Question

Quizplus · Accepted Answer

The MRI scans showed that cortical thickness was positively correlated with meditation experience, indicating that the more someone practiced meditation, the thicker their cortex became in certain areas of the brain. This suggests that meditation may have a positive impact on brain structure and function. Option B and C are incorrect as they state the opposite findings. Option D is incorrect because studies have found differences between meditators and nonmeditators in brain structure and function.
