Often when people ask, "What are Alpha Brain Waves?",
they are really asking, "What are Alpha Brain Waves good for?",
and "What do Alpha Brain Waves mean to me?"
Answering the first question leads into the other two.

Alpha Brain Waves are one of
four basic brain waves
[Delta Waves, Theta
Waves, Alpha Waves, and Beta Waves] which make up the EEG,
which is short for electroencephalogram and also electroencephalograph.
The electroencephalograph is the recording device that produces
the electroencephalogram. These 4 brain waves are all oscillating
electrical voltages in the brain, but they are very tiny voltages, just a few
millionths of a volt. The Alpha brain waves oscillate about 10 times per
second, and the range is 8-13 cycles per second. The brain waves
called "Alpha" were the first to be discovered (around
1908, by an Austrian Psychiatrist named Hans Berger). That is why
they are called "Alpha waves",
Alpha brain waves were
discovered first. Alpha is the first letter of the Greek alphabet, like
our "a". Many hundreds of scientists have spent a lot of time
studying these basic brain waves of the EEG, so there is a lot of basic
knowledge about
what Alpha brain waves are and what makes them appear
and disappear in our brains. Yes, they appear and disappear. Alpha brain
waves are not always present. For example, in deep sleep there are no Alpha
brain waves, and if someone is very highly aroused as in fear or anger,
again there are virtually no Alpha brain waves. Delta brain waves are
seen only in the deepest stages of sleep (Stages 3 and 4). Theta
brain waves are seen in light sleep and drowsiness (sleep
stages 1 and 2). Alpha brain waves are seen in wakefulness where there
is a relaxed and effortless alertness. Beta brain waves are seen
in highly stressful situations, and where there is difficult mental
concentration and focus. Delta waves are the slowest oscillating brain
waves (0-4 cycles per second). Theta waves oscillate somewhat
faster (4-7 cycles per second). Alpha waves oscillate 8-13 times per
second. Beta waves oscillate still faster (13-40 cycles per second).
There are many other kinds of electrical activity in the brain, especially the
short-lived evoked potentials that occur when the brain responds to sensory
input (like a sound, or a touch, or a flash of light). However, the four basic
EEG brain waves; Delta waves, Theta waves, Alpha waves,
and Beta waves constitute the standard lineup of EEG brainwave activity.
What are Alpha Brain Waves Good For?
The foregoing discussion makes the point that each of the
four basic EEG brain waves is linked to a different state of
consciousness. Each of the four types of brain waves (Beta, Alpha,
Theta, Delta) is good for something different. However, we can get into
trouble if we can not turn on the type of brain wave needed for the task at
hand. For example, if we can not turn on Theta brain waves and Delta
brain waves, we will suffer from insomnia, among other things. On the other
hand, people who can turn on the ideal brain waves to deal with
each and every situation are considered gifted.
One useful metaphor compares the four basic brain waves
(Delta, Theta, Alpha, Beta) with the four gears on a car. Delta brain waves
(the slowest waves) are first gear. Theta brain waves are second
gear. Alpha brain waves are third gear. Beta brain waves are fourth
gear. No one gear is best for every driving situation, and no one brain wave is best for all of the
challenges of life. We get into trouble if one of the gears on our car goes
out, or if we forget to use some of the gears. For example if we drive our car starting
in first gear, and then shifting directly into fourth gear (skipping second and third), we will have low gas mileage and high repair
bills. The same is true of our brains. Sadly, many people often skip their second and third
brain gears (Theta and Alpha brain waves). The
consequences of driving our brains in this manner are low productivity and high
medical bills. How does this happen?
The way this occurs in everyday life can be illustrated
by an example. People often wake up suddenly out of a deep sleep (Delta
brain waves) with an alarm. Then they immediately feel stress and anxiety (Beta brain waves)
about being late or being under time pressure. After insufficient sleep they pour
caffeine down their throats to force themselves into (Beta brain waves) wakefulness,
and the caffeine suppresses Theta and Alpha brain waves, while
promoting Beta brain waves. All day they work under stress, pressure, and time urgency (Beta, Beta, and
more Beta), until at night, they fall exhausted into deep sleep (Delta
brain waves), having spent too little time unwinding, relaxing, and drowsing (which would have given them a bit
more Theta and Alpha brain waves). Thus many people shift their
brains suddenly and forcefully from Delta to Beta, and then back to Delta.
Alpha brain wave production
is an innate skill of our brains, but one consequence of the modern stressful
lifestyle is that we forget how to produce Theta and Alpha brain
waves. Then we easily fall victim to anxiety and stress-related diseases.
Anxiety and stress measurably reduce the strength of our immune systems. People
who have more Alpha brain waves have less anxiety. Thus having more
Alpha waves could mean less anxiety and, correspondingly,
stronger immune systems, and this is good for everyone.
Creativity is
another activity for which Alpha brain waves are helpful. Scientists
have shown that highly creative people have different brain waves from
normal and non-creative people. In order to have a creative inspiration,
your brain needs to be able to generate a big burst of Alpha brain waves,
mostly on the left side of the brain. The brains of creative people can generate these
big Alpha brain wave bursts, and do so when they are faced with problems
to solve. Normal and non-creative people do not produce Alpha brainwave increases
when they are faced with problems, and so they can not come up with
creative ideas and solutions. Any time you have an insight or an inspiration,
you know your brain just produced more Alpha waves than usual. Increased creativity is helpful
for everyone. One way to increase creativity is to increase Alpha brain waves.
Peak performance is another activity for which Alpha brain waves are
helpful. Recently sports scientists have shown that increases of Alpha
brain waves (often in the left side of the brain) precede peak
performance. One key difference between novice and elite athletes is
in their brain waves. Just before their best free throws, an elite basketball
player will produce a burst of Alpha waves on the left side of their brain.
Just before their best strokes, elite golfers will produce a burst of Alpha
waves in their left brain. Just before their best shots, elite
marksmen and archers will produce a burst of Alpha waves in their left
brains. Novice and intermediate athletes do not show this Alpha brain wave pattern.
However, one study of archers training over many weeks, showed that as
they improved their performance, they gradually increased the amount of left
brain Alpha waves which occurred just before their best shots. The Alpha
brain waves seemed to be essential for peak performance and were
increased, albeit slowly, by the archery training.
What Do Alpha Brain Waves Mean to Me?
If you want to feel less stress and anxiety, you
should increase the amount of your Alpha brain waves. This may
also improve the strength of your immune systems, since stress weakens the immune systems. If you
want to be more creative, you should learn how to increase the amount of
your Alpha brain waves. If you want to have more peak
performance in athletic activity, and in other areas of your life, you
should learn how to increase the amount of your Alpha brain waves. Some
people are born healthy and mellow and gifted with creativity and
athletic prowess exemplified in peak performance. But what if you
are not so lucky?
Is there a method to increase your Alpha brain waves?
Yes, you can increase your
Alpha brain waves via brainwave biofeedback training using state of the art neurofeedback systems
provided by the Biocybernaut Institute during brain wave training.
