对131种灵长类动物、蝙蝠和食虫动物的数据分析表明，从脑髓质到前脑，大脑组成部分的大小可以通过非线性函数从绝对脑大小高度预测。研究发现，神经发生的顺序在许多哺乳动物中都是高度保守的，并且随着大脑大小的增加，神经发生的顺序与大脑结构的相对扩大有关，在大脑后期结构中出现不成比例的大增长。因为神经发生的顺序是保守的，任何行为能力的选择所导致的最可能的大脑改变可能是整个非嗅觉大脑的协调扩大。
Analysis of data collected on 131 species of primates, bats, and insectivores showed that the sizes of brain components, from medulla to forebrain, are highly predictable from absolute brain size by a nonlinear function. The order of neurogenesis was found to be highly conserved across a wide range of mammals and to correlate with the relative enlargement of structures as brain size increases, with disproportionately large growth occurring in late-generated structures. Because the order of neurogenesis is conserved, the most likely brain alteration resulting from selection for any behavioral ability may be a coordinated enlargement of the entire nonolfactory brain.
