Gb. Bell et al., FREQUENCY-SPECIFIC RESPONSES IN THE HUMAN BRAIN CAUSED BY ELECTROMAGNETIC-FIELDS, Journal of the neurological sciences, 123(1-2), 1994, pp. 26-32
The effects of 1.5- and 10-Hz electromagnetic fields (EMFs), 0.2-0.4 g
auss, on the intrinsic electrical activity of the human brain at these
frequencies was studied. Each of 19 subjects exposed for 2-sec epochs
exhibited altered brain electrical activity at the frequency of the E
MF during the time of stimulation, as determined by spectral analysis
of the electroencephalogram. Since brain activity at specific frequenc
ies could be altered by applied EMFs, the results suggest that it may
be possible to use EMFs to determine whether particular intrinsic freq
uencies subserve specific physiological or behavioral responses.
