Two private companies have announced that they will begin to offer "lie detection" services using Functional Magnetic Resonance Imaging (fMRI), as early as this summer. fMRI can produce live, real-time images of people's brains as they answer questions, view images, listen to sounds, and respond to other stimuli.
These companies are marketing their services to federal government agencies, including the Department of Defense, Department of Justice, the National Security Agency and the CIA, and to state and local police departments.
