Distinct Neurochemical Signature of Mindfulness and Progressive Muscle Relaxation in limbic regions: a randomized controlled MR spectroscopy study
Research Square November 13, 2025 Quentin Beaufort, Lucie Angel, Laurent Barantin et al. preprint
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...
