Human brain available 'machine' lie detector

People have two distinct areas of the brain to deal with suspicions, in which the second brain region only "lights up" when encountering people we feel disbelieving.

Scientists at Virginia Carilion Research Institute (USA) have found that our skepticism and suspicion 'live' in the amygdale brain region - which plays a central role in dealing with fear and emotional memories, along with the parahippocampal gyrus brain region , which is associated with memory and visual reminiscence.

People have evolved into "innate skeptical" creatures?

First, suspecting that an 'emotion' and volunteers - which were wired to an MRI scanner - showed that the activity in the amygdale brain region was in charge of fear.

But soon after, another area lit up and that was p.gyrus . 'It seems that humans have evolved to be always skeptical creatures,' said Read Montague, director of the Neuroscience Laboratory at Carilion Research Institute on DailyMail.

'What surprised us was when someone's behavior raised suspicion, the p.gyrus brain region also lit up and acted as a natural lie detector'.

However, according to Mr. Montague, tests on buying and selling also show that not trusting others is not always a good starting point.

'Thoughtful people are suspicious of the high level easily ignoring the information provided by the buyer and therefore they ignore potential profits'.

In fact, according to scientists, the ability to recognize reliable information in a competitive environment is just as important as 'sniffing' unreliable behaviors.
