Abstract
The study of reactions of human CHS to peripheral effects of
EHF
emission,
created
by
therapeutic
apparatus
Yav-I
(the
wave
length
is
7.1
mm)
revealed
restructuring
of
the
space-time
organization
of
biopotentials
of
the
brain
cortex
of
a
healthy
individual which indicate development of a non-specific activation
reaction
in
the
cortex.
The
study
of
sensory indication of
EHF
field
with
these
parameters
showed
that
it
is
can
be
reliably
detected at the sensory level by 80% of the subjects.
Tn-Kroduction
In the process of study of reactions of living systems with a
different
level
of organization to millimeter waves,
non-thermal
(informational)
effects were discovered
[1-3].
The distance from
the place affected by the emission to the location of appearance of
the biological reaction may be hundreds and thousands times larger
than the distance at which the emission decreases one order of mag-
nitude.
This fact demonstrates participation of the nervous system
in perception of millimeter-range emission by living organisms.
There is a wide-spread opinion that biological effects of EHF
are
realized
in
humans
at
a
subsensory
level.
However,
in
the
recent years there
is interest to their sensory detection in the

form of radiosound, magnetophosphenes,
or skin sensations
[4-9].
Changes in EEC to EMF effects were most often observed in the
form
of
an
increase
in
the
slow
waves
and
spindle-shape
oscillations
in
reptiles,
pigeons,
rats,
rabbits,
monkeys,
and
humans
[10-12].
We have not found studies devoted specifically to the effects
of millimeter waves on the central nervous system in the available
literature;
thus,
the
current
study
has
been
undertaken.
This
study employed electrophysiological and psychophysiological methods
for the evaluation of the state of the central nervous system while
affected by EMF.
Methodology
Twenty healthy subjects
aged
to
40 years participated
in
the experiments.
Apparatus Yav-I with the wave length of
7.1 mm
was used as the EMF source.
A flexible waveguide with the power of
5 mW/cm2 at its end was directed at He-Gu
[4 Gi] acupuncture point
in the right or left hand of the subject.
Two experimental series have been conducted.
In the first one
(10
subjects,
tests with each
subject,
instances
of
field
action in each test),
sensory detection of the field was studied.
The length of the EMF signal
or control trial without the
signal
was
minute.
To
evaluate
the
subject's
EMF
sensitivity,
the
indicator
of
response
strength
(RS)
was
used,
i.e.,
the
ratio
between
the
number
of
correctly
identified trials
and
the
total
number of EMF
signals.
Another indicator used was the
level of
false
alarms
(FA),
i.e.,
the
ratio
between
the
number
of
false
