Why is magnetoencephalography (MEG)more useful than functional magnetic resonance imaging (fMRI)for studying participants' responses to quiet sounds?
A) MEG equipment is much cheaper and easier to use than fMRI equipment.
B) The magnets used in fMRI are very noisy, blocking the ability to sense quiet sounds.
C) MEG recordings of brain activity must be taken more slowly than fMRI images, allowing a more accurate assessment of brain activity.
D) Neither of these technologies is suitable for assessing participants' responses to sound.

Quizplus · Accepted Answer

The magnets used in fMRI are very noisy, making it difficult to detect and study responses to quiet sounds. MEG is a more suitable method for studying these types of responses. The other options are incorrect.
