细胞色素氧化酶（C.O.）在幼猫出生后的第一个月，在外侧膝状体核的检查，并与成人的模式进行了比较。在第一周，大部分的C. O。位于膝状体神经元的胞体内。周膝状体神经元有反应性树突，以及perikaya。在第一周结束时，相对较大的暗反应神经元群体变得可分辨，因为大多数中型和小型神经元的反应水平降低到中度至轻度。根据它们的相对大小和分布模式，大多数暗反应神经元可能代表后来将具有1类形态并发展Y感受野特性的神经元。这些细胞通常较早经历快速生长，并且它们的生长比其他类别的反应性较低的膝状体神经元受到早期短期单眼缝合的不利影响。因此，在发育中的小猫的LGN中，C.O.组织化学可以用作未来1类Y细胞的功能标记。随着与树突的突触成熟，神经元的反应性逐渐增加。在电子显微镜水平上，神经元的反应性增加主要是由于位于生长树突内的反应性线粒体数量增加。
The distribution of cytochrome oxidase (C.O.) was examined in the lateral geniculate nucleus of the kitten during the first postnatal month and compared with the adult pattern. During the first week, most of the C.O. was localized within the perikarya of geniculate neurons. Perigeniculate neurons had darkly reactive dendrites as well as perikaya. A population of relatively large, darkly reactive neurons became distinguishable around the end of the first week, as the level of reactivity diminished to moderate‐to‐light within most medium and small neurons. On the basis of their relative size and pattern of distribution, most of the darkly reactive neurons are likely to represent ones that will later have class 1 morphology and develop Y receptive field properties. These cells normally undergo rapid growth earlier, and their growth is more adversely affected by early short‐term monocular suture than other classes of less reactive geniculate neurons. Thus, in the LGN of developing kitten, C.O. histochemistry may be used as a functional marker for future class 1 Y‐cells. The reactivity of the neuropil gradually increases as synapses with dendrites mature. At the electron‐microscopic level the increased reactivity of the neuropil is due mainly to an increase in the number of reactive mitochondria localized within the growing dendrites.
