库夫勒（1953）第一次系统地描述了猫视网膜上神经节细胞的感受野。他从细胞体上进行记录，他所研究的所有细胞的感受野都有两种组织方式：“中心上”细胞的感受野包含一个中心区域，在这个中心区域内，光照的增加导致脉冲放电的增加，被一个环形的低灵敏度周围区域包围，当光照时，会导致放电的减少，或者减少由感受野中心部分的光照引起的增加。在“偏离中心”的细胞中，灵敏度的极性是相反的，但除此之外，这两种类型的细胞似乎具有相似的特性。Hubel和Wiesel（1960）后来发现，蜘蛛猴的大部分视束纤维与猫的神经节细胞具有基本相同的感受野组织，尽管少数单位具有不同寻常的感受野。事后看来，感受野特性的一致性是令人惊讶的，因为神经节细胞的巨大形态多样性已被Cajal（1993）清楚地显示出来。所有这些多样性不太可能是提供互补细胞类型（在中心和离中心）所需要的，尽管其中一些可能是（Nelson et al., 1978）。也许值得指出的是，无论最终识别何种神经节细胞，在每一类中都可能识别互补亚型，或者特定类型的细胞对增量和减-的反应相同
BackgroundKuffler (1953) gave the first systematic description of the receptive fields of ganglion cells in the cat’s retina He recorded from cell bodies, and all those he studied had receptive fields organized in one of two ways: the receptive fields of “on-centre” cells contained a central region, within which increases in illumination caused an increased discharge of impulses, enclosed by an annular surrounding region of lower sensitivity that whenilluminated brought about a decrease in discharge, or reduced the increase that would have arisen from illumination of the central part of the receptive field. In “off-centre” cells the polarity of sensitivities was reversed but otherwise the two types of ceil seemed to have similar properties. Hubel and Wiesel (1960) later found that most optic tract fibres in the spider monkey had substantially the same receptive field organization as ganglion cells of the cat, although a few units had unusual receptive fields.The uniformity of receptive field properties is, with hindsight, surprising since the great morphological diversity of ganglion cells had been shown clearly by Cajal (l893). All this diversity is unlikely to be needed for the provision of complementary cell types (onand off-centre), although some of it might be (Nelson et al., 1978). It is perhaps worth pointing out that, whatever varieties of ganglion cells are ultimately recognized, complementary sub-types will probably be recognized in each class, or cells of a particular type will respond identically to incremental and dec-
