Understanding Temporal Integration of Time-varying Soun*

描述(由申请人提供)：拟议研究的长期目标是更好地了解听觉系统如何处理时变的刺激。拟议的研究将侧重于时变刺激的时间整合，这是一个相对较少受到关注的研究领域。这项拟议研究的总体目标有两个。首先是要了解时变刺激的哪些方面对时间整合是重要的。第一个目标的具体目标是测试：(1)调制周期的数量，而不是刺激持续时间，对于整合时间波动的刺激是重要的；以及(2)每个调制周期必须由听觉系统很好地分辨，才能用于时间整合。第二是更好地理解这种整合背后的处理类型。第二个目标的具体目标是：(1)测试听觉系统对来自每个调制周期的信息进行差异化加权；以及(2)然后组合该信息以增强对时间波动刺激的处理。

DESCRIPTION (provided by applicant): The long-term goal of the proposed research is to gain a better understanding of how the auditory system processes time-varying stimuli. The proposed research will focus on temporal integration of time-varying stimuli, an area of research that has received relatively little attention. There are two general goals of the proposed research. The first is to understand what aspects of time-varying stimuli are important for temporal integration. The specific aims of the first goal are to test: (1) that the number of modulation cycles, not the stimulus duration, is important for integrating temporally fluctuating stimuli; and (2) that each modulation cycle must be resolved well by the auditory system in order to be used for temporal integration. The second is to gain a better understanding of the type of processing underlying this integration. The specific aims of the second goal are to: (1) test that the auditory system differentially weights information from each modulation cycle; and (2) then combine that information to enhance the processing of temporally fluctuating stimuli.
