"A slew of studies and at least one commercial product are aimed at using neural activity in lie detection. Penn psychiatrist Daniel Langleben is using fMRI to identify brain regions associated with lying. He and his team have concluded that "cognitive differences between deception and truth have neural correlates detectable by fMRI ;' with increased activity in the "anterior cingulate cortex （ACC）, the superior frontal gyrus （SFG）, and the left premotor, motor, and anterior parietal cortex [sic] ... specifically associated with [deception]:' Happily, it's beginning to look as if we are wired to tell the truth. A review of studies on the use of fMRI to detect lying reports that attempts to deceive are associated with activation of executive function centers, especially the prefrontal and anterior cingulate cortices, but truthful responses don't activate any particular areas more than others. "Hence;' a University of Sheffield neuroscience group concludes, "truthful responding may comprise a relative 'baseline' in human cognition and communication:' Techniques aren't yet specific enough to predict when a particular person is being intentionally deceptive. However, there are some indications that refinement of fMRI for lie detection is possible, based on the fact that our natural inclination to be truth fullorces the brain to work harder when we lie. Harvard's Giorgio Ganis and Stephen Kosslyn have found that well organized lies involve activation of many parts of the brain-a convincing ‾e requires concentration-and rehearsed lies can be distinguished from spontaneous ones. Similarly, a Medical University of South Carolina team found increased activity among lying young males in the anterior cingulate and the orbitofrontal cortex. The forensic and national security implications of a reliable individual brain scan for lie detection are obvious"（Moreno 2006:103-104）.
