Right visual field deficits in reaction time after invalid cues in chronic and never-medicated schizophrenics compared to normal controls

information processing dysfunction of schizophrenic (N = 70) versus patient controls (N = 20) and normal subjects (N = 50). Specifically, we will discuss schizophrenialinked changes in reactivity, sensorimotor gating, and habituation. These data are interpreted in conjunction with clinical state ratings (BPRS, SANS, SAPS), as well as with recent animal studies using PCP, MDMA, apomorphine, amphetamine, and antipsychotic medications. Cumulatively, these studies allow us to paint a fuller picture of the neurobiological substrate of schizophrenia and attentional abnormalities in the group of schizophrenias.
