Neural processing underlying visual attention has been thought to involve the parietal cortex, but its contribution to the process has not been clear. Studies have suggested the lateral intraparietal area (LIP) of the posterior parietal cortex is involved in visual attention based on the phenomenon of attentional enhancement of visual responses (Bisley and Goldberg, 2003, 81). Behaviorally important stimuli are more likely to invoke a response than those which are of lesser importance, and the enhanced response has been attributed to the stimulus itself. However, there are exceptions to this premise, such as when the parietal response is sometimes less to a valid stimulus than to an invalid stimulus, and the probabili

toms; relatives of schizophrenia patients who do not exhibit schizophrenia spectrum personality symptoms; persons who exhibit schizophrenia spectrum personality symptoms in the absence of a family history of psychotic illness; and persons who do not exhibit schizophrenia spectrum personality symptoms and do not have a family history of psychotic illness. Across these five groups, measures of neurophysiological and cognitive impairment most strongly associated with risk of schizophrenia are likely to show the same decreasing pattern. Results obtained so far suggest that smooth pursuit eye movement abnormalities, antisaccade performance, visual attention and verbal working memory follow this pattern. Thaker and Avila are currently examining the interrelations among these risk markers to see which are likely to represent independent genetic effects, and which have common underlying genetic mechanisms. The phenotypes which evolve can then be compared to genetic studies which might lead to the identification of specific genes for schizophrenia, and might also provide more information about visual attention and eye movements and how they are related to this disorder. This will add to the knowledge of the mechanisms of eye move
