AAEM News:TEP: Cell Phones Do Cause Increased Brain Wave Activity in Some People

This is huge. A couple of oddities in the article
though. First the title and that It starts out
saying only 50% of the subjects had an EEG change
from cell phone exposure, but later explains that
every single one of them did, only about half
were more pronounced in the change. And why the
conjecture that sleeping people changed their
EEGs on purpose by stating that researchers don't
know if the change was physiological or psychological?

Abstract

Mobile phone exposure-related effects on the
human electroencephalogram (EEG) have been shown
during both waking and sleep states, albeit with
slight differences in the frequency affected.
This discrepancy, combined with studies that
failed to find effects, has led many to conclude
that no consistent effects exist. We hypothesised
that these differences might partly be due to
individual variability in response, and that
mobile phone emissions may in fact have large but
differential effects on human brain activity.
Twenty volunteers from our previous study
underwent an adaptation night followed by two
experimental nights in which they were randomly
exposed to two conditions (Active and Sham),
followed by a full-night sleep episode. The EEG
spectral power was increased in the sleep spindle
frequency range in the first 30 min of non-rapid
eye movement (non-REM) sleep following Active
exposure. This increase was more prominent in the
participants that showed an increase in the
original study. These results confirm previous
findings of mobile phone-like emissions affecting
the EEG during non-REM sleep. Importantly, this
low-level effect was also shown to be sensitive
to individual variability. Furthermore, this
indicates that previous negative results are not
strong evidence for a lack of an effect and,
given the far-reaching implications of mobile
phone research, we may need to rethink the
interpretation of results and the manner in which
research is conducted in this field.

Cell Phones Do Cause Increased Brain Wave Activity in Some People

Some people are more susceptible to brain wave
changes caused by cell phones than others.

BY MAKINI BRICE | JULY 31, 2012


For every person who embraces new advances in
technology whole-heartedly, there is probably one
who is suspicious be it microwaves, of Facebook
or cell phones. Now, research is showing that
both camps may be right: while cell phones do not
affect brain waves of everyone, some people may
be more susceptible to brain wave changes caused by cell phones than others


Previous studies had concluded that cell phones
do not impact brain waves at all, or only a
little. But this recent study has concluded that
for some people, cell phones impact brain waves a
lot, and that the averaging out of data has led
to erroneous conclusions for some people. In
addition, cell phones can impact brain waves
while people are awake or asleep. However, Rodney
Croft and his colleagues at the University of
Wollongong in Australia say also that these
differences in brain waves do not seem to have any health effects.


The research involved 20 participants who had
been used in previous trials on the subject.
During two consecutive nights, the volunteers
were exposed to cell phones for 30 minutes,
positioned over the right temporal region in a
cradle. (The right temporal lobe is located just
over the ear.) On one night, the cell phone was
on, and on the other, the cell phone was off,
though participants were not aware of when it was
on or off. Researchers found that exposure to
cell phones increased brain waves recorded by the
EEG in all individuals, but the difference was
more pronounced in certain groups of people. They
also found that the brain wave differences did
not seem to impact the quality of sleep.


Scientists wonder now about the source of the
differences. They speculate that the cause could
be either physiological or psychological.


Researchers have long cautioned
<http://www.cnn.com/2011/10/30/opinion/greene-smart-phone-addiction/index.html>against
users keeping their phones by their heads while
sleeping. For many people, however, it is a hard
habit to break. Many people, particularly young
people, use their cell phones as alarm clocks.
Since scientists do not know yet who is more
susceptible in changes of brain wave activity
without the use of an EEG machine, it is a habit that many of us should break.

They were asleep.  They did not know the cell phones were on.  And
they aren't sure whether they are making it all up?  Say whaaaaat?

However, nonsense like that is the norm for any disease people don't
want to exist.

The social phenomenon that underlies this is described here:

Wrong link.  Here is the correct link.

Nonsense attributions are the norm for any disease people do not want
to acknowledge as existing.
