ATTENTIONAL INFLUENCES OF VESTIBULAR DISORDERS

这个子项目的长期目标是影响我们的 前庭加工与一个重要的 认知加工方面，注意力。这些调查人员提出， 前庭-脊柱和前庭-眼睛系统在很大程度上是自动的，因此 当有足够的感官信息时，它们不需要注意 对完整的系统可用。然而，他们认为，当感官 信息减少或降级注意力需求增加才能成功 前庭信息加工中的整合。三个实验性的 提出了相应的协议。在所有实验中，外周血患者 前庭病变将与年龄匹配和性别匹配一起进行研究 控制。在实验一和实验三中，研究人员将检查 不同后置状态下的前庭-脊髓反应 挑战。在实验中，要检查两个前庭-眼睛反应 在表演的同时使用旋转前庭刺激 听觉反应计时任务。数据分析被很好地描述为 与该子项目中的每个目标相关联的特定假设与 感兴趣的因变量和自变量。中国的物质资源 本子项目中描述的实验的实施已基本到位 已经并已被这些调查人员成功使用。

The long term objective of this subproject is to impact our understanding of the relationship between vestibular processing and an important aspect of cognitive processing, attention. These investigators propose that vestibulo-spinal and vestibulo-ocular systems are largely automatic, such that they are free of attentional demands when adequate sensory information is available to the intact system. However, they believe that when sensory information is reduced or degraded attentional demands increase for successful integration in processing of vestibular information. Three experimental protocols are suggested. In all experiments, patients with peripheral vestibular lesions will be studied along with age matched and gender matched controls. In experiments one and three the investigators will examine vestibulo-spinal responses under different conditions of varying postular challenge. In experiment two vestibulo-ocular responses are to be examined using rotational vestibular stimulation concurrent to the performance on an auditory reaction timed task. Data analyses are well described such that the specific hypotheses associated with each aim in this subproject are matched to dependent and independent variables of interest. The physical resources for the conduct for the experiments described in this subproject are largely in place already and have been successfully used by these investigators.
