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刺激。拟议中的研究将集中在时变刺激的时间整合，一个研究领域，已收到相对较少的关注。拟议的研究有两个总目标。首先是了解时变刺激的哪些方面对时间整合很重要。第一个目标的具体目的是测试：（1）调制周期的数量，而不是刺激持续时间，对于整合时间波动刺激很重要;（2）每个调制周期必须由听觉系统很好地解析，以便用于时间整合。第二个目的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的是：（1）测试听觉系统对来自每个调制周期的信息进行差分加权;以及（2）然后联合收割机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.
