There is a lot in medline and medical textbooks. The mechanism is plain induction, stimulating or inhibiting cortical neurons (exactly what happens depends a bit on neural connectivity and responsiveness, as well as the field geometry).

My guess is that the effect is similar to ECT, in that it stimulates the brain to produce more NGFs, or possibly that it kicks it out of bad attractor states.

After all, nuclear magnetic resonance imaging is based on finding the sacred frequencies of the spin-spirits so that they can sing about how the hidden things are... :-)

Definitely. Take a look at the image at - it is quite clear that the effect is widespread. Quite nice move over to the contralateral hemisphere across the corups callossum.
