Functional MRI (fMRI)-based lie detection has been marketed as a tool for enhancing personnel selection, strengthening national security and protecting personal reputations, and at least three US courts have been asked to admit the results of lie detection scans as evidence during trials. How well does fMRI-based lie detection perform, and how should the courts, and society more generally, respond? Here, we address various questions — some of which are based on a meta-analysis of published…

fMRI and Lie Detection
TLDR
A closer look is taken at the potential and pitfalls of fMRI lie detection techniques, providing insight into the areas of the brain involved in lying, the impact of memory on deception, how countermeasures may foil the authors' efforts to detect lies, and factors that can create cause for concern about experimental validity.
Functional MRI-based lie detection: scientific and societal challenges
TLDR
An incorrect paper was cited as reference 2 of this article and lying in the scanner: covert countermeasures disrupt deception detection by functional magnetic resonance imaging was cited.

First invented in 1921, polygraph, also known as the lie detector, is a machine that has been used mainly in criminal trials, but not without controversy. In the past few years, however, and thanks…
Deception detection based on neuroimaging: Better than the polygraph?
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…
Deception detection with behavioral, autonomic, and neural measures: Conceptual and methodological considerations that warrant modesty.
TLDR
It is argued that the Comparison Question Test currently applied in many countries has weak scientific validity, which cannot be remedied by using neuroimaging measures, and paradigms are promising, but the absence of data from ecologically valid studies poses a challenge for legal admissibility of their outcomes.
Are We Ready for an Expanded Use of Neuroscientific Evidence in the Courtroom
TLDR
Electroencephalography, positron emission tomography and functional magnetic resonance imaging are all appropriate techniques for examining the working brain despite being scientifically valid.

  • 2014
TLDR
The most commonly voiced criticisms of functional neuroimaging are reviewed and it is argued that in some cases the kernel has been over extended in ways that are inaccurate or misleading.
Limitations of Brain-based Lie Detection
Brain-based lie testing methods are still very much in the experimental phase, and it is not yet proven whether there is any method that directly examines the human brain that is suitable for lie…

TLDR
This review starts with the premise that even though the SVT/PVT task is designed to be simple and easy to perform, it nonetheless requires intact frontoparietal attention, working memory and task engagement (motivation) networks, and if there is damage or pathology within any aspect of these networks as demonstrated by neuroimaging findings, the patient may perform below the cut-point as a result of the underlying damage or pathophysiology.

Lie detection by functional magnetic resonance imaging
TLDR
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.
Telling truth from lie in individual subjects with fast event‐related fMRI
TLDR
This study presents the first quantitative estimate of the accuracy of fMRI in conjunction with a formal forced‐choice paradigm in detecting deception in individual subjects and uses a paradigm balancing the salience of the target cues to elicit deceptive and truthful responses.
Behavioural and functional anatomical correlates of deception in humans
TLDR
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.
Detection of deception using fMRI: Better than chance, but well below perfection
TLDR
Although brain imaging is a more direct index of cognition than the traditional polygraph, it is subject to many of the same caveats and thus neuroimaging does not appear to reveal processes that are necessarily unique to deception.

TLDR
The ethical, legal, and social issues raised by advances in functional neuroimaging are challenging and somewhat distinctive, but they are not entirely new.

TLDR
The authors neither invented lie detection technology nor can do much about the need for it, they have just devised a more reliable version, and it is the public and its representatives to help gauge when they are approaching a danger zone.
