title: [fMRI study of deliberate deception].
abstract: The aim of the present research was to study the deliberate deception. Event related functional magnetic resonance (fMRI) imaging technique was used to assess the changes in functional brain activity by virtue of recording blood oxygen level dependant signal (BOLD-signal). 12 right-handed healthy volunteers aged 19-44 participated in the study. BOLD images were acquired in three different experimental trials. There were deliberate deception, manipulative honest and control truthful trials (catch trials). The main finding of the present study is that the deliberate deception and manipulative honest actions in comparison with instructed truthful responding was characterized by BOLD signal increase within the anterior cingulated cortex (ACC), frontal and parietal areas as well. Comparison of present fMRI data with results demonstrated in our previous research implemented with event related potentials technique points to the involvement of the brain mechanism of error detection to brain processing of deliberate deception.
