A scientist is interested in understanding how the size of the prefrontal cortex changes between the ages of 9 and 13. Which of the following brain imaging techniques would she be most likely to use?
A) Electroencephalography (EEG)
B) Functional magnetic resonance imaging (fMRI)
C) Magnetic resonance imaging (MRI)
D) Transcranial magnetic stimulation (TMS)

Question

Quizplus · Accepted Answer

Magnetic resonance imaging (MRI) is a technique that can provide detailed images of the brain's structures, including changes in the size of specific regions. It is non-invasive and can be used to study brain development over time, making it the best choice for this experiment. EEG measures electrical activity in the brain, fMRI measures changes in blood flow and activity, and TMS involves stimulating the brain with magnetic pulses, but none of these techniques provide detailed information about the size of brain structures.
