Schizophrenic patients have abnormal sense of agency. The patients experiencing passivity phenomena believe their thoughts and actions to be those of external or alien entities. In this study, the authors propose method for simulating the cognitive deficit in schizophrenia whose data are comparable to the experimental data. We proposed the efferent copy activation and comparator inhibition model describes under-attribution and over-attribution in schizophrenic subjects. The output of this functional model is mapped onto the corresponding brain area based on Talairach atlas. The simulation results of this study well describe the experimental results of a schizophrenic cerebral pattern of activation.
