Up till the 1840s, gross dissection was the only method available to study the tracts and fascicles of the white matter of the human brain. This changed dramatically with the introduction by Stilling (1842, 1843, 1846) of the microscopy of serial sections and his demonstration of the discriminative power of this method. The decussation of the brachium conjunctivum (the superior cerebellar peduncle) (International Anatomical Terminology (1998)) originally was known as the horseshoe-shaped commissure of Wernekinck. The first use of this name and the first illustrations of this commissure date from a book by Wernekinck’s successor, Wilbrand (1840).Using gross dissection, he concluded that the commissure connects the dentate nucleus with the contralateral inferior olive. A few years later, Stilling (1846), using microscopy of serial sections through the human brain stem, illustrated the entire course of the brachium conjunctivum, its decussation,and its crossed ascending branch, up to the red nucleus. From his work, it became clear that Wernekinck and Wilbrand had included the central tegmental tract in their commissure, and that they had failed to identify its ascending branch.
直到 19 世纪 40 年代，大体解剖学仍然是研究人脑白质束和束板的唯一方法。这种情况随着 Stilling（1842 年、1843 年、1846 年）引入连续切片显微镜技术而发生了巨大变化，他展示了这种方法的辨别力。结合臂（小脑上脚）（国际解剖学命名法（1998 年））的交叉原本被称为 Wernekinck 的马蹄形连合。这个名称的首次使用和这个连合的首次插图可以追溯到 Wernekinck 的继任者 Wilbrand（1840 年）的一本书。他使用大体解剖学得出结论，连合将齿状核与对侧下橄榄核连接起来。几年后，Stilling（1846 年）使用连续切片显微镜观察人类脑干，描绘了整个结合臂的行程、交叉和交叉上升分支，直至红核。从他的工作中可以清楚地看出，Wernekinck 和 Wilbrand 已经将中央被盖束纳入他们的连合中，并且他们未能识别其上升分支。
