Changes in the brain induced by an eight-week meditation program, such as MBSR. A. coronal section; B. sagittal section; C. transverse section; D. composite view. Blue indicates the prefrontal cortex, associated with the immune system and resilience. Yellow indicates the hippocampus, associated with memory. The upper red region is the cingulate cortex, associated with emotional and impulse control and dealing with conflict. The lateral red regions are the insulae, which integrate bodily sensations and process internal sensations. The green indicates the amygdala, which governs emotions and regulates stress hormone secretion. Meditation training was shown to increase activity in the blue, yellow, and red regions and reduce activity in the green. Source: R. A.
