摘要: This paper outlines a methodology to measure the ability of schizophrenic patient saccade against presented stimulus by tracking patient's electro- oculographic (EOG) activity. The overall goal is investigate deficit in this anti-saccade task as cognitive endophenotype for schizophrenia. A portable system performing test and novel biopotential amplifier are along with signal processing method analysis. Results based on control subjects indicate that mean performance above 89% achievable. study 5 patients indicates drops value 45%. be carried out Trinity College Neuropsychiatric Genetics Research Group currently assessing up 800 including schizophrenics their relatives.
