The results from the research suggest that a person who experiences auditory hallucinations that are localized in the expressive area of the brain is actually listening to his or her own thoughts. Since the problem is in the expressive area, this shows that the patient is only listening to the ideas his brain is already producing.
I cant the options but I'd say The Peripheral Nervous System (in the motor division which is separated into somatic motor nerves and autonomic motor nerves).
