Lie Detection: fMRI

Objective detection of deception was extensively studied, starting from polygraph to more modern techniques, the functional MR (fMRI), and they are based on neural (sympathetic) activation that is evoked in stressful conditions, such as lying. The role of fMRI in neurophysiology has been extensively developed and studied, and its principles lie in the correlation between the brain demand of energy during determined task and its supply. Although being extensively studied, its role for judiciary purpose presents many shortcomings.
