Which techniques are commonly used to study deception through neuroimaging?

• A. Polygraph and voice stress analyzer
• B. PET and CT
• C. fMRI and EEG brain fingerprinting
• D. ERP and MEG

Answer: (C)

When studying deception with brain imaging, the goal is to capture both where in the brain deception-related processes occur and when those processes unfold. fMRI provides high spatial resolution, showing which brain areas—often parts of the prefrontal and cingulate networks—are engaged when a person lies or withholds information. EEG offers excellent temporal resolution, revealing fast neural responses to deceptive stimuli and enabling methods that detect concealed information patterns. Brain fingerprinting is an EEG-based approach that looks for specific neural signatures linked to recognition of known information, which can be used in deception contexts. This combination—a spatially precise imaging method with a temporally precise EEG-based technique—best reflects how neuroimaging is commonly used to study deception. The other options mix non-imaging lie-detection tools or pair modalities not typically used together for deception research, such as anatomy-focused CT with PET or combining ERP with MEG, which is less representative of the standard neuroimaging approach to deception.
