Concerns about the validity of the comparison question test (CQT) will continue to create controversy until a well-validated theory is developed that explains how the polygraph test detects deception. One theory that provides a plausible explanation states that deceptive behavior on the CQT and corresponding physiological arousal on the polygraph are associated with neural activation in areas of the brain that process personally-relevant, emotionally-arousing information. Although the… 
Study of Neurocognitive Processes in a Paradigm of Information Concealment
The work announces the creation of a technology for complex fMRI-MRIcP neurocognitive researches, promising for use in the interests of fundamental science and for a number of branches of practice.

The Blue Fairy in Pinocchio stated confidently, “Lies can be easily recognized”, but was wrong when it comes to humans, who are in general poor lie.
National security behavioral detection: a typography of strategies, costs, and benefits
Scholars of transportation and homeland security have begun to assess the relative costs and benefits of specific national security programs. Two programs that have generated significant attention in


Covariations among fMRI, skin conductance, and behavioral data during processing of concealed information
Using parametric analyses, reaction times and SCR amplitudes were found to be linearly related to activity in the cerebellum, the right inferior frontal cortex, and the supplementary motor area, providing a first link between behavioral measures, sympathetic arousal, and neural activation patterns during a GKT examination.
Brain Activity during Simulated Deception: An Event-Related Functional Magnetic Resonance Study
The results indicate that cognitive differences between deception and truth have neural correlates detectable by fMRI, inhibition of the truthful response may be a basic component of intentional deception, and ACC and SFG are components of the basic neural circuitry for deception.
Detecting Deception Using Functional Magnetic Resonance Imaging
Validity of the Lie Detector
The profession of polygraphy uses physiological measures to improve the detection of deception. The science most relevant for assessing the utility of these measures is that of psychophysiology. This
Lie detection by functional magnetic resonance imaging
To investigate if specific cerebral activation characterized feigned memory impairment, six healthy male volunteers underwent functional magnetic resonance imaging with a block‐design paradigm while they performed forced‐choice memory tasks involving both simulated malingering and under normal control conditions.
A pilot study of functional magnetic resonance imaging brain correlates of deception in healthy young men.
Individually and as a group, EDA correlated with blood flow changes in the orbitofrontal cortex and anterior cingulate, but individual results were not consistent.
Behavioural and functional anatomical correlates of deception in humans
Lying was associated with longer response times and greater activity in bilateral ventrolateral prefrontal cortices and Ventrolateral cortex may be engaged in generating lies or withholding the truth.
Neural correlates of different types of deception: an fMRI investigation.
Deception is a complex cognitive activity, and different types of lies could arise from different neural systems. We investigated this possibility by first classifying lies according to two
What Is the Current Truth About Polygraph Lie Detection?
With reference to the continued debate about polygraph lie detection, this article applies standard criteria of scientific validity to the most common and influential polygraph procedure, the Control
