猫小脑前叶的爬行纤维触觉感受区具有形状的规律性，与它们在小脑皮质上的相对位置无关。形状规则可以表示为生成接受场形状的组合规则。面部和爪子的接受区都是一组被称为隔室的皮肤区域的联合。脸部感受野是由一个种子隔室和另一个隔室的并集以二元关系产生的，称为CF邻接性。PAW感受野以类似的迭代方式形成，其约束条件是在所有参与感受野的脚趾上包含解剖学上相同的区域。本文规定了既再现观察到的感受野又预测尚未观察到的感受野的组合规则。由于攀爬纤维触觉感受野之间的形状规律，组合规则可以用来预测触觉刺激反应的整体激活。
Climbing fiber tactile receptive fields in the anterior lobe of the cat's cerebellum are found to have regularities of shape, independent of their relative position on the cerebellar cortex. The shape regularities can be expressed as rules of combination that generate the receptive field shapes. Both face and paw receptive fields are unions of a certain set of skin areas called compartments. Face receptive fields are generated by taking the union of a seed compartment and another compartment in a binary relation to it, called CF-contiguity. Paw receptive fields are formed in a similar iterative fashion, with the constraint that anatomically equivalent areas be included on all toes involved in the receptive field.This paper specifies rules of combination that both reproduce observed receptive fields and also predict receptive fields that have not yet been observed. Because of the regularities of shape among the climbing fiber tactile receptive fields, the rules of combination can be used to predict ensemble activation in response to tactile stimulation.
