communicate with each other by electrics impulses. These impulses create electric oscillations within the brain, the brainwaves. You can measure brainwaves of different frequencies in the human brain at the same time, due to the fact that the brain has to coordinate several tasks in parallel. Nevertheless, waves of one frequency band normally dominate according to the respective action one takes or the state of consciousness of the individual. These waves are measured with an Electroencephalograph (EEG).

Within its lifetime the human brain produces brainwaves at any time. Every thought and move, may it be performed consciously or non-consciously, creates brainwaves. Therefore, brainwaves can be influenced and stimulated intentionally by acoustic or visual stimulus.

Depending on the state of consciousness brainwaves are classified mainly in Beta, Alpha, Theta, Delta and Gamma frequency bands. The several bands are scaled in different Hertz-units (Hz) by the EEG. One Hertz corresponds to one wave per second.

Limits of waves, which a human ear may notice, as well as limits of the respective frequency bands are defined differently according to various sources. For the following explanations the limits given at Wikipedia have been used.

Beta-frequencies

Brainwaves, which are created by stimulus outside the body at the conscious phase of an individual, are called Beta-frequencies. They cover waves between 12 to 38 Hz. Humans are fully awoke and active. The more concentrated a human works the higher the beta-frequency rises. Brainwaves of someone working without stress cover the frequency band between 12 to 15 Hz, humans being stressed produce brainwaves at 21 to 38 Hz.

Alpha-frequencies

Brainwaves coming up during the transition period of sleep or slight relaxation are scaled somewhat lower. Alpha-frequencies cover waves from 8 to 12 Hz. The individual is just ready to get up or relaxes without getting asleep. At this phase the soul is open and ready to accept stimuli, which may influence its brainwaves and which may reach its subconsciousness.

Theta-frequencies

Theta-frequencies are measurable during deep relaxation and light sleep with active subconsciousness. Its measuring rate covers 3 to 8 Hz. A human being getting asleep produces waves at the lower point of the measuring scale, the upper limit of the scale is reached at deep relaxation periods. Theta-frequencies are considered as most qualified to mentally train human brainwaves.

Delta-frequencies

The slow-wave sleep can be measured as Delta-frequency. Delta-frequencies cover waves between 0,2 to 3 Hz. During this quite unconscious phase human brainwaves are nearly inaccessible.

Gamma-frequencies

Gamma-waves cover frequencies over 30 Hz. They can be measure during phases of extremely high concentration or intensive learning periods. Gamma-frequencies are invisible at EEG papers to the unaided eye.

Depending on the frequency of brainwave music you can promote or influence relaxation, learning abilities, concentration or various emotions or feelings. The best phases to influence a person are Alpha- and Theta-frequencies, which cover transition periods. Someone creating brainwaves at these levels is in some way caught in the middle of two worlds: the outerworld and his interior. During transition phases humans are able at their best to link the subconscious with stimulus of the outerworld. This is the point brainwave music starts: with its special techniques it can train and influence brainwaves.
