Foreman and Kutner caught Sophia lying about her parents because her limbic system was active when she was talking about their death, which they said is an area involved in imagination and wouldn't have been active had she been telling the truth. This may be true of a specific part of the limbic system, but the way they said it is false, because the limbic system is responsible for emotions, which would be very active when talking about one's parents dying.
