Researchers using PET or fMRI find that a certain brain area becomes highly active while people are frightened. Later they measure activity in that area for many people, and identify the people with the highest activity. What, if anything, can we conclude about those people based on this evidence?

We cannot draw any of these conclusions.

Explanation:

Useful, attractive reverberation imaging (fMRI) measures the little changes in the bloodstream that happen with mind movement. It might be utilized to analyze the cerebrum's useful life systems, figure out which parts of the mind are taking care of essential capacities, assess the impacts of stroke or other illness, or to guide cerebrum treatment.

FMRI may recognize variations from the norm inside the mind that cannot be found with different imaging strategies.
