Wired talks about the American Neurological Association's annual meeting, covering brain imaging techniques. Volunteers' reactions:
""I felt like I'd fallen asleep while sucking on tinfoil," said one volunteer from California.
""I had a metallic taste in my mouth for hours. But it was cool to see how my brain ordered my legs to move, how it worked and processed data when I read a book, spoke or touched different objects."
"Another anonymous volunteer said he saw flashes of light and felt "loopy" for a half hour after the scan." [more, via Wired]
