小脑具有统一的细胞结构和微电路，但其细分的大小在脊椎动物中差异很大。这种可变性对解剖学家来说是一个挑战，他们试图将体型差异与特征行为的差异联系起来。在这里，我们回顾了Lodewijk Bolk对哺乳动物小脑的早期工作，并将他的观察与展开的啮齿动物小脑地图联系起来。我们进一步从鸟类小脑的比较解剖中获得了见解，发现大脑中的小脑扩大并不是整体大脑扩大的被动结果，而是与特定的行为有关。我们推测，对于一些啮齿动物(例如松鼠)、灵长类动物和一些大脑鸟类(乌鸦、鹦鹉和啄木鸟)来说，特别大的小脑要么与前肢控制(松鼠和灵长类动物)的精化有关，要么就鸟类的喙控制而言。对这种运动行为的详细描述，再加上视觉控制的增强，可能有助于培养这些动物的操纵技能。最后，我们回顾了哺乳动物小脑的联系，并表明一些实验证据表明小脑在运动反射调节和运动学习的感觉控制中具有重要功能。
The cerebellum has a uniform cellular structure and microcircuitry, but the size of its subdivisions varies greatly among vertebrates. This variability is a challenge to anatomists to attempt to relate size differences to differences in characteristic behaviour. Here we review the early work of Lodewijk Bolk on the mammalian cerebellum and relate his observations to unfolded maps of the rodent cerebella. We further take insights from the comparative anatomy of the bird cerebella and find that cerebellar enlargement in large brains is not a passive consequence of overall brain enlargement, but is related to specific behaviour. We speculate that for some rodents (e.g., squirrels), primates and some large-brained birds (crows, parrots and woodpeckers), specifically enlarged cerebella are associated with either the elaboration of forelimb control (squirrels and primates) or in the case of the birds with beak control. The elaboration of such motor behaviour combined with increased visual control could have helped to furnish manipulative skills in these animals. Finally, we review the connections of the mammalian cerebellum and show that several pieces of experimental evidence point to an important function of the cerebellum in sensory control of movement reflex adjustment, and motor learning.
