A scientific paper includes a brain image showing that memory regions are active when research participants tell practiced lies but not when participants tell spontaneous lies. What would you expect this image to be?
A) An MRI image showing activity in the prefrontal cortex
B) An fMRI image showing activity in the limbic system
C) A PET scan image showing activity in the occipital lobe
D) A CT scan image showing activity in the parietal lobe

An fMRI (functional magnetic resonance imaging) image is used to detect changes in blood flow, indicating brain activity. It is commonly used in studies investigating human cognition, perception, and behavior. The limbic system is a collection of structures in the brain that are involved in memory and emotion, making it a likely area to be active in a study about lying and memory. Additionally, the prefrontal cortex is generally associated with decision making and planning, making it a plausible option, but not as likely as the limbic system. The occipital and parietal lobes are not directly related to memory or lying and would not be expected to show activity in this type of study.
