一百多年来，大脑和身体尺寸的相互关系一直是研究的主题。这些研究表明，大脑重量的变化远小于体重的变化；因此，标度研究是负异速生长的研究。此外，当在物种之间而不是同一物种的个体之间进行比较时，大脑重量的变异性更大，并且不同目之间大脑大小的变异程度不同。在比较不同的个体发育阶段时，发现大脑尺寸相对于体重变化的最大变化。关于新陈代谢在确定脑-身体重量相互关系以解释相对大脑大小差异方面的重要性的争论仍在继续。尽管过去脑体尺寸关联研究的进展是通过增加数据库的大小和改进统计分析来实现的，但最近转基因动物的利用可能为这种关联的机制提供新的见解。
The interrelationship of brain and body sizes has been the subject of investigations for over a hundred years. These studies have demonstrated that variation in brain weights is much smaller than that in body weights; consequently, scaling studies are ones of negative allometry. Furthermore, the variability in brain weight is greater when comparisons are between species rather than among individuals of the same species, and the degree of variability in brain size differs among orders. The largest shifts in brain sizes relative to changes in body weights are found when comparing different ontogenetic stages. Debate continues as to the importance of metabolism in determining the interrelationship of brain-body weights for interpreting differences in relative brain size. Although past advances in the study of brain-body size associations have come by increasing the size of the data bases and by improved statistical analyses, the recent utilization of transgenic animals may provide new insights into the mechanism of this association.
