Question

Using fMRI, researchers have determined that the switch to meditation involves increases and decreases in what parts of the brain?

Answer 1

Using functional MRI, researchers have discovered that meditation is associated with increased activity in the prefrontal cortex and decreased stress response, indicating a shift in brain function.

Step-by-step explanation:

Researchers using functional MRI (fMRI) have noted changes in brain activity related to the practice of meditation. The technique of fMRI allows scientists to measure changes in blood flow and, by extension, neural activity in different parts of the brain during various tasks, including meditation. During meditation, there is often an increase in activation of the prefrontal cortex, which is associated with higher-order cognitive functions and a decrease in the stress response. This switch in brain activity may also involve the calming of the sympathetic nervous system, which is part of the body's response to stress.
