Although overactive inner speech has been one of the major theoretical accounts of auditory verbal hallucinations (AVHs) in schizophrenia, inner speech associated with the mental generation of thoughts has only been rarely examined. In this study, we present a follow-up experiment investigating the neural underpinnings of verbal thought generation and verbal auditory perception using fMRI. Constrained principal component analysis was used to identify networks of cerebral activation associated with generating thoughts and auditory perception.
