Using techniques for enhanced microtubular preservation, including albumin pretreatment (Gray, 1975), occipital cortex of rats was studied electron microscopically at various ages of development. A close structural relationship was seen between microtubules, sacs of SER and the postsynaptic "thickening" in primordial spines and with the dense "plate" material of spine apparatuses. Stereoscopic preparations in addition show a more complicated substructure than previously described for the "plate". Microtubules may contribute to the formation of the "plate" of the spine apparatus which in turn is associated with the postsynaptic "thickening" of the mature spine. Possible functional correlates are discussed.
运用包括白蛋白预处理（格雷，1975年）在内的增强微管保存技术，对不同发育阶段大鼠的枕叶皮质进行了电子显微镜研究。在原始棘突中的微管、滑面内质网囊泡与突触后“增厚”之间以及与棘器的致密“板”状物质之间，观察到了紧密的结构关系。立体标本还显示出比先前描述的“板”更为复杂的亚结构。微管可能有助于棘器“板”的形成，而棘器又与成熟棘突的突触后“增厚”相关。文中讨论了可能的功能关联。
