Functional MRI-based lie detection: scientific and societal challenges

| 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, re...

Commentary: functional MRI lie detection.

Functional brain imaging with magnetic resonance is a useful research tool for showing regional metabolic changes with ongoing brain activity. Use of functional imaging to study the anatomy and function of various brain areas has recently been applied to the examination of the emotional life of patients including those with anxiety, panic, or depression. The application of this technology to th...

Functional MRI lie detection: too good to be true?

Neuroscientists are now applying a 21st-century tool to an age-old question: how can you tell when someone is lying? Relying on recently published research, two start-up companies have proposed to use a sophisticated brain-imaging technique, functional magnetic resonance imaging (fMRI), to detect deception. The new approach promises significantly greater accuracy than the conventional polygraph...

Functional Magnetic Resonance Imaging Lie Detection: Is

Lie detection by functional magnetic resonance imaging.

The accurate detection of deception or lying is a challenge to experts in many scientific disciplines. 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...
