Mindhacks pointed me to an awesome TED talk by Rebecca Saxe on how humans are able to read other people's mental states. We can thank the right temporal parietal junction for this. I like this talk because its neither dry nor boring and has some interesting implications. Rebecca applies TMS (transcranial magnetic stimulation) to participants heads, temporarily suspending the activity in the RTPG, and sees what happens. It's fascinating- go check it out now! (it's only 15 minutes). The most interesting part may be the questions at the end.
