GRK 591: Neurosensory Science and Systems: Measuring and Modelling the Processing of Sensory Information and its Applications

从眼睛、耳朵或触觉系统到其“内部表征”的感觉信息的处理将用多学科的方法进行调查、分析和建模。将考虑某些子系统的结构和功能(例如，视网膜中的神经网络)以及它们在明确定义的心理物理任务(例如，正常和听力受损的听者的响度感知)中各自的协作性能。特别强调对象知觉和对象表征的生理基础，其特征大概是不同感觉系统之间的相似性和相互作用。由于所采用的研究方法涵盖分子遗传学、单细胞电生理学、人类和动物心理物理学、脑电和脑磁图记录以及数值模拟，它们为功能成像技术提供了一个有效的参考框架，其中将特别考虑开发适当的、改进的范例。部分结果将用于临床和技术应用，如神经感觉任务中功能图像的改进解释，或通过采用基于听觉模型的处理技术来改进人机交流。申请人期望，通过神经生物学、心理物理学、数值模拟和信息技术驱动的算法开发之间的密切互动，可以在这一新的信息处理领域取得实质性进展。此外，在这一快速发展和令人着迷的领域培养高素质的年轻研究人员方面也做出了特殊贡献。

The processing of sensory information from the eye, ear, or tactilesystem into its "internal representation" will be investigated, analysed and modelled with a multidisciplinary approach. Both the structure and function of certain subsystems will be considered (e.g., neural networks in the retina) as well as their respective cooperative performance in well-defined psychophysical tasks (such as, e.g., loudness perception in normal and hearing-impaired listeners). Special emphasis is placed on object perception and the physiological basis of object representation which is presumably characterized by similarities and interactions across sensory systems. Since the research methods employed cover molecular genetics, single-cell electrophysiology, human and animal psychophysics, EEG and MEG recording, and numerical modelling, they provide a valid reference frame for functional imaging techniques where special consideration will be given on developing appropriate, improved paradigms. Parts of the results will be used for clinical and technical applications such as improved interpretation offunctional images in neurosensory tasks or improved man-machine-communication by employing auditory-model-based processingtechniques. The applicants expect that a substantial progress can be made in this new area of information processing by a close interaction between neurobiology, psychophysics, numerical modelling and information-technology-driven development of algorithms. Also, a special contribution is maintained to train highly qualified young researchers in this rapidly developing and fascinating field.
