Unexpected EEG Patterns During Deep Meditation

This study recorded EEGs from 29 experienced Buddhist meditators practicing Jhāna, revealing unprecedented brainwave patterns: spindles, infraslow waves (ISWs), and spike-wave bursts. These patterns correlated with deeper meditative states, suggesting a progressive detachment from default sensory consciousness, aligning with stages of Buddhist Jhāna practice. The findings offer a novel perspective on the neural correlates of consciousness and raise questions about the intricate relationship between deep meditation and brain activity.
