31P MRS in the period of neuroactivation allows direct analysis of metabolic response on energy consuming processes. In this study we revealed decreased creatine kinase system response in visual cortex of early stage schizophrenia patients in the period of videostimulation: while PCr in normal activated cortex is reduced for ATP regeneration during activation, no PCr decrease was observed in patients. The data obtained allowed to offer a new neuronal metabolism scheme in response to stimulation at early stage of schizophrenia.
