Transcranial magnetic stimulation (TMS)

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."

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 :-)

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

Speaking of things happening with strong magnets ...

Following on, this also looks interesting
