DESCRIPTION (provided by applicant): This is a proposal to support a biennial international meeting on the topic of Sensory Coding and the Natural Environment. Sensory neuroscience is currently undergoing a rapid explosion in technologies that enable experimentation that is no longer constrained to the use of immobilized animals subjected to highly simplified stimuli. Large numbers of implantable electrodes able to transmit data about neural activity, advances in imaging techniques, the possibility to manipulate neuronal activity using light impulses while animals are awake and behaving, and the computational resources and techniques to simulate dynamic and responsive environments in the laboratory are only a few examples of the emerging sophistication in experimental methods. These methods permit direct observation and manipulation of the brain as it performs natural tasks in its natural environment. On one hand, theoretical and experimental studies have shown that sensory systems are able to exploit the complex correlations found in natural sounds and scenes to optimize their processing capacity. On the other hand, the complexity of the "real world" poses particular challenges, such as the sound source separation in the cocktail party problem. It is therefore critical to develop appropriate methods for handling input/output relationships of this complexity and to develop theoretical concepts that frame predictions about coding principles. These methodological and theoretical advances are key to the design of better hearing aids, sensory prosthetics or other technologies (such as the use of computer enhanced virtual environments) to address sensory or communicative disorders. This meeting therefore aims to bring together an interdisciplinary group of researchers with expertise in systems and cognitive neuroscience, perceptual psychology, statistics, signal processing, computer science and sensory aids to discuss the forefronts of research and emerging common principles and methods in sensory neuroscience in the context of natural environments and behavior. PUBLIC HEALTH RELEVANCE: Characterizing natural scene statistics and the complex, adaptive neural responses they elicit is essential for shedding light on neural information processing strategies, as well as for advancing the development of neural prostheses capable of transforming sounds and images encountered during natural behavior into a format interpretable by the brain. The goal of this project is to help fund an interdisciplinary meeting to discuss the latest findings on these topics.

描述（由申请人提供）：这是一项支持有关感官编码和自然环境主题的两年期国际会议的建议。 感觉神经科学目前正在技术中迅速爆炸，这使得不再限制使用受到高度简化刺激的固定动物的实验。大量能够传输有关神经活动的数据，成像技术的进步，使用明亮的脉冲在动物清醒和行为表现时操纵神经元活动的可能性以及在实验性方法中模拟动态和响应性环境的计算资源和技术的可能性仅是实验方法中出现成熟方法的少数示例。这些方法可以直接观察和操纵大脑，因为它在自然环境中执行自然任务。一方面，理论和实验研究表明，感觉系统能够利用自然声音和场景中发现的复杂相关性，以优化其处理能力。 另一方面，“现实世界”的复杂性提出了特定的挑战，例如鸡尾酒会问题中的声源分离。 因此，开发适当的方法来处理这种复杂性的输入/输出关系并开发出关于编码原理预测的理论概念，这一点至关重要。这些方法论和理论进步是设计更好的助听器，感觉假肢或其他技术（例如使用计算机增强的虚拟环境）来解决感觉或交流障碍的关键。 因此，这次会议的目的是将一个跨学科的研究人员汇集在一起​​，这些研究人员在系统和认知神经科学，感知心理学，统计学，信号处理，计算机科学和感官辅助工具方面有专业知识，以讨论在自然环境和行为的背景下，讨论研究的最前沿，并在感觉神经科学领域出现了共同的原理和方法。 公共卫生相关性：表征自然场景统计以及它们引起的复杂，适应性的神经反应对于阐明神经信息处理策略以及推进能够将自然行为过程中遇到的声音和图像的神经假体发展成大脑的形式的神经假体的发展。该项目的目的是帮助资助跨学科会议，讨论有关这些主题的最新发现。
