③美国加利福尼亚大学的研究人员把两只全黑小猫饲养在一个园顶的天象馆似的黑暗环境中,从一出生就不让它们看见线条或有线性轮廓的物体,而只能看见分散的光点。这些光点看起来就象布满在夜空巾闪闪发光的星星,过一段时间对这种从未见过条线的猫进行生理研究,发现它们的视皮层细胞显著异常:它们只对很小的、移动的光点产生有选择的反应,只有很少的细胞似乎对物体的边缘还比较敏感,而且其中只有两个细胞接近那种对延展的刺
(3) Researchers at the University of California, Los Angeles, kept two all-black kittens in a park-like planetarium-like darkness from the moment they were born so that they could not see lines or linear silhouettes of objects but could only see scattered light spot. These spots looked like stars glittering in the night sky towel, and after some time studying the cats that had never seen the lines, they found that the visual cortex cells were significantly abnormal: they only worked for very small , Moving light spots produce a selective response, only a few cells seem to be more sensitive to the edges of the object, and only two of the cells are closer to the kind of extension to the spines
