Altered effective connectivity within an oculomotor control network in individuals with schizophrenia

•Rapid control of planned gaze shift impaired in individuals with schizophrenia (SZ).•Current study aimed to investigate neural basis of these impairments.•SZ less efficient at inhibiting gaze shift, which was related to employment.•SZ showed altered activation in oculomotor control network during task performance.•Effective connectivity and its modulation by inhibitory demands altered in SZ.
