在11只成年猫的单侧（或猫148的双侧）病变在mesodiencephalicjunction通过电凝。将这些动物的脑干横切成冷冻切片，根据Nauta-Gygax银技术6对其进行浸渍。由于上行变性纤维不能与小脑起源的纤维分开，因此只研究了下行变性纤维的分布。根据病变部位将动物分为3组，Ⅰ组5只。在猫109、114和124中，病变破坏了整个Cajal间质核（IS）和紧邻结构。在猫148 R和146中，病变破坏了IS的尾部和内侧纵束（MLF）的邻接部分。在所有这些动物中，观察到以下几组退化纤维。(a)有限数量的纤维穿过后连合，主要终止于对侧IS和对侧眼神经核和眼轮匝肌核（图1A中的1个）。这些纤维主要通过对侧MLF到达眼肌核。
In 11 adult cats unilateral (or bilateral in cat 148) lesions were made at the mesodiencephalicjunction by means of electrocoagulation. The brain stem of these animals was cut transversely in frozen sections, which were impregnated according to the Nauta-Gygax silver technique 6. Only the distribution of the descending degenerating fibers was studied since the ascending degenerating fibers could not be separated from the fibers of cerebellar origin. According to the lesion sites the animals were divided into 3 groups.Group I consisted of 5 cats. In cats 109, 114 and 124 the lesions destroyed the entire interstitial nucleus of Cajal (IS) and the immediately adjacent structures. In cats 148R and 146 the lesions destroyed the caudal part of the IS and the adjoining part of the medial longitudinal fasciculus (MLF). In all these animals the following groups of degenerating fibers were observed.(a) A limited number of fibers crossed through the posterior commissure to terminate primarily in the contralateral IS and in the contralateral oculomotor and trochlear nuclei (1 in Fig. IA). The fibers reached these eye muscle nuclei primarily by way of the contralateral MLF.
