Recognizing the Sensory Consequences of One’s Own Actions and Delusions of Control
This chapter examines schizophrenia and agency. In schizophrenic patients there is a tendency to misattribute behaviors initiated by the self to an external agent. The chapter describes experimental examinations of this tendency, focusing especially on PET imaging during voluntary action. It suggests that two regions appear important for the sense of agency, specifically the cerebellum and the parietal cortex. Excessive activity of a cerebellar-parietal network results in misattribution of agency such that self-generated actions are thought to have an external origin.
