Neural correlates of mindful self-awareness in mindfulness meditators and meditation-naïve subjects revisited.
Biological Psychology September 1, 2016 J Lutz, A B Brühl, H Scheerer et al.
Mindful self-awareness, a core component of mindfulness meditation, is linked to reduced activity in brain regions involved in self-referential thinking (cortical midline structures) and emotion (amygdala), alongside increased activity in somatosensory areas. Using fMRI, experienced meditators (average 4,652 practice hours) and meditation-naïve participants engaged in short periods of mindful self-awareness and self-referential thinking. Both groups showed somatosensory activation and decreased cortical midline activity during mindful awareness, but experienced meditators exhibited significantly stronger decreases in prefrontal midline regions and reduced activity in language-related areas. Higher amygdala and midline activity during mindful awareness correlated with depressiveness. Meditation training may reduce self-reference and verbalization during mindful awareness, supporting its role in healthy self-related neural functions.
