During an interrogation, an fbi agent tries to scare a suspect into making a confession by saying "you know, they have this new type of lie detector that can measure activity in different regions of the brain to determine whether a person is lying or telling the truth." what technology is the agent referring to?

The answer is functional magnetic resonance imaging or functional MRI (fMRI). This measures mind movement by identifying changes related with blood stream. This strategy depends on the way that cerebral blood stream and neuronal actuation are coupled. At the point when a region of the mind is being used, blood stream to that locale additionally increments. The essential type of fMRI utilizes the blood-oxygen-level ward (BOLD) differentiate, found by Seiji Ogawa.
