TLDR
It is suggested that the increased saccades seen during eye tracking and in other experimental conditions in schizophrenics are related to a deficit of nonvoluntary attention, due to a failure of an inhibitory mechanism.About:

Saccadic system functioning among schizophrenia patients and their first-degree biological relatives.
TL;DR: Results are consistent with the notion that dysfunction of dorsolateral prefrontal cortex, caudate nucleus, or both is related to liability for schizophrenia.

Abnormal ocular movements in Parkinson's disease. Evidence for involvement of dopaminergic systems.
Olivier Rascol,Michel Clanet,Jean-Louis Montastruc,M. Simonetta,M. J. Soulier-Esteve,B. Doyon,André Rascol +6 more
TL;DR: Results suggest a possible dopaminergic control of some ocular movements in patients with idiopathic Parkinson's disease without other associated neurological disease or dementia and Alterations of saccade latency and smooth pursuit peak velocity were more severe in the more advanced stages of the disease.
Journal ArticleDOI
Is eye movement dysfunction a biological marker for schizophrenia? A methodological review.
TL;DR: Findings in studies addressing the prevalence, stability, familial transmission, and psychological correlates of EMD in persons from both psychiatric and general populations offer suggestive evidence that this abnormality may serve as a biological marker for schizophrenia.
Journal ArticleDOI
Quantitative assessment of smooth pursuit gain and catch-up saccades in schizophrenia and affective disorders
TL;DR: The results indicate that the ocular motor systems of patients with schizophrenia and affective disorders process eye position error abnormally.
Journal ArticleDOI
Hypofrontality on topographic EEG in schizophrenia. Correlations with neuropsychological and psychopathological parameters.
TL;DR: Topographic EEG was performed in 17 DSM-III-R schizophrenic patients and in 15 sex- and agematched healthy controls to suggest abnormalities in these patients are of clinical and functional relevance, as they correlated significantly with psychopathological and neuropsychological parameters.

Eye-Tracking Patterns in Schizophrenia
TL;DR: A significant number of schizophrenic patients show patterns of smooth pursuitEye-tracking patterns that differ strikingly from the generally smooth eye-tracking seen in normals and in nonschizophrenic patients, which may have a critical relevance for perceptual dysfunction in schizophrenia.

Eye-tracking dysfunctions in schizophrenic patients and their relatives.
Philip S. Holzman,Leonard R. Proctor,Deborah L. Levy,N.J. Yasillo,Herbert Y. Meltzer,Stephen W. Hurt +5 more
TL;DR: The findings suggest proprioceptive and interoceptive involvement in schizophrenic pathology and the eye-tracking dysfunction may represent a genetic marker that can prove highly useful for studying the transmission of a vulnerability to schizophrenia.
Journal ArticleDOI
Frontal lobe dysfunctions in schizophrenia--I. Eye movement impairments.
TL;DR: The phenomena of eye movement impairments in schizophrenia are interpreted in this paper, Part I of a two-paper series, in the context of neural mechanisms of attention and eye movement control in terms of a dysfunction of temporo-parietal mechanisms of task-engagement.

Level of arousal and the subclassification of schizophrenia.
Peter H. Venables,J. K. Wing +1 more
TL;DR: The work to be described was designed to investigate further the relationships between arousal, withdrawal, and clinical condition.
Journal ArticleDOI
Smooth pursuit eye movements, attention, and schizophrenia.
TL;DR: The data indicate that nonvoluntary attending is specifically disordered in schizophrenics and their relatives, and implicate a neurophysiological substrate that can be described as a failure of inhibitory, synchronizing integrating systems which may be located in the brain stem.
