| Abstract/Results: | ABSTRACT:
The default mode network (DMN) has been largely studied by imaging, but not yet by neurodynamics, using EEG functional connectivity (FC). Mindfulness Meditation (MM), a receptive, non-elaborative training is theorized to lower DMN activity. We explored: 1) the usefulness of EEG-FC for investigating the DMN; and 2) the MM-induced EEG-FC effects. To this end, 3 MM groups were compared with controls, employing EEG-FC (mean phase coherence - MPC). Our results show that: 1) DMN activity was identified as reduced overall inter-hemispheric gamma MPC during the transition from resting state to a time production task; and 2) MM-induced a state increase in alpha MPC, as well as a trait decrease in EEG-FC. The MM-induced EEG-FC decrease was irrespective of expertise or band. Specifically, there was a relative reduction in right theta MPC, and left alpha and gamma MPC. The left gamma MPC was negatively correlated with MM expertise, possibly related to lower internal verbalization. The trait lower gamma MPC supports the notion of MM-induced reduction in DMN activity, related with self-reference and mind-wandering. This report emphasizes the possibility of studying the DMN using EEG-FC, as well as the importance of studying meditation in relation to it.
