Brain mapping regions associated with fMRI lie detection

Objective: One newly and hopeful area of investigation is non-invasively measures through functional MRI (fMRI) detection of brain activity in deception. This study uses a mixed-design paradigm test to analyze the activity of brain regions involved in suppression of truth and lie after a mock crime. Methods: This study was undertaken in 8 healthy subjects, aged 21 to 36. We instructed the subjects to commit a mock crime in a laboratory setting, consisted in steel a ring or a watch (ring-watch) located in a drawer and take the object to a locker. We applied a mixed-design test (control, neutral and ring-watch que…
