Dr.Clay is studying the function of the fusiform face area,and comparing activation when participants view faces that they know versus faces of strangers.Given the choices of techniques below,what is the best one for Dr.Clay to use?
A) diffusion tensor imaging
B) MRI
C) event-related potential
D) positron emission tomography

Question

Quizplus · Accepted Answer

Positron emission tomography (PET) is the best choice for Dr. Clay to use as it allows for the measurement of blood flow and metabolic activity in specific brain regions. This can help to identify which regions are specifically activated when viewing faces that are known versus faces of strangers. Diffusion tensor imaging (A) is a technique used to measure the structural connectivity of different brain regions, which would not be as useful in this case. MRI (B) is primarily used for structural imaging and may not be sensitive enough to detect differences in activation between known and unknown faces. Event-related potential (C) measures the electrical activity of the brain in response to specific stimuli and may not be as effective in identifying the specific brain regions involved in processing faces.
