.......Marge, re cell-phone and auto accident causation (which you
refer to briefly below) -- I cannot imagine that you intend to impute
ALL such causation to the possible bioeffects?? Surely you do also
recognize the role that such cell-phone activity (while driving) may
create ... simply by DIVERTING the driver's attention away from what
he/she should really be more attentive to: the roadway and other
vehicles??......
It is my impression that the later "inattentiveness" is the real concern
of those city or state laws (like the one in Ohio) to which you and others
have referred on this network.... They are not (yet) even aware of the
possible effects upon the brain of any bioeffects that may be occuring....

Subject: Digital phone effects on brain: REM sleep
Here is an interesting German-language study I found; I wonder if anyone
literate in German in our group might undertake a roungh translation of it for
the group. [There is an English abstract on Medline.]
Wiener Medizinische Wochenschrift, vol. 146. no. 13-14, 1996, pp. 285-286.
K. Mann & J. Roschke. REM-Suppression unter dem Einfluss digitaler
Funktelefone [REM suppression induced by digital mobile radio telepones]
The investigators studied the effects of pulsed high-frequency electromagnetic
fields emitted by digital mobile radio telephones on sleep in healthy humans.
They found a REM-suppressive effect: reduction in the percentage of, and in
the duration of, REM sleep. [REM sleep is a stage of sleep in which there is
rapid eye movement: REM. It is associated with dreaming, because people
awakened during REM sleep almost always report that they were dreaming when
awakened.] Spectral analysis revealed an increased spectral power density of
the EEG signal -- especially in the alpha frequency band -- during REM sleep.
Another English-language paper by the same authors discusses this topic and
explicitly addresses the implications for learning. REM sleep is believed to
be valuable because it helps to integrate and assimilate knowledge gained
during the day, thus facilitating learning. Therefore negative effects of
cellphone radiation on REM sleep may indicate similar negative effects of this
radiation on ability to learn when awake. The English-language paper is
Neuropsychobiology, vol. 33, no. 1, 1996, pp. 41-47. Effects of pulsed
high-frequency electromagnetic fields on human sleep.
Both these papers were published three years ago. Isn't it interesting that
there seems to have been little attention paid to their implications by any
regulators, or even the wireless telecommunications industry! It seem to me
that there is a clear relevance to the recent reports linking car crashes with
the use of cellular phones (I suspect it's always digital phones, never analog
ones). -- Marjorie
P.S. I recently read, but have no confirmation, that "only two states" in the
USA require that a traffic accident report indicate whether the use of a
cellular phone was involved. Anybody know which two states?
