Transsaccadic Perception Deficits in Schizophrenia Reflect the Improper Internal Monitoring of Eye Movement Rather Than Abnormal Sensory Processing

Hyperactivation balances sensory processing deficits during mood induction in schizophrenia.

While impairments in emotion recognition are consistently reported in schizophrenia, there is some debate on the experience of emotion. Only few studies investigated neural correlates of emotional experience in schizophrenia. The present functional magnetic resonance imaging study compared a standard visual mood induction paradigm with an audiovisual method aimed at eliciting emotions more auto...

Visual sensory processing deficits in first-episode patients with Schizophrenia.

Evidence for sensory prediction deficits in schizophrenia.

OBJECTIVE Patients with schizophrenia experiencing delusions and hallucinations can misattribute their own actions to an external source. The authors test the hypothesis that patients with schizophrenia have defects in their ability to predict the sensory consequences of their actions. METHOD The authors measured sensory attenuation of self-produced stimuli by patients with schizophrenia and ...

Abnormal visuomotor processing in schizophrenia

Subtle disturbances of visual and motor function are known features of schizophrenia and can greatly impact quality of life; however, few studies investigate these abnormalities using simple visuomotor stimuli. In healthy people, electrophysiological data show that beta band oscillations in sensorimotor cortex decrease during movement execution (event-related beta desynchronisation (ERBD)), the...

Neurobiology of smooth pursuit eye movement deficits in schizophrenia: an fMRI study.

OBJECTIVE Smooth pursuit eye movements are abnormal in patients with schizophrenia. The investigators used functional magnetic resonance imaging (fMRI) to compare brain hemodynamic response during a smooth pursuit eye movement task in patients with schizophrenia and healthy comparison subjects. METHOD Fourteen patients with schizophrenia and 14 healthy comparison subjects performed a smooth p...
