Author & Title: Andrew A. Fingelkurts, Alexander A. Fingelkurts and Tarja Kallio-Tamminen, Trait lasting alteration of the brain default mode network in experienced meditators and the experiential selfhood, Self and Identity, 2016, http://dx.doi.org/10.1080/15298868.2015.1136351
Abstract:
Based on the finding in novices that four months of meditation training significantly increases frontal default mode network (DMN) module/subnet synchrony while decreasing left and right posterior DMN modules synchrony, the current study tested the prediction whether experienced meditators (those who are practising meditation intensively for several years) had a change in the DMN “trinity” of modules as a baseline trait characteristic and whether this change is in a similar direction as in the novice trainees who practised meditation for only four months. Comparison of functional connectivity within DMN subnets (measured by electroencephalogram operational synchrony in the three separate DMN modules) between five experienced meditators and 10 naive participants (who were about to start the meditation training) fully support the prediction. Interpretation that links such DMN subnets changes to the threedimensional components of the experiential selfhood was proposed.
Keywords: Default mode network, DMN, subjective sense of self, first-person perspective, electroencephalogram, EEG, alpha rhythm, operational synchrony, functional connectivity, meditation, yoga, mindfulness.
