Human
brain normally
operates within a
range
from 1 to about 40 Hz. ( 0.16 Hz to 35 Hz in -6 dB : standard EEG
amplifier filter specification )
for
the purpose of EEG
(electroencephalogram)
analysis and clinical description, the frequency band has been divided
into a number of so-called rhythm.
Richard
Caton of England showed as early
as 1875 that waves of electrical activity can be record from the
surface
of the brains of animals, but this finding lay unnoticed until the work
of Hans Berger, of Germany, in the 1920s.
Berger
was a psychiatrist,
and
also served as Rector of the University of Jena.
His
main research
interest
was determining what he called the physical basis of psychic function.
Berger's
report in 1929 that electrical waves could be recorded from
the
scalp, subject was his young son.
These
early studies established that
the dominant rhythm in the resting subject is 8-13 Hz, and is most
prominent
when the recording leads are over the occipital lobe of the brain
(where
the primary visual cortex is located).
This
is called Berger rhythms,
now
called it Alpha rhythm.
The
human
brain is
estimated to be able
to store information in the quantity between 1 X 10 ^11 (one hundred
trillion)
and 2.8 X 10 ^20 (280 quintillion) bits of information, by about 10
trillion
neurons.
Those neurons information network makes electric current flow
in the cortex where synchronous interactions yield oscillations in the
frequency band from 1 Hz to 40 Hz.
these frequency oscillations a
similar
to the geo-electrical Schulman Waves generated in the ionosphere, to
which
all organism have been exposed throughout their period of evolution.
The
resonant frequency
of the earth
ionosphere
cavity is about 7.5 Hz and the micro-motion of the body is from 6.8 to
7.5 Hz.
This suggests a tuned resonant system. In deep meditation, a
human
being and the planet starts resonating and transferring energy at the
very
long wavelength of 40,000 km, the perimeter of the planet Nature finds
it more economical in terms of energy to have periodic events that are
close enough in frequency to occur in phase or in step with each other.
On
the
left is the
golden series and on
the right the average orbital periods of the planets of the
solarsystem.
Phi to the minus 3 power = .236 Mercury's
period = .24085 Tropical earth years
Phi to the minus 1 power =
0.6i8
Venus's period = 0.61521 Tropical earth years
Phi to the zero power =
1.000
Earth' s period = 1.00004 Tropical earth years
Phi to the 1 power =
1.618
Mars' period = 1.88089 Tropical earth years
Phi to the 5 power =
11.090
Jupiter's period = 11.86223 Tropical earth years
Phi to the 7 power =
29.034
Saturn's period = 29.4577 Tropical earth years
Consciousness
can only
be comprehended
if
you see it in terms of the environment in which it is embedded.
The
ratio of the orbital period of Mars to that of Mercury comes out to 7.8
which is almost exactlythe Schumann resonance fundamental of 7.83
cycles
per second.
Theinner coherence bands of electro encephalic
activity
(EEG) has theirouter doppelganger in the coherence bands of the
earth-ionospherewave-guide;
the so-called Schumann resonances.
The Schumann resonances as standing waves of potential created by thenatural radio wave transmitters called lightning bolts are not muchdifferent from the micro voltage pulses of potential measured fromhuman skull called EEG or the micro voltage pulses from the heartcalled EKG. The Schumann fundamental marks the boundary betweenconscious and subconscious selves.
Simply put, when EEG activity goes below 7.83 cycles per second peoplefall asleep or go into trance. If EEG activity goes above 7.83 cyclesper second they wake up or come out of trance. To put it yet anotherway the Schumann fundamental marks the point where attention switchesfrom external awareness to internal awareness.
The
fundamental
resonant frequency of
the
earth-ionosphere wave-guideis the fundamental resonant frequency of the
human brain's EEGactivity!
The
frequencies are
clumped into
categories
that denote their characteristics.
A Hz (hertz) is the number of cycles per second; the higher the
hertz, the faster the brain wave.
