Internal Monitoring of Eye Movement in Schizophrenia

正常人和精神分裂症患者都被要求跟随跳跃的目标灯，同时监测他们的眼球运动。 目标灯被短暂显示，然后在任何眼球运动之前熄灭，即记住目标。 在一个任务中，一系列的灯光被显示出来，受试者被要求在黑暗中将他们的眼睛移动到记忆中的序列的位置。 通过这种方式，我们能够寻找精神分裂症患者空间位置更新缺陷的证据。 本研究于2010年9月获得IRB批准。 由于实验室软件和视频眼动仪的设备问题，迄今为止还没有招募到受试者。 这些问题已经得到解决，我们已经开始招募受试者。 迄今尚未取得任何结果。

Both normal and schizophrenic subjects are asked to follow jumping target lights as their eye movements are monitored. The target lights are shown for brief periods and then extinguished before any eye movements are made, i.e. remembered targets. In one task a sequence of lights are shown and subjects are asked to move their eyes to the locations of the remembered sequence in the dark. In this way we are able to look for evidence of a defect in spatial location updating in subjects with schizophrenia. This study was approved by the IRB in September 2010. No subjects have been recruited to date because of laboratory software and equipment problems with a video eye tracker. These problems have been addressed and we have begun recruiting subjects. No results have been obtained to date.
