Only a small number of studies investigated the correlation between the amount of brain activity and the amount of SA. Recent neuroimaging studies identified several areas (ventral premotor cortex, supplementary motor area, cerebellum, dorsolateral prefrontal cortex, posterior parietal cortex, posterior segment of the superior temporal sulcus, insula, and extrastriate body area, particularly in the right hemisphere) relating to SA. Researchers have tried to measure SA in human voluntary behavior, including various neurological and psychiatric diseases. Patients with these disorders deny their actions are voluntary. For example, patients with involuntary movement disorders do not feel SA, but acknowledge their body is moving (intact sense of ownership).ĭisturbances of SA arise in many neurological and mental disorders such as alien limb syndrome, psychogenic movement disorders, and schizophrenia. The sense of ownership is a different concept, the sense that I am the one who is undergoing an experience. The sense of agency derives from the proper match of volition and movement feedback. It is an essential component of voluntary movement allowing us to feel that we own our actions and that our actions are voluntary. SA is associated with the effect-related aspect of free will. It includes a spontaneous feeling that “self” is distinguished from “others” in the outside world during action generation. Sense of agency, specifically self-agency (SA), is the sense that “I am the one who is causing or generating an action.”.