Delta
rhythm range from
1 Hz to 4 Hz.
During deep sleep, anesthesia, and are also present during
various
meditative states involving will ful conscious focus of attention in
the
absence of other sensory stimuli and some comas.
Theta
rhythm range from
4 Hz to 8 Hz.
It's called the hypnogogic state and is a kind of consciousness
twilight that occurs between being deeply relaxed and sleeping.
they appear to be prominent in the EEGs of normal children.
Alpha
rhythm range from
8 Hz to 12 Hz.
The normal basic rhythm for a
relaxed person with the eyes
closed.
the majority of normal adults can produce the Alpha rhythm, which is a
relaxed but awake state.
Beta
rhythm range from
12 Hz to 30Hz.
(Low
Beta: 12..15Hz (SMR), Mid Beta: 16Hz..22Hz, High Beta: 23..30Hz)
Which is the range of normal waking consciousness.
Sterman named the frequency sensorimotor rhythm a rhythmic signal
peaking in the range of 12 to 15 Hz that from a specific part of the
brain,
the sensorimotor cortex, and so it is called SMR.
The amplitude of the beta waves is
generally less than 20 micro
V.
Increasing the energy while lengthening the wavelength of the
brain wavers can act as both a magnifying lens and an amplifier, which
causes a narrowing of focus on beta waves. Narrow frequency band of
continuously
Beta peaks mean more focussing than wide frequency band of Beta peaks.
High amplitude mean more high focussing.
Coherence
To see brain wave phase synchrony between left and right brain
hemispheres. 1.0 mean 100% and 0 degree phase difference. 0.0 mean 0%
and
90 degree phase difference.
A shift in brain frequency involving the presence of EEG synch
between hemispheres precedes or accompanies non ordinary states of
consciousness
associated with meditation or trance channeling experience. when an
individual
shifts focus of attention, the entire frequency pattern of the brain
shifts
to different frequencies. This shift is of interest when it involves
synch
between hemispheres. The abilities to focus attention and to achieve
flashes
of insight have been created with increased phase synchrony between
hemispheres.
Relative
coherence
Calibrate coherence in amplitude relatively over time. This
process
eliminate left & right difference of sampling, electrode and skin
conducting,
brain tissue, etc.

Stage 1 : 3 to 7 Hz, Theta waves
Stage 2 : 12 to 14 Hz, Sleep Spindles and K Complexes

High voltage, Delta waves
Left
and Right brain
hemispheres
The first evidence that the hemispheres are different came from
the French neurologist Paul Broca. In 1863, his words "We speak with
left
hemisphere" based on his patient with the inability to speak (aphasia)
who turned out to have a tumor in the left frontal lobe. This work thus
clearly established that the left hemisphere is "dominant" for a
specific
function, speech.
Until the 1950s, this stood as an isolated exception to what
appeared to be the general equivalence of the two hemispheres in all
their
other function, sensory and motor.
Sperry the Nobel Prize in 1981, led to our present concept of
the laterality of higher functions in the human brain.
The left hemisphere is dominant for control of speech, language,
complex voluntary movement, reading, writing, and arithmetic
calculations.
The right hemisphere is specialized for mainly nonlinguistic
functions: complex pattern recognition vision, audition, and the
tactile
senses; the sense of space, spatial shapes, and direction in space; the
sense of intuition.
Personality
and the
Frontal Lobed
The role of the frontal lobe in reading out internal
representation
of stored information is only part of a larger role involving, in
humans, the entire personality of an individual. Currently, there is
considerable
interest in the roles of specific neurotransmitters and
neuromodulators,
especially dopamine. A variety of neuropharmacological manipulations
have
documented the antipsychotic effects of neuroleptic drugs on
dopaminergic
systems, including the prefrontal cortex. These studies support the
belief
that psychotic behavior is due to malfunctioning of specific brain
circuits,
and the hope that normal function can be restored by drugs acting on
the
synapses of these circuits.
