Neural dynamics of mindfulness meditation and hypnosis explored with intracranial EEG: a feasibility study.

Intracranial electroencephalography (iEEG) can be used to compare brain activity during mind wandering, mindfulness meditation, and hypnosis. In three patients new to meditation and hypnosis, widespread amplitude modulations were common across all three states, especially in low-frequency bands (delta, theta, alpha) with positively correlated activity. Unique connectivity patterns for each state predominated in the gamma band, where about one-third of correlations were negative. The findings suggest iEEG is feasible for directly comparing these states and that gamma-band activity warrants further investigation.
