Brain
Wave States

What
are the main brain wave states.
Why is the alpha brainwave state
interesting for personal
development?
The
human brain, fabulous computer,
is made of millions of brain
cells. Every cell holds the
electric current. Many
researches are done in the area
of human brain. It seems that
many things are still to be
discovered. Still, what we
learned by now is giving us the
relation between electrical
activities in the brain and
brain function. Since the
activities of the brain are
showing electrical impulses. The
electrical activity of the brain
cells is creating the
brainwaves. The research of the
electrical activities and brain
waves is done with the use of
electroencephalograph ( EEG ).
The brain waves are grouped in
four main groups: alpha, beta,
theta and delta. Frequency of
waves caused by electrical
activity is measured in Hertz (
Hz ).
-
Delta
brain waves slowest range of
frequencies. They
oscillate between 0 and 4
Hz. Delta waves are
occurring during the deepest
sleep. Delta state is
present during coma state or
during the anesthesia.
-
Theta
brain waves ere related to
dreams, deep relaxation and
daydreaming. The frequency
of theta brain waves is
between 4 and 8 Hz.
-
Alpha
brain waves are associated
to brain state during
practicing a different
mental disciplines. The
meditation precisionists
were tested with EEG
equipment and it was shown
that their brains are tuned
to alpha state. Also the
meditation precisionists can
shift to theta brain state.
The alpha brain state is
taking the range between 8
and 14 Hz.
-
Beta
brain waves are associated
to wakefulness, reasoning,
analytical activity, problem
solving, etc. All emotional
states like stress, joy,
pain, fear or jealousy are
occurring when the brain in
the beta state. Beta
brainwaves are taking the
range above 14 Hz.

Now
we see that state of mind
greatly depends of brain
wave activity. Electrical
activity of the brain is
shaping the state of mind.
Without having a brain
tuned to the right
frequency it is impossible
to achieve desired mental
activity. If you want to
meditate, you need to have
lower your brain wave
frequency from wake beta
state to alpha. If you do
not lower your brain
frequency you will not be
able to meditate, since
your brain will be to
loud. If you lower the
brain state frequency too
much you will fall asleep.
On the other side, if you are driving you need to stay awake. But
if you are tired than your
brain is shutting down
gradually. You need to
wake it up with coffee and
stretching legs, or even
to park and take the nap
in order to rest your
brain.

Basically,
tuning the brain to the right
frequency is not easy, since it
is not directly under the
influence of the conscious will.
Brain wave state depends of many
things, like activity cycles,
sleeping habits, nutrition, etc.
On the other hand the tuning of
the brain is possible through
training. One of effective aids
for tuning the frequency of
brainwaves to desired frequency
are binaural beats programs that
entrain your brain with
specially designed audio
programs.
For
sure, the alpha brain wave state
is the most interesting to be
trained. Meditation, hypnosis or
learning are the processes where
you are in the brainwave state.
The alpha state is also
difficult to stay in since you
are on the thin edge of falling
to sleep or awaking. Maybe the
next step of your personal
introspective and development
can be training to tune into
alpha brain wave state.
