Understand brain waves and master you life

UNDERSTANDING BRAIN WAVES
The brain has an electrical activity which in the different areas of the
brain made up of neurons, the nerve impulse works in relative
coherence and rhythmically.
Neural cells activate together (more or less), like a heartbeat, then
calm down, then activate again.
Many serious scientific studies have been carried out to determine
the frequency range and the mental states and behaviors associated
with it. These studies have produced incredible results that link the
metaphysical abilities and actual frequencies of the brain.
The methods used to measure brain waves are:
electroencephalogram (EEG), skin receptivity and temperature,
heartbeat, muscle tension, attention tests, effects on immunity (tests
blood ...).
Brain waves (brain activity) are divided into 5 main categories (Delta,
Theta, Alpha, Beta and Gamma), depending on the frequency of the
waves emitted or their number of oscillations per second of these
waves in hertz (Hz). One hertz equals one ripple per second.
The human brain emits waves 4 to 45 oscillations per second. These
brain waves measure between 10 and 100 Megameter
(1 Mm = 1,000,000 meters = 1,000 km).
These brain waves have a very low amplitude, a very short frequency
(a few hertz), and a low power (a few microvolts).

THE FIVE MAIN BRAIN WAVES IN DETAIL
1. Delta brain waves or rhythm
Delta waves are the slowest of all 5 brain wave frequencies.
Location: temporal lobes and in subjective states on the occipital
lobes.
They are between 0.1 and 4 Hz. Lower and its brain death...
Delta waves are obtained in a state of slow sleep; they manifest
themselves during deep sleep with rapid eye movements.

Delta waves are involved in our capacity to integrate and let go; it is
an unconscious state and deep sleep. They reflect the unconscious
mind.
This is the dominant rhythm of young children from around 3 months
to 1 year old. It tends to be the highest in amplitude for the slower
waves.
We are increasing our Delta waves in order to decrease our
awareness of the physical world.
This is when cell divisions and the production of growth hormone
take place, hence the importance of sleep in children. The more the
frequency drops below 4 cycles per second, the more we sink into
states of inertia.
Before dying, Delta brain waves are the last waves we make.
From a spiritual point of view, the Delta cerebral rhythm opens an
access to “God”, to an “infinite intelligence” or even to a “collective
unconscious”.
Characteristics: bilateral subjective states, deep sleep, lucid
dreaming, trance, associated unconscious tasks, lethargy, immobility,
states of deep relaxation. Immune defenses, healing, mental and
physical recovery, disappearance of migraines and headaches, near-
death experience, hyperconsciousness...
2. Theta brain waves or rhythm

Theta waves have a fairly low frequency of 4 to 8 Hertz and are
related to creativity, intuition and reverie. It is a deposit for memory,
emotions and sensations. This is also the phase of slow sleep (falling
asleep). The Theta rhythm reflects the activity of the limbic system
and the hippocampus region. This rhythm is observed in anxiety,
activation and inhibition of behavior.
It is a state of deep relaxation, fully awakened, achieved in particular
by people trained in meditation. It is a state used in hypnosis. It
reflects the state between wholeness and sleep, and it is also a state
that some people access through deep meditation and prayer.
Theta waves are connected to our subconscious; they govern the
part of the mind between the conscious and the unconscious. They
contain memories and sensations.
The Theta rhythm allows us to access the subconscious. They also
govern our attitudes, beliefs and behaviors. These waves are related
to the states of super inspirational creativity and spiritual awareness.
Between birth and the age of 7, children mainly operate at low Delta
and Theta frequencies. This is why children can acquire such a
large volume of information. They carefully observe what is going on
in their environment and adopt the behavior and beliefs of those
around them. We use these Theta brain waves when we engrave in
us oaths, promises with ourselves. We return to that same Theta
state to abolish these oaths.
The Theta state allows us to immediately eliminate and replace
particular thought patterns on all levels where they are recorded in
the body: freeing us from these patterns, freeing our energy and free
will. Only a few basic schemas support thousands of related beliefs.
In this Theta wave state, there is no separation, we usually lose track
of time. The slower this rhythm, the more deeply asleep the subject
becomes.

