Questions about blood flow

Functional magnetic resonance imaging (fMRI) is another highly utilized methodology for studying state changes in meditating brains. fMRI detects subtle increases in blood flow to areas of the brain with higher metabolic activity. Thus these areas of increased metabolic activity indicate which regions of the brain are currently being used to process whatever stimuli presented.

Studies have shown heightened activity in the anterior cingulate cortex, frontal cortex, and prefrontal cortex, specifically in the dorsal medial prefrontal area during Vipassana meditation.[8] Similarly, the cingulate cortex and frontal cortex areas were shown to have increased activity during Zen meditation.[9] Both studies comment on the possibility that these findings could indicate some state of heightened voluntary control over attention during mindfulness meditatio
