How Do You Measure the Effects of TMS in Primary Motor Cortex?

Most of what we know about the physiology of t m s and these change in magnetic fields comes from motor cortex, because we can more easily measure the effects. We don't really know if that's the same effect when you move the coil to the frontal cortex, or to the cerebellum, or other brain regions. And it's not as simple as you're exciting the tissue or inhibiting the tissue. Depending on those network of facts and what the sights connected to, your ten herds, t m s might be excitetr or might be inhibitory. I think the only thing that people have begun to understandand this is where conicactivity comes in, is that the focus