This state is one of the most elusive and extraordinary realms you
can explore. It is also known as the twilight state that you experience
only fleetingly upon waking up, or dozing off to sleep.
In this Theta wave state, there is no separation, we usually lose track
of time and feel one with the whole Universe. According to Maxwell
Cade, researcher and creator of the famous Mind Mirror device, there
is a state in which the Theta rhythm is continuous and the Alpha
rhythm tends to approach the Theta rhythm. This would occur in
states of lucid consciousness, as Maxwell Cade observed in healers
and mystics who participated in his research.
3. Alpha brain wave or rhythm
The Alpha rhythm is broken down into 4 levels
.
Level 4, very close to the waking state, is activated automatically as
soon as one takes a relaxed position, either comfortably installed in
an armchair, or lying on a bed, and that the we close our eyes.
At this moment, our brain automatically slows down the cerebral
waves, then if we persist longer, we then feel our whole body relax,
relax, this is level 3 of the alpha rhythm.
At level 3, our mind is still very active. We are still able to think of ten
thousand things that worry us ... then comes the moment when we

have the feeling of high, to be well. At this point we would be almost
unable to know what we were thinking, this is level 2.
Then just after this phase, we sink a little further, we go through level
1, the basic level of the Alpha rhythm. Without even realizing it and
because we are not aware of it, we fall even lower in sleep and there
our brain is already functioning in Theta ... and it's a shame because
just before that, the opportunity was ours given at level 1, the basic
level of Alpha rhythm, to open the door to our subconscious
and give it specific orders so that it serves us instead of serving
us, as it often does...
These waves (alpha waves) were the first signals identified by Hans
Berger, the inventor of EEG (electroencephalography) because of
their large amplitude. Alpha waves have a frequency ranging from 8
to 12 hertz and 30 to 50 microvolts in amplitude.
These are the frequencies most present in the total activity of the
brain (the brain emits several frequencies at the same time, at
different amplitudes). The frequencies of the Alpha rhythm are very
close to the frequencies that the earth produces and which are called
resonances of Schumann (7.83 hertz). Shamans have used
techniques to tune into the earth's telluric energy since ancient times.
It is possible that these techniques were intended to get the
shaman's brain to harmonize with the frequency of the earth.
The Alpha state is when meditation begins and you will begin to
access the wealth and creativity that is in your subconscious. It is the
gateway to deeper states of consciousness.
Alpha waves disappear when the eyes are open. As soon as we
have our eyes closed, when we rest, the encephalogram shows a
slowing down of our brain waves. This stage close to relaxation is a
stage of transition between awakening and the sleep. The subject is
then dozed off, but remains very sensitive to external stimuli. It is the
main rhythm of relaxation in adults.

Alpha waves are a bridge between conscious and subconscious.
Alpha rhythms are reported to be derived from white matter in the
brain. White matter is the matter of the brain that connects all the
pieces to each other.
The formation of Alpha and Theta waves can create sensory
intensification, abstract thinking and composure.
This frequency is related to extraversion, creativity, and mental work.
When this rhythm is within the normal ranges, we are calm and we
have a clear view of the world. We increase the Alpha frequency by
closing our eyes or breathing deeply and we decrease it by thought
or calculation. Nature has predicted that when we are at the
awakening level, that is, we are functioning at the Beta rhythm, our
brain drops very regularly in alpha waves, without us being really
aware of it, and this to avoid “overheating” our brain. Almost 30 times
per minute, our brain cycle drops only a few microseconds to the
rhythm of Alpha waves.
When we operate at the Alpha Brain Rhythm, the two hemispheres of
our brain work in perfect harmony.
This allows us, among other things:
- To have a more global vision of things, better concentration and
better memory.
– To be able to better manage our states of stress and our emotional
states.
- To take conscious control of the functioning of our body, to our
organs, and our physiological reactions.
- To be able to take control of our habits, especially those we want to
change.
At the Alpha level, we have a better perception of all our senses; we
are much more attentive to our intuition, which means that we know
what to do when it is necessary to do it.

