Clinical Trial Summary

The aim of the investigators project is to explore the mechanisms of pain insensitivity in patients with schizophrenia, in order to prevent its invalidating consequences. The investigators will couple methods of experimental psychology with EEG and blood samplings, in order to distinguish the role of non-painful perception, attention, aversive effects, and pain expression, and the investigators will explore an original neurobiological hypothesis regarding the activation of opioid receptors.
