最初由Hubel和Wiesel描述的成年猫视觉皮层神经元的特定定向特性，在正常饲养的小猫身上也观察到了2 -4。然而，在完全黑暗中饲养6周的小猫缺乏这些特性3 -5。英伯特和Buisseret 4在小猫中定义了三种类型的细胞，即特异性细胞、未成熟细胞和非特异性细胞。在黑暗饲养（DR）小猫，几个小时的视觉经验足以引起快速增加的比例定向特异性cells 3，5，6。我们在这里报告了一系列的实验进行，以确定参与的因素在'重建效应' 7的视觉经验的皮层特异性，并表明，oculerian探索，以及视觉输入，是一个必不可少的因素。
THE specific orientational properties of visual cortical neurones originally described by Hubel and Wiesel1in adult cats have also been observed in normally reared kittens2–4. Such properties are lacking, however, in kittens reared in complete darkness for six weeks3–5. Three types of cells, specific, immature and nonspecific, have been defined by Imbert and Buisseret4in kittens. In dark-reared (DR) kittens, a few hours of visual experience are sufficient to elicit a rapid increase in the proportion of orientation-specific cells3,5,6. We report here a series of experiments undertaken to determine the factors involved in the ‘reconstructive effect’7of visual experience for cortical specificity, and show that oculomotor exploration, as well as visual input, is an essential factor.
