The first, beta waves, (13-35 Hertz or pulses per second) are associated with normal activity. The high end of this range is associated with stress or agitated states that can impair thinking and reasoning skills.
The second group, alpha waves (8-12 Hertz), can indicate more relaxation. Alpha frequencies are ideal for learning and focused life form energy.
The third, theta waves (4-7 Hertz), indicate mental imagery, access to memories and internal mental focus.
This state is often associated with young children, behavioral modification and sleep/dream states. The last, ultra slow, delta waves (.5-3 Hertz), are found when a person is in deep sleep.
The general rule is that the brain’s predominant wave frequency will be lowest, in terms of pulses per second, when relaxed, and highest when people are most alert or agitated.
External stimulation of the brain by electromagnetic means can cause the brain to be entrained or locked into phase with an external signal generator.
Predominant brain waves can be driven or pushed into new frequency patterns by external stimulation.
In other words, the external signal driver or impulse generator entrains the brain, overriding the normal frequencies, and causing changes in the brain waves.
Changes in brain waves cause changes in brain chemistry; which then cause changes in brain outputs in the form of thoughts, emotions or physical condition...<<<Read The Full Article Here>>>...
