Question

Dr. Jamison studies the part of the brain that is active when people are lying. She asks half of her participants to tell the truth about an event from their childhood and half to tell a lie about a childhood event. Which of the following brain imaging techniques should she use to detect brain areas that are active when participants are lying?A.an electroencephalograph (EEG)
B.functional magnetic resonance imaging (fMRI)
C.polygraph (lie detector machine)
D,magnetic resonance imaging (MRI)

Answer 1

Answer:

B.functional magnetic resonance imaging (fMRI)                                                                                                        

Explanation:

Functional magnetic resonance imaging: The term functional magnetic resonance imaging is also referred to as functional MRI which is responsible for measuring an individual's brain activity via detection of changes related to the blood flow. It is based on the phenomenon which states that the neuronal activation and cerebral blood flow are considered as coupled. The blood flow in the area of the brain increases if its in use.

In the question above, the given statement represents the functional magnetic resonance imaging.
