Did you ever wonder what happens in the liar's brain when he attributes to himself, for example, your results and effort without taking into account your existence?
During the lying process, a large number of brain regions that contribute to logical thinking are involved. In particular, the prefrontal cortex, known as the cortex, is involved in complex cognitive processes.
In its scientific page, the French newspaper Le Monde devoted an article in which researcher Sylvie Chakroun highlighted the lie as a high-level intellectual activity, because the liar must first decide to hide or falsify truthful information, then create a false version of reality will defend and promote it, as So make sure that everyone believes his story, and that he saves his copy with vigilance so as not to contradict himself.
The researcher pointed out that these processes consume a lot of energy and mental presence, except for professional liars who have these processes automatically, noting that the prefrontal cortex, known for its responsibility for complex cognitive processes, is working to carry out these activities.
Two regions involved in the brain
As Maxim Kerev and his colleagues at the University of St. Petersburg showed in 2017, it is now possible to track how brain regions are activated and communicated according to the psychological context.
The researchers used this new method of functional MRI analysis to study how brain contact changes when someone lies or tries to manipulate while telling the truth, according to the researcher at the Swiss Institute for Scientific Research.
It appears that a coupling occurs within the left half of the brain between the middle frontal gyrus and the lower frontal winding during lying, and the connection between these two brain regions may reflect, according to the researcher, the conflict of choice for deceptive or impartial speech.
As for the manipulation behavior, it generates an increase in contact between the middle left frontal winding and the right temporal intersection that allows a person to position himself in place of others, which means that when manipulated us are seeing our vision more effectively.
The liar often ends up believing his lie, convincing him and possibly convincing others that he is telling the truth, but functional neuroimaging can lift the veil from this double lie to others and to the same person.

Researcher NGU and his colleagues at the University of Hong Kong have recently questioned whether fMRI can distinguish brain activity during manipulation and deception and during false memories, especially since these two experimental positions activate the left frontal fascia. They also activate a network of areas in both hemispheres, such as the upper right temporal winding, right obfuscation, left parietal lobe and upper left frontal winding.
The researcher in the laboratory of cognitive psychology concluded that fortunate real liars that there is nothing to suggest that this technique will discover lies in daily life.
Shukron concluded that a. Hayashi and his collaborators at Tohoku University have shown that the prefrontal cortex is the same in its ventral part when tolerated by scammers, so when someone tells you that they have deceived you in good faith, let your prefrontal cortex decide whether you should forgive it or not!
