In this article, we studied individual features of the macroscopic structure of Broca's area of the brains in 9 women (18 hemispheres) aged from 20 to 30 years, without any mental or neurological disorders. By using MRI, the structures of the sulci and gyri of the pars triangularis and pars opercularis of Broca's area were studied: the anterior and ascending rami of the lateral sulcus, the radial, diagonal, precentral, inferior frontal, and lateral sulci. We also studied the relationship between the pars triangularis and pars opercularis as well as their relationships with neighboring cortical structures. We measured the volume of the pars triangularis and pars opercularis and the thickness of their cortex. Significant individual variability in the location and relationships between the anterior ramus of the lateral sulcus and the ascending ramus of the lateral sulcus, as well as structural features of the pars triangularis and pars opercularis of Broca's area were demonstrated.
在本文中，我们研究了 9 名年龄在 20 至 30 岁之间、无精神或神经障碍的女性（18 个大脑半球）的大脑布洛卡区的宏观结构的个体特征。通过 MRI，我们研究了布洛卡区三角部和盖部的脑回和脑沟的结构：外侧裂的前支和升支、放射状沟、斜角沟、中央前沟、额下回沟和外侧沟。我们还研究了三角部和盖部之间的关系以及它们与邻近皮质结构的关系。我们测量了三角部和盖部的体积以及皮质的厚度。外侧裂前支和外侧裂升支的位置以及它们之间的关系以及布洛卡区三角部和盖部的结构特征存在显著的个体差异。
