Theravada Buddhist monks with extensive meditation experience underwent magnetoencephalography during focused attention meditation, open monitoring meditation, and resting states. Brain microstate coverage and occurrence differed between meditation and rest and between the two meditation styles. The Hurst exponent, a measure of long-range memory in brain dynamics, was lower during both meditation conditions than during rest. Lempel-Ziv complexity, which quantifies signal complexity, increased progressively from rest to focused attention meditation to open monitoring meditation. These changes in brain criticality indices suggest that meditation shifts brain dynamics toward a more critical state, paralleling changes in cognitive state.
