Transcranial magnetic stimulation (TMS)

[Dirk Bruere at Neopax]

Anyone any info on the circuit designs used etc?

Here are some references off google in case anyone thinks it's xtal power mk2

One other bit of info I have just come across:
"Engineering safety - TMS equipment operates at lethal voltages of up to 4 kV.
It is hence important not to keep coffee cups or ice bags on the stimulator. The
maximum energy in the capacitor is about 500 J, equal to dropping 100 kg from 50
cm on one's feet. An electrical engineer with experience of low-power
electronics only should keep his/her hands behind the back and ask a power
electronics expert to do the job."

It is definitely a real technology. I would not recommend it as a
do-it-yourself project. What if it induces a seizure?

Well, dumping a few hundred joules in around a millisecond into a coil on the
head will certainly do something.
However, I'm more interested in the effects of much smaller fields, esp with
respect to temporal lobe stimulation.

Same here. I wonder if there's a newsgroup for DIY experimenters? I
don't fancy experimenting on myself, but if others are up for it I'll
happily read their reports!

This is the 'hard stuff'

The original stuff done by Persinger is particularly interesting and looks easy
to replicate

Maybe something like this
http://www.innerworlds.50megs.com/

Particularly, I'm interested in creating larger fields eg room sized

Following on, this also looks interesting
