核心B：信号处理和数据分析-摘要 信号处理和数据分析(SP&DA)核心支持增强功能和新开发 在PPG实验室内，并促进组成该PPG的项目之间的合作。《核心》 为三个项目(和相关实验室)中的每个项目提供服务，而不是单个PI可以获得的服务 通过单个项目，并通过共享专业知识和集中劳动力来提高效率- 密集的任务。此类资源的可获得性提高了 并使我们能够进行合作研究，否则将不会是 有可能。第一个具体目标是为各个实验室提供定制的硬件援助 参与三个项目；升级和维护刺激生成和实时数据采集 以及设计和制造PPG实验室使用的专用设备。第二个具体目标 是通过提供跨实验室/项目的交叉 实验室编程支持数据采集、刺激产生、信号和图像处理、数据 分析并支持PPG中所有实验室和参与者之间的沟通、共享和培训， 以及跨项目。第三个具体目标是为复杂的统计实验提供支持 设计和分析在所有三个项目中获得的建模数据，并大大提高我们的 了解由于听力/认知训练而导致的神经可塑性随年龄增长的改善情况。

CORE B: Signal Processing and Data Analysis - Abstract The Signal Processing and Data Analysis (SP&DA) core supports enhancements and new developments within PPG laboratories and facilitates collaboration among the projects that comprise this PPG. The Core provides services to each of the three projects (and associated labs) beyond what is available to individual PIs through the individual projects and increases effectiveness by sharing expertise and centralizing labor- intensive tasks. The availability of such resources increases the efficiency, sophistication, and innovation of the individual projects and enables us to pursue collaborative research efforts that would not otherwise be possible. The first specific aim is to provide customized hardware assistance to the individual laboratories participating in the three projects; upgrade and maintain stimulus generation and real-time data acquisition systems; and design and fabricate specialized equipment for use in PPG laboratories. The second specific aim is to facilitate and enable opportunities for collaboration across laboratories/projects by providing cross- laboratory programming support for data acquisition, stimulus generation, signal and image processing, data analysis, and support communication, sharing, and training across all laboratories and participants in the PPG, and across projects. The third specific aim is to provide support for sophisticated statistical experimental design and analysis for modeling data obtained across all three projects and substantially advance our knowledge of improvements in neuroplasticity with aging as a result of auditory/cognitive training.
