Neuroelectrophysiological correlates of extended cessation of consciousness in advanced meditators: A multimodal EEG and MEG study

Extended cessation of consciousness in advanced meditators is linked to increased high-frequency global coherence across all five participants.

• Why it matters: Understanding the neural basis of EC can clarify how consciousness is modulated during advanced meditation, addressing gaps in knowledge about altered states of consciousness.
• What they did: Five meditators underwent simultaneous EEG and MEG recordings, revealing that EC significantly elevates high-frequency global coherence but does not consistently change Lempel-Ziv complexity or power.
• The result: Findings suggest EC involves neural reorganization of consciousness-related dynamics rather than a simple shutdown, offering insights into the neural signatures of advanced meditative states.
