Theatre performances. The MET project aims to develop a methodology for therapy through theatrical tools, with an effect at the neurochemical and neurocognitive levels. In collaboration with our partners, we use behavioral, electrophysiological, biochemical and imaging techniques, to determine how minimalist theatrical practices impact stress level and social closeness. The scientific hypothesis of the project is that theatre practices modulate neuronal activity and plasticity by controlling the secretion of the neuro-hormones oxytocin and cortisol, and by adjusting the activity of the immune system. We believe that via these physiological changes, theatre therapies could induce pro-social behaviours, reduce stress, and increase the overall well-being of individuals.
