I'm convinced that fMRI must be the gadget geek's ultimate toy as
Scientists are now using fMRI to scan brains for political cues. A few highlights:
"Last month, Drs. Joshua Freedman and Marco Iacoboni of the University of California at Los Angeles finished scanning the brains of 10 Republicans and 10 Democrats. Each viewed images of President Bush, John Kerry and Ralph Nader.
When viewing their favorite candidate, all showed increased activity in the region implicated in empathy. And when viewing the opposition, all had increased blood flow in the region where humans consciously assert control over emotions -- suggesting the volunteers were actively attempting to dislike the opposition."
"And when voters were shown a Bush ad that included images of the September 11 attacks, the amygdala region of the brain -- which lights up for most of us when we see snakes -- illuminated more for Democrats than Republicans. The researchers' conclusion: At a subconscious level, Republicans were apparently not as bothered by what Democrats found alarming."
