New essays examine the use of fMRI to recognize deceit

Cambridge, Mass.June 8, 2009The American Academy of Arts and Sciences has published a volume of essays, "Using Imaging to Identify Deceit: Scientific and Ethical Questions," examining the scientific support for using functional magnetic resonance imaging (fMRI) to recognize deception. The seve...

Decoding short-term memory with fMRI

People voluntarily pick what information they store in short-term memory. Now, using functional magnetic resonance imaging (fMRI), researchers can see just what information people are holding in memory based only on patterns of activity in the brain. Psychologists from the University of Oregon ...

Brain Is More Active While Hiding The Truth, Reveals fMRI Imaging

Functional magnetic resonance imaging (fMRI) can help identify if an individual is lying much better when compared to the traditional polygraph tests. // The test further highlights certain specific brain regions that light up when a person tells a lie.
