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.

该子项目的长期目标是影响我们 了解前庭处理和重要的功能之间的关系 认知处理方面，注意力。这些研究人员建议 前庭脊髓和前庭眼系统很大程度上是自动的，因此 当有足够的感官信息时，他们就没有注意力需求 可用于完整的系统。然而，他们相信，当感官 信息减少或退化 成功的注意力需求增加 整合前庭信息处理。三实验 建议协议。在所有实验中，患有外周疾病的患者 前庭病变将与年龄匹配和性别匹配一起研究 控制。在实验一和实验三中，研究人员将检查 不同姿势下不同条件下的前庭脊髓反应 挑战。在实验中要检查两个前庭眼反应 在表演的同时使用旋转前庭刺激 听觉反应定时任务。数据分析得到了很好的描述，使得 与该子项目中每个目标相关的具体假设相匹配 感兴趣的因变量和自变量。的物理资源 该子项目中描述的实验的实施已基本到位 这些研究人员已经并已成功使用。
