The Science of Deception and fMRI Lie-Detection

Deception has long been of interest to humans, but only recently has the neuroscience of deception started. Similarly, lie-detection, as an applied aspect of the study of deception, has long been studied but only with the advent of imaging techniques and the development of the neuroscience of deception has it become possible to develop techniques based on scanning our brains. Currently, both areas suffer from methodological and philosophical problems. As an applied science fMRI lie-detection has greater issues to deal with, specifically legal and ethical issues. Despite interesting results, implicating frontal regions as the neural correlates of deception, the neuroscience of deception need better designs and more study to be able to draw any general inferences. By its nature fMRI lie-detection suffers greatly from this, and additional problems concerning privacy and legality make it seem too early to implement it in court or anywhere, as stated by many scientists. On the other hand the technology already exists and is likely to be used.
