A secret swap for activating the hidden power of your mind
Discovering Brainwaves
The electrical exercise emanating from the brain creates frequencies called brainwaves.
Brainwave frequencies are measured in Hertz (Hz), meaning cycles for every next. The more cycles for every next, the greater the Hertz value.
There are four major categories of brainwaves ranging from the most exercise to the the very least exercise. These are: BETA, ALPHA, THETA and DELTA.
Each image below depicts a one next snapshot of human brainwave exercise, as detected by an electroencephalogram (EEG). As you'll notice, greater values indicate more brainwave exercise within the one next time-frame.
BETA BRAINWAVES are characteristic of an engaged mind, which is highly alert and well focused.
Beta exercise is quick-connect, fast exercise and tends to dominate the normal waking point out of consciousness when-attention is directed towards the outside world.
Typically detected in the frontal lobes (where decisions are managed), Beta is usually seen on both sides of the brain in geometric distribution. It may be absent or reduced in areas of brain damage. It is generally regarded as a normal rhythm and tends to be the dominant rhythm in those who are alert, anxious or have their eyes open.
Beta brainwaves are engaged when the brain is aroused or processing activities, such as:
involved conversations with others that command your full attention
complex problem resolving and assessment of situations
general public speaking, lectures or teaching information
ALPHA BRAINWAVES are slower than beta and can represent a relaxed recognition in the mind.
This rhythm is seen when the brain sets alone to rest or replicate. Alpha rates are increased by closing the eyes and relaxing, yet are offset by opening one's eyes or any concentrated effort.
Alpha is usually best detected in the frontal locations of the head, on each facet of the brain. Alpha is the major rhythm seen in normal relaxed adults and is typically regarded as the common relaxation manner beyond the age of 13.
Alpha brainwaves move towards deep relaxation, creativity and intuitive thinking, as they accompany:
a relaxed mind after complex thinking into a manner of relaxation
meditation and setting the mind's attention to alone, away from outside distractions
recovery from stressful thoughts and emotional despair
THETA BRAINWAVES can indicate drowsiness, daydreaming, the first stage of sleep or 'indirect' creativity/thinking.
Theta exercise is not often seen in awake adults (unless engaged in a meditative practice), but is perfectly normal in alert children up to 13 years and in most sleep.
A Theta point out can be regarded as a gateway to hypnagogic states that lay between being awake and falling asleep. Often Theta entrainment can promote vivid flashes of mental imagery as one becomes receptive to brain/mind information beyond one’s typical conscious recognition. Theta has also been identified as a part of learning, memory and reductions in stress.
Theta brainwaves are often related to:
accessing subconscious information that eludes the conscious mind
hynagogic states like 'daydreaming'
reductions in body rhythms, such as: heart rate and respiratory.
DELTA BRAINWAVES can reveal deep sleep or gradual-wave 'background' thinking.
Much like bass seem, Delta tends to be the highest in amplitude and the slowest waves. Delta is often associated with deep sleep. Certain frequencies, in the delta range, have been shown to trigger the body's healing and growth mechanisms.
Apparently, Delta is the dominant rhythm in infants up to one year, as well as levels 3 and 4 of dreamless sleep.
Delta brainwaves are often related to and indicate:
the lowest brain frequencies, possibly indicating subconscious thoughts and information
deep and refreshing sleep that allows the body and brain to rest and repair.
extremely deep meditation and hyper-relaxed mind states
It is important to note that the brain does not operate on one frequency range at any given time.
All four rates occur at once, yet at different amplitudes. A good analogy would be to relate each brainwave point out to a sting on a violin. All four strings make notes, yet one or more strings can dominate the overall seem at a greater volume.
The design of the Brain Evolution System lends alone to driving multiple rates at once, allowing you to entrain to a broad range of brainwave rates within each level.