Our mind is then “on the back burner”, it interferes less often and our
choice is then more correct, more intuitive. Intuition can be defined as
this faculty of knowing information which is outside our usual field of
perception.
4. Beta brain waves or rhythm
Beta brain waves can be separated into 3 subcategories:
• The first corresponds to the highest beta waves ranging from 19 to
34 Hertz. When these waves are the dominant ones in brain activity,
anxiety and stress are likely to occur.
• The second sub-category with frequencies ranging from 15 to 18
Hertz. They are characterized by action.
• The third is Beta SMR (Sensorimotor Rhythm) activity ranging from
13 to 15 Hertz.
Although in this state the emphasis is also on interaction with the
outside environment, the person is more relaxed than in the state
associated with the previous Beta.
The 14 Hertz frequency has gained the attention of researchers and
clinicians using EEG neurofeedback instrumentation. The real benefit
of creating a brain frequency of 14 Hertz in humans has not yet been
proven, but a study from the University of California, Los Angeles

found that felines can produce 14 Hertz at will, while cats can
produce 14 Hertz at will. Humans cannot. From there to thinking that
their alert capacity is associated, there is only one step...
Beta waves correspond to oscillations of frequency from 12 to 45 Hz
but of low amplitude (from 10 to 30 µV). They are captured on the
temporal lobes and in subjective states on the occipital and frontal
lobes of the brain state of an attentive subject with open eyes.
Brain waves switch to Beta during short periods of dream-sleep
(REM sleep), as if the dreaming activities were “routine” activities.
The Beta cycle is the awakening cycle that punctuates our brain
when we are with our eyes open in action: therefore we listen and
think during analytical problem solving, judgments, decision making,
and processing of related information to the world around us. Our
brain is then working at full speed.
Associated behaviors: focused, integrated tasks and behaviors.

Physiological correlations: an increasing rhythm improves
attention spans.
Subjective states: thought, the informed state.
Physiological correlations of mental activity: alert effects, active,
but not agitated, can increase mental abilities, alertness, high IQ in
beta waves (above 18 hertz).
Median Beta Rate: subjective states of feeling, alertness,
restlessness.
Behavioral states: mental activity, mathematics, planning...
Physiological correlations: general activation of mind and body
functions.
5. Gamma brain waves or rhythm
Gamma waves have a frequency of approximately 35Hz to 80Hz,
which is the only group of frequencies present in every part of the
brain.
When the brain must simultaneously process information from
different areas, activating a frequency of 40Hz promotes information
between the areas required for simultaneous processing. Good
memory is associated with 40Hz activity, while insufficient 40Hz
waves create study disabilities.
Subjective states: thought, high mental activity including perception
and consciousness. The senses, the intellect, the intuition, or even

the memory are put to work harmoniously and synchronously. The
emission of this type of waves, with rapid oscillations, would
reflect in a way the full consciousness through the being.
Behavioral states: integration of thoughts, Physiological correlations
“binding” correlations, processing of complex tasks.
Controversy is still strong as to whether these are specific waves or a
form of Beta rhythm.
Gamma waves are, however, found in states referred to as active
consciousness, such as attentive cognitive processing (for example,
concentrating on a problem) or attentive perception (for example,
analysis or recognition of a smell). The amplitude of the Gamma
waves, higher than the Beta rhythm, could testify to a synchronization
of consequent neuronal groups, coherent with the idea of an
increased consciousness or a targeted cognitive processing.
SUB-CATEGORIES OF BRAIN WAVES
1. Epsilon brain waves or rhythm> 0.5 Hz
Consciousness researcher Dr Jeffrey Thompson has modified
conventional EEG equipment to study the extraordinary states of
consciousness of meditators and seasoned yogis. He later decided to
call up one of these unusual states of consciousness. He discovered
Epsilon waves, an even slower brain wave pattern than Delta.
Mr. Thompson found that the range for this pattern was from less
than 0.5 Hz (or cycles per second) to a quarter cycle every ten
seconds. He also discovered the properties of this model which led

him to believe that it was a carrier wave for the ultra-fast brain wave
patterns he had observed in other meditation experts, at times
speeds as fast as 200 Hz or more.
When we talk about brain wave states, the delta frequency, which
has long been the slowest frequency on record, is normally
associated with deep, dreamless sleep. Below, less than one cycle
per second, we enter the range called Epsilon, which can be as slow
as a wave measured every 10 seconds or so. They are very slow
waves. Epsilon is associated with people who enter a kind of
"stillness" state. It's not a near-death experience, but it does involve
slowing his heart rate to its lowest point, as well as decreasing his
brain wave frequency as much as possible. At the bottom, at the very
low end of 0.5Hz or less, you start to enter Epsilon. Then the Lambda
waves emerge in parallel.
2. Alpha Brain waves or Mu rhythm: 8 to 12 Hz
Brain-computer interfaces (BCI) are currently the subject of several
approaches by various researchers around the world. One approach
is to measure "Mu rhythms" or also called "Mu waves" from the
sensorimotor area of the brain by recording an EEG signal. Mu
waves are associated with movement of the body - either by actually
moving a part of your body or by “thinking” about the possibility of
moving that particular part of your body. Since they only appear when
the body is completely relaxed, Mu rhythms have a specific range of
high activity at a frequency of about 8 to 12 Hz. In addition, it is
believed that this activity is produced by interactions between the
thalamus and the cortex.
Mu rhythm occurs in the frequency range commonly referred to as
Alpha waves (8 to 12 Hz). There are several sources of activity in the
Alpha range. When you close your eyes, Alpha activity immediately

