Thinking about TCMS

I am referring to trans-cranial magnetic stimulation–that other major killer-app besides brain imaging that’s come out of the neurotechnology revolution. Think of it as a way to reach out and “touch” an ensemble of neurons without the need for them to “see air” (i.e. neurosurgery). Essentially electrical stimulation of the brain without electrodes (in the brain).

My question has to do with the slightly more esoteric question of whether such stimulation, when appropriately tuned to characteristic firing modes of neuronal groups (say theta –or 4 to 8 Hz) can either tweak or eliminate such characteristic synchronous oscillatory activity.

Any takers out there?
