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)：这是一项支持两年一度的关于感觉编码和自然环境主题的国际会议的提案。感觉神经科学目前正在经历一场快速爆炸式的技术革命，这些技术使实验不再局限于使用受到高度简化刺激的固定动物。大量能够传输神经活动数据的可植入电极，成像技术的进步，在动物清醒和行为时使用光脉冲操纵神经元活动的可能性，以及在实验室模拟动态和响应环境的计算资源和技术，只是实验方法日益成熟的几个例子。这些方法允许在大脑在其自然环境中执行自然任务时直接观察和操纵大脑。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关联来优化它们的处理能力。另一方面，现实世界的复杂性带来了特殊的挑战，比如鸡尾酒会中的声源分离问题。因此，关键是要开发适当的方法来处理这种复杂性的输入/输出关系，并开发用于框架关于编码原则的预测的理论概念。这些方法和理论的进步是设计更好的助听器、感觉假体或其他技术(如使用计算机增强的虚拟环境)以解决感觉或沟通障碍的关键。因此，本次会议旨在召集一个跨学科的研究小组，他们具有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方面的专业知识，以讨论在自然环境和行为背景下感觉神经科学的研究前沿和新出现的共同原则和方法。 与公共健康相关：表征自然场景统计数据及其引发的复杂、适应性神经反应对于揭示神经信息处理策略以及推动神经假体的开发至关重要，这些假体能够将自然行为中遇到的声音和图像转换为大脑可以解释的格式。这个项目的目标是帮助资助一次跨学科会议，讨论关于这些主题的最新发现。
