Peculiarities of topography, structure and length of sulci and gyri in left and right hemisphere frontal areas were studied in newborns. Peculiarities of cytoarchitectonics of speech areas 44 and 45 were described in left and right hemisphere of neonatal brain. Differences in the extent of neuron radial orientation and thickness of the cortex especially of layer III were defined. Great variability in square of areas 44 and 45 in left and right hemisphere of neonatal brain was established. A hypothesis on formation of structural asymmetry of the Broca center and its areas 44 and 45 by the moment of birth and heterochronia of these fields development in ontogenesis is discussed.
研究了新生儿左右半球额叶区域脑沟和脑回的形态、结构及长度特点。描述了新生儿脑左右半球语言区44和45的细胞构筑特点。明确了神经元放射状排列程度及皮质尤其是第III层厚度的差异。确定了新生儿脑左右半球44和45区面积的巨大变异性。讨论了关于出生时布罗卡中枢及其44和45区结构不对称形成以及这些区域在个体发育中发育不同步的假说。
