For me, the strongest effect was after one particular region (they tested many), in this TMS study they were targeting 1cm^3 of the brain at a time. The effect that was most pronounced for me was a greatly enhanced sense of sound after one of the regions was targeted. I'm already an auditory thinker, I can remember dialogs, sounds, etc and re-listen to them in my mind. I don't visualize easily at all. I first noticed the effect while walking around Boston on a break from testing, and being somewhat overwhelmed by the distinctness of all of the sounds around me - the people walking and talking, the engines of the taxis, the birds, etc. Each was like a separate track that I could isolate and focus on. As I said, I already think of myself as being a strongly auditory thinker, but it was like this dial had been turned up to 11. I vividly remember driving back from the TMS lab while listening to a live performance and easily counting how many singers were in the chorus. This wasn't permanent, but very memorable.

The regions they target have fairy specific effects. While the most memorable to me dealt with sound, another memorable one made us measurably faster at responding to an emotional categorization test. In this test you have a picture of part of a face (eyes or mouth) flashed in front of you for a split second, and you have to decide which of several emotions it represents as quickly as you can.

In short, TMS can affect vastly more than just emotional blindness. But the research is still young, and it's going to take time for it to be further developed into its full potential.
