Despite the increasing popularity of mindfulness meditation and hypnosis in healthcare and in the general community the underlying neurobiological mechanisms are unclear. The change in the relationship between the self and the conscious experience that they bring about may be crucial. This study aims to identify the neural correlates of self-consciousness in meta-awareness and absorption - using functional Magnetic Resonance Imaging (fMRI) in healthy participants combined with detailed first-person experiential accounts and behavioural tasks. This study will provide important clues about the widely reported effects of mindfulness meditation and hypnosis and shed light on the neural correlates of the conscious experience of self.
