Illustration of cerebral modifications that occur during meditation. In people who meditate. cerebral amygdala activity is reduced. there is greater activity in the visual cortex. the prefrontal dorsolateral cortex and each cerebral sulcus. the frontal superior sulcus and the intraparietal sulcus. Activation of the brain areas such as the insula and anterior cingulate cortex is also stronger in those that meditate. Finally they also have increased activity in the somatosnsorial cortex.
