Corrélats neuronaux de la méditation de pleine conscience et de l'hypnose basés sur l'imagerie par résonance magnétique : similitudes et différences. Étude de la portée (scoping review). Republication
Abstract |
Background |
Mindfulness meditation (MM) and hypnosis practices are gaining interest in mental health, but their physiological mechanisms remain poorly understood. This study aimed to synthesize the functional, morphometric and metabolic changes associated with each practice using magnetic resonance imaging (MRI), and to identify their similarities and differences.
Methods |
MRI studies investigating MM and hypnosis in mental health, specifically stress, anxiety, and depression, were systematically screened following PRISMA guidelines from four research databases (PubMed, Web of Science, Embase, PsycINFO) between 2010 and 2022.
Results |
In total, 97 references met the inclusion criteria (84 for MM and 13 for hypnosis). This review showed common and divergent points regarding the regions involved and associated brain connectivity during MM practice and hypnosis. The primary commonality between mindfulness and hypnosis was decreased default mode network intrinsic activity and increased central executive network - salience network connectivity. Increased connectivity between the default mode network and the salience network was observed in meditative practice and mindfulness predisposition, but not in hypnosis.
Conclusions |
While MRI studies provide a better understanding of the neural basis of hypnosis and meditation, this review underscores the need for more rigorous studies.

• | The neural networks and regions modulated by mindfulness meditation and hypnosis showed similarities, differences, and various overlaps on MRI studies. |
• | The primary commonality between mindfulness and hypnosis was increased central executive network - Salience Network connectivity and decreased default mode network intrinsic activity. |
• | Increased connectivity between the default mode network and salience network was observed in meditative practice and mindfulness predisposition but not in hypnosis. |
• | Changes in brain morphometry after mindfulness meditation training are controversial. |
