John hears a musical song while in an fmri. the researcher tells john that his left hemisphere was more activated true or false?
a. true
b. false

The given statement is correct and hence

a. True

Explanation:

Functional Magnetic Resonance Imaging (functional MRI) or fMRI can be explained as the technique which measures activity of brain on the basis of detection of changes with blood flow. fMRI is based on the fact of coupling of  neuronal activation and cerebral flow of blood . Blood flow  increases in the active area of the brain.

In case of John, what happens is the localization of negative sentiments to the right hemisphere of the brain and positive sentiments to the left hemisphere of the brain.

Since, music can be related to positive sentiments, so, the left hemisphere of John's brain was more active as told by the researchers.
