Hi Roy,

I have been keeping loose tabs on this technique, which they in the trade call
"transcranial magnetic stimulation" (TMS).  A lot has appeared on the Internet
since I last searched - today's infoseek.com search gave me 482 hits.  Below
are a few links to learn all about TMS, which usually involves application of
one or more millisecond-long pulses of a very strong (> 1 T) magnetic field. 
For therapeutic purposes, they are using "rTMS" where the "r" stands for
"repetitive" or "rapid"; the latest equipment is able to recharge the
capacitors fast enough to pulse the field on and off at fequencies up to 50
Hz.  Research is being done at NIMH and elsewhere.

Since the magnetic fields being used here are extremely large, I don't think
that this provides us with any amunition in the fight against electrosmog,
except just to point out to people (nothing new) that large fields do have
profound physiological effects.  However, I have personally experienced a much
more delicate therapy called EEG-driven photic stimulation that uses only very
miniature light bulbs that produce miniscule fields (how big is something I
believe they are measuring now) and is active for a wide variety of conditions
including depression.  The fact that this works at all is impressive, although
based on currently available research an optical (as opposed to
electromagnetic) mode of action can be ruled out.  For information on this
interesting work, I direct you to the web site of Len Ochs, Ph.D:
www.flexyx.com.
