Transcript
Your brain is made up of billions of brain cells called
neurons, which use electricity to communicate with
each other. The combination of millions of neurons
sending signals at once produces an enormous amount
of electrical activity in the brain, which can be detected
using sensitive medical equipment (such as an EEG),
measuring electricity levels over areas of the scalp. The
combination of electrical activity of the brain is
commonly called a Brainwave pattern, because of its
cyclic, 'wave-like' nature. Our mind regulates its
activities by means of electric waves which are
registered in the brain, emiting tiny electrochemical
impulses of varied frequencies, which can be
registered by an electroencephalogram.


1 Beta emited when we are consciously alert, or we feel
agitated, tense, afraid, with frequencies ranging from 13 to
60 pulses per second in the Hertz scale.
Wide awake. This is generally the mental state most people
are in during the day and most of their waking lives.
Usually, this state in itself is uneventful, but don't
underestimate its importance. Many people lack sufficient
Beta activity, which can cause mental or emotional disorders
such as depression, ADD and insomnia. Stimulating Beta
activity can improve emotional stability, energy levels,
attentiveness and concentration.



2 Alpha when we are in a state of physical and mental
relaxation, although aware of what is happening
around us, its frequency are around 7 to 13 pulses per
second.
Awake but relaxed and not processing much
information. When you get up in the morning and just
before sleep, you are naturally in this state. When you
close your eyes your brain automatically starts
producing more Alpha waves.
Alpha is usually the goal of experienced meditators,
but to enter it using NP2 is incredibly easy. Since
Alpha is a very receptive, absorbent mental state, you
can also use it for effective self-hypnosis, mental reprogramming, accelerated learning and more.


3 Theta more or less 4 to 7 pulses, it is a
state of somnolence with reduced
consciousness.
Theta can also be used for hypnosis,
accelerated learning and selfprogramming using pre-recorded
suggestions, just as you are falling asleep.


4 Delta when there is unconsciousness, deep
sleep or catalepsy, emitting between 0.1 and 4
cycles per second.
Deep, dreamless sleep. Delta is the slowest
band of brainwaves. When your dominant
brainwave is Delta, your body is healing itself
and "resetting" its internal clocks. You do not
dream in this state and are completely
unconscious.


Rapid Eye Movement- stage of sleep in
which the brainwave activity is at the
Beta stage, but the person is completely
asleep.
Stage of Sleep in which dreaming occurs

In a normal night's sleep, a sleeper begins in
stage 1, moves down through the stages, to
stage 4, then back up through the stages, with
the exception that stage 1 is replaced by REM,
then the sleeper goes back down through the
stages again. One cycle, from stage 1 to REM
takes approximately ninety minutes. This cycle
is repeated throughout the night, with the
length of REM periods increasing, and the
length of delta sleep decreasing, until during
the last few cycles there is no delta sleep at all.
