.......More research from EMF-L.......

Drs.  "Tony" Sastre and "Chuck" Graham are both well recognized within
the EMF research community for their integrity and the quality of their
work......

Actually, their lab -- Midwest Research of Kansas City, Missouri -- has
conducted previous research along this line.  Some of the previous studies
also showed various brain activity when exposed to EMF.....  Then, as now
(below), they used human subjects -- which just about makes their work 
unique in the EMF community!  Then, as now (below), the number of subjects 
was/is necessarily small.....  So, all of the Moulder-like industry/goverment 
zombies have continued to ignore the implications of the Midwest Research 
Institute's important, consistent (and potentially highly significant) 
findings.......guru.......

Brain frequency magnetic fields alter cardiac autonomic control mechanisms.

Objective: Heart rate variability (HRV) is a noninvasive indicator of
sympathetic and vagal cardiovascular control known to be tightly correlated
with sleep stages. Recent studies indicate that HRV in humans is altered by
nocturnal exposure to power-frequency (60 Hz) magnetic fields. Given the
central origin of autonomic cardiac control, we determined if field exposure
in the beta(1) EEG/MEG frequency range was a more effective stimulus for HRV
alteration than 60 Hz fields, and explored the mechanisms involved.Methods:
Healthy young men were exposed (n=9) overnight to an intermittent magnetic
field (16 Hz, 28.3 microTesla, muT), or sham exposed (n=9), under blind test
conditions in a laboratory exposure facility.Results: Field exposure was
associated (P
