Question

Quizplus · Accepted Answer

The study found that cortical thickness was positively correlated with meditation experience. This means that the more a person practiced meditation, the thicker their cortical regions were. This suggests that meditation may have a neuroprotective effect on the brain and may enhance cognitive function.

 The statement in option B is not supported by the study. The study found that several cortical areas were actually thicker in the meditators' brains than in the nonmeditators. Option C is also incorrect as the study did not find that meditators had less gray matter in regions associated with attention, emotion, and sensory processing.
