Does fMRI Lie Detection Have a Future in the Courtroom?

Background Functional Magnetic Resonance Imaging (fMRI) is a brain imagining technique developed in the 1990’s based on blood oxygenation levels in the brain. The underlying property upon which fMRI relies is hemoglobin’s tendency to exhibit different magnetic properties when oxygenated than when deoxygenated. By inducing a strong magnetic field on the subject and observing how the hemoglobin responds to the field, neurologists can determine which parts of the brain are experiencing greater blood flow during Continue Reading →
