New research is using functional MRI (magnetic resonance imaging), a scan of the brain that highlights specific areas of the brain that are used during certain tasks, such as taking a lie detector test. Explain which area (s) of the brain you think might light up to show that you are telling a lie or telling the truth. Explain your reasoning.

The frontal lobe and the medulla oblongata