increases. Usually, if you close your eyes, the visual cortex is
activated, causing alpha waves to appear all over the back of the
brain. This type of activity is known as posterior dominant rhythm
(PDR). In contrast, Mu waves are associated with the sensorimotor
area of your brain. They should therefore only appear in the EEG
signals from the electrodes located above this part of the brain.
How can we measure Mu waves?
Theoretically, if you hook up an EEG sensor system to your scalp
and select very specific electrodes located in the narrow
sensorimotor sensor in your brain, you should be able to identify the
Mu waves on the screen when your body is physically active and
relaxed. In practice, there is a tutorial from the BCI2000 wiki which
helps to get a better idea of the most accurate electrodes to record
Mu activity, where to locate the reference and ground electrodes.
3. SMR waves (Sensory Motor Rhythm): 12 to 15 Hz
There is a frequency band between the beta and alpha values, called
the SMR rhythm (13 to 15 Hz), the amplitude of which increases with
immobility and decreases with motor activity or visualization of
movement. SMR is linked to alertness and helps regulate impulsivity
and hyperactivity, generate body awareness, and control anxiety and
anger. Thus, training in these frequency bands could help with
autism, epilepsy, and severe learning disabilities.
• The brain's sensory and motor bands control the sending and
receiving of movement messages, intended for your arms, legs,
shoulders, hands, feet and other parts of your body.
• SMR is involved in inhibiting movement during sleep, which is why
low levels are linked to insomnia.

• Regular exercise and physical activity are known to increase SMR
levels over the long term.
• Athletes, dancers, swimmers, and generally active people tend to
have high levels of SMR activity in the brain.
• ADD / ADHD – AB (Attention Deficit Disorder/ Attention Deficit
Hyperactivity Disorder) is good for concentration. It is often found that
people with ADD / ADHD have very low levels of SMR waves.
Also good for depression and anxiety
If you are depressed you are likely to be producing a large amount of
slow wave, low frequency brain waves. It can be helpful to stimulate
your brain with higher frequency isochronous sounds and raise the
frequency of dominant brain waves to a higher level. One downside if
you climb too high is that it could elicit feelings of anxiety, which can
often be linked and associated with certain types of depression.
The benefit of boosting the 12-15Hz SMR range is that it's a good
mid-frequency range that will help you balance yourself out. If you
are feeling anxious, your dominant brain wave frequency will
probably be quite high; it will therefore be useful for you to guide you
towards the range of SMR waves. MRS is expected to provide relief
for people with anxiety and depression.
The meaning of SMR is not fully understood. Phenomenologically, a
person produces stronger amplitude of SMR when the corresponding
sensorimotor areas are inactive, for example during states of
immobility. The SMR generally decreases in amplitude when the
corresponding sensory or motor areas are activated, for example
during motor tasks and even during motor imagery.
Conceptually, SMR is sometimes mixed with alpha waves of occipital
origin, the most important source of neural signals in the EEG. One
reason could be that without proper spatial filtering, the SMR is very
difficult to detect because it is usually inundated with the strongest

occipital alpha waves. The feline SMR has been noted to be
analogous to the human mu rhythm.
4. Lambda brain waves or rhythm: 100 Hz - 200 Hz
Lambda brain waves are one of the least known frequencies and the
last to be discovered. They are rare and difficult to measure. This is a
very fast brain wave frequency, even above the hyper-gamma
spectrum. With a lambda wave, we are talking about 200 Hz.
The state of consciousness caused by Lambda waves is more like a
slow, deep wave. Most of what you get from meditating with a
lambda workout is a lot like what you get with a very deep epsilon
rate, but without the drowsiness.
