Different meditation practices—focused attention, open monitoring, and loving kindness—share a common brain connectivity pattern while also showing distinct neural signatures. Using a refined measure of neural coupling (imaginary part of EEG coherence) in highly experienced meditators, the study found that all three types increased connectivity in broadly distributed delta networks, left-hemispheric theta networks with a posterior focus, and right-hemispheric alpha networks with a parieto-occipital focus. Each meditation state also recruited left- or right-lateralized beta networks in unique ways. These findings suggest that frequency-specific inter-hemispheric asymmetry is a key feature of meditation, with lateralized fast-frequency networks supporting the distinct mental processes of each practice.
