Neurofunctional assessment of schizophrenia: a preliminary investigation of the presence of eye-tracking (SPEMs) and quality extinction test (QET) abnormalities in a sample of schizophrenic patients.
This preliminary study evaluated the simultaneous presence of abnormalities in the regulation of eye-tracking and neuropsychological tests performance (tactile extinction) in a sample of schizophrenic patients. Both those measures of central malfunctioning appears to be quite specific to schizophrenic disorders and more related to the trait, rather than state characteristics. Even though preliminary, the results indicate a significant relationship between abnormalities in SPEM regulation and the distribution of tactile abnormalities, with more left-side extinguishing patients showing abnormal SPEMs. Some interpretations of the findings are given in the context of current hypotheses on the neurofunctional abnormalities of schizophrenics.
