A developmental comparison of the fields 8, 9, 10, 11, 12, 47 during prenatal life in macacus rhesus and man was performed. Cytomyeloarchitectonic and morphometric methods of investigation were applied: the areas of the fields in question, the transverse thickness of the cortex, separate cortical layers, neuronal dimentions were measured. Alongside, general regularities in the development of these fields in both species (the frontal cortex is laid earlier than other parts of the cortex, the terms of the field differentiation coincide, uneven development of the fields with different phylogenic origin) some important differences are demonstrated. They are seen a) in the rate of the frontal field maturation--in man it takes longer time, b) in a more complex organization of the frontal part in man--during prenatal life new structural features of the fields, 44, 45, 46 and subfields in the field 47 appear. During prenatal life of monkey and man in the development of the frontal area the phenomena of heterochrony (common for both species) and anabolia (peculiar for man only) are observed (the appearance of new more complex structures). These phenomena display themselves in the shift of the laying of the frontal area towards earlier stages of embryogenesis.
对恒河猴和人类孕期8、9、10、11、12、47区进行了发育比较。采用了细胞脊髓构筑学和形态测量学的研究方法：测量了相关脑区的面积、皮质的横向厚度、各皮质层以及神经元的尺寸。同时，在这两个物种中这些脑区发育的一般规律（额叶皮质比皮质的其他部分更早形成，脑区分化的时期一致，不同系统发生起源的脑区发育不均衡）之外，还发现了一些重要差异。这些差异表现为：a) 额叶成熟速度——人类所需时间更长；b) 人类额叶部分的组织更为复杂——在孕期出现了44、45、46区以及47区亚区的新结构特征。在猴和人的孕期额叶发育过程中，观察到了异时性现象（两个物种共有的）和变构现象（仅人类特有的）（新的更复杂结构的出现）。这些现象表现为额叶形成向胚胎发生早期阶段的推移。
