Abstract Mindfulness training (MT) and progressive muscle relaxation (PMR) are widely used stress-reduction practices, yet their neurochemical specificity remains almost unexplored. In a randomized, pre–post study, 30 healthy right-handed female speech-language therapy students were assigned to six weeks of MT or PMR. Short-echo time single-voxel H 1 -MRS (3T PRESS, TE ≈ 35 ms) and structural...
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. MRI studies investigating MM and hypnosis...
Nitrous oxide (N2O) has recently emerged as a potential fast-acting antidepressant but the cerebral mechanisms involved in this effect remain speculative. We hypothesized that the antidepressant response to an Equimolar Mixture of Oxygen and Nitrous Oxide (EMONO) would be associated with changes in cerebral connectivity and brain tissue pulsations (BTP). Thirty participants (20 with a major...
