It is clear from the passage that Lustig's principal aim in conducting the study was ----.
Much work on aging brains has focused on their
failings, but a new study looks at how they succeed.
In a University of Michigan at Ann Arbor report on
which brain regions respond to challenging tasks,
researchers found that aging brains function
differently than young brains. Cindy Lustig of Ann
Arbor used functional magnetic resonance imaging to
observe the brains of young adults (aged 18 to 30)
and seniors (65 to 92) as they tackled simple and
difficult mental exercises. For the easy tasks, brain
activity was very similar, but tougher challenges
prompted differences. The seniors activated several
frontal brain regions that the young adults did not. In
addition, the younger people “turned off” parts of the
brain not used during the tasks, but the elders kept
those regions active. Lustig concludes that “older
adults' brains can indeed rise to the challenge, at
least in some situations, but they may do so
differently”.
