Psychopathic traits and neurophysiology of deception

Background: Recent neuroimaging studies have suggested that prefrontal cortical regions are involved in the neural control of deception. However, to overcome the correlative restrictions of these studies Karim et al. (2010) have investigated the effects of modulating cortical excitability by transcranial direct current stimulation (tDCS) and have shown that inhibition of the frontopolar cortex (BA9/10) can facilitate skillful lying and decrease skin conductance response (SCR) and feelings of guilt while deceiving an interrogator of a mock crime. Whereas these findings support the hypotheses that a dysfunction of…
