摘要
国家自然科学基金重大项目“视觉信息加工”研究为期四年,由中国科学院生物物理研究所、生理研究所和中国科学技术大学生物系共同承担。项目内容包括中脑视觉神经回路中的信息加工,胼胝体传递视觉信息的特征,蜜蜂模式识别及平行加工机理研究,视觉信息加工中空间-时间相互作用及其神经机制的研究,视觉感受野空间相互作用与复杂图象的加工处理,视觉图象识别中眼动图象特征抽提作用的研究,和视觉信息处理中基本神经网络的算法理论描述等七个课题,现已圆满完成任务。研究者围绕着中枢视觉信息加工这一核心问题,应用多种技术,在神经回路、生理机制和理论模型等方面都取得了重要进展。本文简要介绍此项研究提出的背景,所取得的主要学术进展及其理论意义,以及作者的体会和建议。
A research project which receives a special grant from the NSFC has recently concluded fruitfuely. The four-year project, which was carried out by a group of neuroscientists from Institute of Biophysics and Institute of Physiology, Academia Sinica, and from Department of Biology, the Science and Technology University of China, consisted of seven subprojects, namely information processing in visual neural circuits of the midbrain of low vertebrates, characteristics and roles of signals conveyed by the visual callosal fibers, temporal-spacial interactions of visual information and the underlying mechanisms, spacial interaction of the receptive fields and the processing of complex patterns, characteristics of eye movements in reading recognition, and theoretical description of the algorithm used in neural networks. Using a number of different techniques and concentrating on central visual information processing, the investigators have made essential advances on clarifying neural circuits and physiological mechanisms, and on theoretical modeling. This article presents briefly the background of this project, the main scientific achievements and their significance, as well as, from the point of view of the author, some experience and suggestions.
