Different styles of meditation produce distinct patterns of brain activity and deactivation, according to a systematic review and meta-analysis of 78 functional neuroimaging studies. Four common styles—focused attention, mantra recitation, open monitoring, and compassion/loving-kindness—showed reliably dissociable activation patterns consistent with their psychological aims. Some brain areas, such as the insula and dorsal anterior cingulate cortex, were recruited across multiple techniques, but convergence was the exception. A preliminary effect-size analysis found medium effects for both activations and deactivations, suggesting potential practical significance. The review also raised methodological concerns and suggested avenues for future research.
