哺乳动物大脑和大脑皮层的几何形状从进化的角度进行了研究，并用数学术语进行了描述。与皮质表面积相反，大脑皮层的体积以类似的方式衡量大脑体积，与皮质折叠的程度无关。在哺乳动物中，鲸目动物是一个亚类，因为它们的体积数据比异速生长模型更符合等长模型。提出了一个皮质化指数，它包含了关于相互连接的神经纤维的质量和皮质内加工程度的信息。结果表明，半对数方程能较好地描述平均皮质厚度与脑体积之间的关系。最后，提出了脑体积和皮质参数之间的异速生长方程，可用于预测目的。
The geometry of the brain and cerebral cortex in mammals has been studied from an evolutionary perspective and is described in mathematical terms. The volume of the cerebral cortex, in contrast to the cortical surface area, scales to brain volume in a similar way, irrespective of the degree of cortical folding. Among mammals, Cetacea form a subgroup, in that their volumetric data fit an isometric model better than an allometric model. An index of corticalization is presented which contains information about both the mass of inter-connective nerve fibers and the degree of intracortical processing. It is shown, furthermore, that a semilogarithmic equation appropriately describes the relationship between mean cortical thickness and brain volume. Finally, allometric equations between brain volume and cortical parameters, which can be used for predictive purposes, are presented.
