Meditation May Push the Brain Toward an Optimal Balance of Chaos and Order

A small MEG study of 12 Theravada monk meditators finds two meditation methods shape brain activity differently: Samatha yields a stable, focused state, while Vipassana nudges the brain toward 'criticality'—an optimal balance between chaos and order that may enhance information processing and learning. Experienced meditators show brain activity closer to resting patterns, gamma oscillations can decrease (suggesting less external processing), and some practitioners report anxiety or other drawbacks. The findings contribute to understanding how meditation reshapes neural dynamics and were published in Neuroscience of Consciousness (2025).
