THE EFFECTS OF THE PRACTICE OF QIGONG ON THE EEG
Hu
I.inqi
and
others
recorded
ordinary EEG of
30 subjects practicing
relaxation Qigong and analyzed the power spectrum.
In the
first systematic
test before
the subjects
had
learned relaxation Qigong,
there were no clear
differences between
the duration
of power,
and prior
to power,
in
the various
frequency bands
of
the
EEG power
spectrum.
However,
after three months
of
Qigong training,
the
EEG
alpha
wave
band
occupied
a
markedly
increased
percentage
of
the
entire
power
spectrum.
The EEG power spectrum array
analysis
also showed
a gradual
increase
in
the
alpha wave
spectrum
energy.
The rise
in
the
EEG
wave
index
is acknowledged
as representative
of
the
degree of relaxation.
Therefore,
any type
of positive state
can
lead
to
an
abatement
of
the alpha
rhythm.
We can
see from the results
of analysis
of
the power spectrum
in
the
EEGs
in
this
experiment
that
the
alpha wave
proportion
of
the EEG power spectrum of
the group practicing Qigong showed
a
clear
increase during the course
of practicing Qigong compared
to what
it was
prior
to
practicing Qigong.
We
can detect
in the EEG power spectrum array
that during the
entire
15 minutes
of
Qigong
exercise
the
EEG
alpha wave
spectrum energy
increased.
This illustrates
that the
alpha wave
increase
actually reflects
the degree
to which
the cerebrum
enters rest
during the
exercise.
Furthermore,
the degree of entering rest gradually increases.
Zhang Jianzhou
and others conducted
an analysis
of statistical
charts
of
the electrical potential
in
the EEGs
of
the
Qigong functional
state.
The
EEGs
of
a
group
of
Qigong
masters
(a
total
of ten persons who
had
all
practiced Qigong for more
than
ten years)
taken
before the
Qigong exercises
and
eight
minutes
into
the
Qigong
exercises
when they were
in
a Qigong
functional state were compared.
A
single
line
can be
seen
on
the
T
test
isopotential
distribution
chart.
The cerebrum frontal hemisphere
alpha
x
component shows
the clearest
changes
(P
<
0.05.
From
the
isopotential
distribution
graph
of
another
related
factor
we
see
that
there was
a
weakening correlation
or
a negative correlation
of the
vast majority
of
the
EEG
components
In
order
to
explain the changes
in
the interrelationships
between
the various parts of the
brain
in
the EEG
after entering
a Qigong
state,
they
also conducted
analysis of correlated isopotential distribution
graphs.
The design was
to divide the cerebrum into
four sections,
the
left
front,
right
front,
left
rear
and
right
rear
and still emphasizing the
observation
of
the alpha
i_ rhythm.
The positive correlation between
the
left
and right
and
the
negative correlation
between
the
front and
rear can be
seen.
The control
group
(ten
healthy
individuals)
also
had
their EEGs
recorded
into
three bands.
This group closed their eyes and sat quietly for
five minutes and
then relaxed
(imitation
of Qigong)
for
ten minutes,
and then
sat
quietly
for
five
minutes.
On
the
EEG
change T test isopotential
distribution chart
of
this group we can see
that their
“degree
of greyness"
is
lowest.
This illustrates that there was no clear change
in their EEG from
the
time
they closed their eyes and
sat
quietly
to
the
time
they copied
Qigong.
Analysis
of the correlation
index of
their
isopotential distribution
chart shows that their
"degree
of
grayness"
was
highest,
indicating the
strongest positive
correlation,
there
was no antagonism.

There were active changes

actions

state.
We
discovered
that
as
the
testing time was extended
for normal persons,
it was
also possible
to
record occasional EEG changes which were similar
to those
of
the Qigong
functional state,
but these changes were
less
in degree,
followed
no pattern and
had no statistical
significance.
From another
aspect,
when
normal
people
go
through
Qigong
training,
they are completely capable
of
entering the same sort
of functional state
as
the Qigong
masters
and display
similar
changes
in
the
EEG
waves,
the
power spectrum
of
the EEG
in
the
functional state
is more
complex.
This
can
be due
to
the
fact
that
the
Qigong masters
practice different
types
of
Qigong,
and
the
locations from
which they transmit
the aura are different.
When
they
are transmitting the
aura,
they
manifest
an
overall power
increase
in the power spectrum
in
the
various
leads
and
these
are not synchronous.
This
is
the cortipal
inhibition
of the
Qigong master
from the
time
of entering relaxation,
skipping
to
the
cortical excitation process,
and switching from the synchronized
to
the non-
synchronized
b
wave EEG
waves.
This explains
the speeding up of
the
EEG
rhythm,
the cortical neuron activity,
and enhanced excitation
and tenseness.
During
the
process
of
the
Qigong
master entering relaxation,
he makes
a
series of adjustments
in entering the functional
state.
The
cerebral cortex
functions also go through two completely separate functional
states.
This
is
the nervous
mechanism of
the Qigong
master switching
from
a psychological
process
to
a
physiological
process.
The
conclusion
is that during the
process
of Qigong entering relaxation,
the
EEG power
spectrum shows changes
in Q
synchronization,
characterized by an
increase
in
the frontal
lobe alpha
wave power spectrum.
During the
functional state,
the EEG
power spectrum
tends
to be
b wave
form,
displaying desynchronized EEG waves,
and
an
increase
in
the power spectrum energy of all
leads.
Hong Zhi and others
used
a
computer
to
analyze
and
study
the EEG
characteristics
of
a
super
relaxed
state.
The thought activities
of the
human brain play the role
of
the
director
in
entering
the
super relaxed
state,
and
the frontal area
is
the area of
the brain most recently formed
in
the evolutionary process
of
the human brain.
The frontal
area
is
the place
where nervous processes become thought processes,
and
is
an
important area of
conscious activity.
Therefore , they
an EEG
signals analysis
of the frontal
area as
a beginning
to recognize
normal states
of relaxation and states
of
super relaxation,
and
found
common
characteristics
of
super relaxation.
There were eight people
in
the Qigong group,
all
of whom had practiced Qigong
for three years or more.
During
the
tests,
the
EEG
of
each
person was
recorded
for
minutes.
Five
minutes were prior
to Qigong,
30 minutes
during Qigong,
and
five
minutes
after
Qigong.
The
control
group were
requested
to
copy the
Qigong group
for
the
test.
The results were:
The
frontal area EEG
showed
marked
differences
between

relaxation
and
common relaxation.
During Qigong super relaxed state,
the EEG power spectrum
greatly increased,
with the spectrum peak frequency moving down.
The
largest
spectrum peak
location reached
4.7 Hz.
That
is
the transition from the pre

wave dominance
to

energy.
