WASHINGTON (Reuters) - Brain scans show that the brains of people who are lying look very different from those of people who are telling the truth, U.S. researchers said on Monday.
The study, using functional magnetic resonance imaging or fMRI, not only sheds light on what goes on when people lie but may also provide new technology for lie-detecting, the researchers said.
"There may be unique areas in the brain involved in deception that can be measured with fMRI," said Dr. Scott Faro, director of the Functional Brain Imaging Center at Temple University School of Medicine in Philadelphia.
"There may be unique areas in the brain involved in truth-telling," Faro added at a news conference.
Faro and colleagues tested 10 volunteers. Six of them were asked to shoot a toy gun and then lie and say they didn't do it. Three others who watched told the truth about what happened. One volunteer dropped out of the study.
While giving their "testimony," the volunteers were hooked up both to a conventional polygraph and also had their brain activity imaged using fMRI, which used a strong magnet to provide a real-time picture of brain activity.
There were clear differences between the liars and the truth-tellers, Faro's team told a meeting in Chicago of the Radiological Society of North America.
"We found a total of seven areas of activation in the deception (group)," he said. "We found four areas of activity in the truth-telling arm."
Overall, it seemed to take more brain effort to tell the lie than to tell the truth, Faro found.
Lying caused activity in the frontal part of the brain --- the medial inferior and pre-central areas, as well as the hippocampus and middle temporal regions and the limbic areas. Some of these are involved in emotional responses, Faro said.
During a truthful response, the fMRI showed activation of parts of the brain's frontal lobe, temporal lobe and cingulate gyrus.
Faro said the study was small and limited. Volunteers were not asked to try especially hard to deceive the equipment, he said -- noting that it has been documented that some people can fool a polygraph using various techniques.
Using fMRI as a lie detector is expensive, but it may be worthwhile in some cases -- such as trying to question a terrorism suspect, or in a high-profile corporate crime case, Faro said.
LOL!! I was thinking of them when I read the article! Can you imagine what Bubba's brain would look like???
Neither Bill or Hill are even good liars. They just have a bunch of sheeple who want to believe them.
A pair of "PAGLEGS" if ever I've seen 'em.
Well, let's find out, shall we?
The cost of employee theft is passed on to consumers.
Swell. More grist for the sweat merchants.
let's put a few million into this. and keep several billion out of scumbag lawyers pockets!!
If you could look inside Bubbas head all you would see is millions of little pu**ies
Like James Carville, Terry McAullife, Dan Rather, and George Stephanopolis, to name a few....
Vive La Difference !
Well, clinton was not a particularly good liar. But I always had a somewhat humourous take on lying since I worked with kids. One day a colleague and I were discussing a student who was pretty challenged, could barely put two words together to make a sentence. But he had told me a beautiful whopper. A story with a beginning, ending, middle and a cast of characters that was quite inventive. He was headed for big trouble, which is why he told me the story. And I just nodded until he wound up. I wanted to see just how far he could take his yarn.
Anyway, I allowed to my friend that perhaps lying was a completely different intelligence. And wasn't it too bad we couldn't harness that intelligence for normal learning. Cause this kid had some real potential. Oh well...
Moral Absolutes Ping. Hmm, food for thought. I noted the article said it is harder to lie than tell the truth. Lies are always harder to remember, too.
I read once that a liar's footprints defile the earth. Or words to that effect.
I have noticed that when people lie a little, they usually really lie a lot. It is definitely a very bad habit and character fault. Of course, if an intruder breaks into your house and inquires as to the location of the childrens' bedrooms, best to lie, while aiming your firearm unnoticeably.
let me know if anyone wants on/off this pinglist.
I always wondered why I had such a highly developed cingulate gyrus. People are always commenting upon that fact.
Detectives of the Bucks County Police Deaprtment were hellbent on getting a confession out of the suspect. But instead of resorting to the old rubber hose approach they put technology to use. They clearly [sic] converted the office Xerox machine into a lie detector.
First, the supersleuths put a card saying "He's lying" into the machine. Then they put a metal colander (normally used to drain spaghetti) over the suspect's head. Next, they wired the colander to the Xerox machine.
When the suspect gave an answer the detectives didn't believe, the officers pushed the copy button and the machine spewed out a paper which read, "He's lying." Faced with such advanced-level police tactics, the fellow finally confessed.
When the judge heard all of the details, he ordered that the criminal charges be dropped and the suspect released. Lucky for him there's no law against gullibility.
I like the practical applications of this. On the other hand, I don't like the fact that I might not be able to get away with lying anymore.
Hehe...Monica probably knows!
Alright buddy. Put your brain back in your pants.
