视觉感知的神经机制

半个多世纪以前，Keffer H Hartline发表了他对青蛙单根视神经纤维的经典接受野研究。第二次世界大战介入，他的工作的全面影响直到50年代初才显现出来，当时霍勒斯·巴洛扩展了哈特兰在青蛙身上的分析，斯蒂芬·W·库弗勒展示了猫视网膜上的中心型和非中心型神经节细胞。下一个进展是在50年代后期，当时Jerome Lettvin和Humberto Maturana描述了青蛙顶盖中的细胞具有非常复杂的反应特性，而David Hubel和我发现猫的纹状皮层中的细胞对轮廓的方向和双眼刺激很敏感。从那时起，视觉研究已经走了很长一段路，尽管如此，我们才刚刚开始对视觉感知的神经基础进行详细的机械理解的漫长旅程。在这个讲座中，我将讨论在猫和猴子的纹状皮层层面上的视觉信息处理，并描述大大促进了视觉感知神经机制分析的技术进步。
It is more than half a century ago since Keffer H Hartline published his classical receptive fields studies of single optic nerve fibres in the frog. World War II intervened and the full impact of his work did not become apparent until the early fifties, when Horace Barlow extended Hartline's analysis in the frog and Stephen W Kuffler showed the on-centre and off-centre type ganglion cells in the cat retina. The next advances were made in the late fifties when Jerome Lettvin and Humberto Maturana described cells in the frog tectum with very complex response properties and when David Hubel and I discovered that cells in the cat striate cortex were sensitive to orientation of contours and binocular stimulation. Vision research has gone a long distance since that time—nonetheless we have just begun the long journey towards a detailed mechanistic understanding of the neural basis of visual perception. In this lecture I discuss the processing of visual information at the level of the striate cortex in the cat and monkey, and describe technical advances that have greatly facilitated the analysis of the neural mechanisms of visual perception.
