In this description of the morphology of the mouse cerebellum, the main landmarks for subdivision were the discontinuities of the cortical sheet. In certain cerebellar sulci in the posterior lobe, the cortex is absent. Within the paramedian sulcus the cortex is interrupted rostral and caudal to the copula pyramidis. Rostrally, this discontinuity between vermis and hemisphere occupies a position corresponding to the intercrural sulcus of the ansiform lobule of other mammals. A subdivision into the simple lobule (VI and HVI), ansiform and paramedian lobule (HVII) and vermal lobule VII is proposed for this region, which accounts for the position of this cortexless area in the intercrural sulcus. Caudal to the copula pyramidis is the cortex is interrupted at the bottom of the paramedian sulcus between lobules X, IX and caudal VIII medially, and the paraflocculus and flocculus laterally. In most mammals, this area, devoid of cortex, extends much farther in the interparafloccular sulcus between the dorsal paraflocculus and the flocculus with the ventral paraflocculus. From the medullary surface of the cerebellar peduncles an area without cortex extends in between the ansiform lobule and the paraflocculus onto the copula pyramidis and the paramedian lobule. The nomenclature of the distal, foliated part of the paraflocculus in mouse, rat and rabbit is discussed.
在对小鼠小脑形态的描述中，用于细分的主要标志是皮质层的间断。在后叶的某些小脑沟中，皮质缺失。在旁正中沟内，皮质在锥体连合的头侧和尾侧中断。在头侧，蚓部和半球之间的这种间断占据了与其他哺乳动物袢状小叶的脚间沟相对应的位置。为此区域提出了分为简单小叶（VI和HVI）、袢状和旁正中小叶（HVII）以及蚓部小叶VII的划分，这解释了这个无皮质区域在脚间沟中的位置。在锥体连合的尾侧，皮质在旁正中沟底部中断，内侧在小叶X、IX和尾侧VIII之间，外侧在旁绒球和绒球之间。在大多数哺乳动物中，这个无皮质的区域在背侧旁绒球和绒球与腹侧旁绒球之间的旁绒球间沟中延伸得更远。从小脑脚的髓质表面起，一个无皮质的区域在袢状小叶和旁绒球之间延伸到锥体连合和旁正中小叶上。讨论了小鼠、大鼠和兔子中旁绒球远端叶状部分的命名法。
