2 - Description of the project methodology There is strong evidence for schizophrenia being a neuro-developmental disorder (Rapoport et al., 2005). It has been shown, for many years, that patients with schizophrenia exhibit abnormal patterns of sensorimotor integration (Manschreck et al., 1982), which is the capacity to integrate different sensory stimuli into appropriate motor actions. It is clinically relevant, in terms of early diagnosis and prevention, whether deficient sensorimotor integration is present in the prodromal phase of schizophrenia, and whether this constitutes a vulnerability marker for the disease.
