We got to play with one last week in my biopsych class. Pretty fun stuff. My primary motor cortex was stimulated, causing my hand to uncontrollably clench etc... It was only a single pulse TMS so there was no going deaf or anything. Some people can see phosphemes (round blueish-green bubble things) when their viual cortex is zapped though.
