fMRIand Deception Detection

Abstract

To date, fMRI studies are beginning to define which part of the brain may be implicated in deception. However, the science is in its nascent stage, and many more large‐scale studies are needed to assess the reliability of the evidence, especially when used to detect deception in single individuals. Although there have been efforts to introduce such evidence into court, courts have been resistant to these efforts as there remain numerous questions involving evidentiary reliability, constitutional implications, and jurisprudential concerns that must be considered before such evidence should become admissible in trials.
