To study the general patterns and differences in the macroscopic structure of Broca's motor speech area in the left and right hemispheres of male and female brains.
The study was conducted on MRI images of the brains of 9 men and 9 women (36 hemispheres in total). All the people were between the ages of 20 and 30, without any mental or neurological disorders. The localization and structure of the main sulci and gyri of Broca's area, namely the pars triangularis and pars opercularis, were studied. In addition, the topography of the main sulci in Broca's motor speech area, namely their shape, length, and relative position to the other sulci, was analyzed.
The features of the localization of the sulci in Broca's area, the differences in the number of additional sulci in the pars triangularis and pars opercularis of male and female brains, as well as the degree of asymmetry of Broca's area in the left and right hemispheres of the brains of men and women were established.In modern neuroscience a new scientific direction of genderology, which studies the behavior and cognitive functions of males and females, is rapidly developing.
Broca's motor speech area of the brain of men and women differs in macroscopic structure.
研究男性和女性大脑左右半球布洛卡运动性语言区宏观结构的一般模式及差异。
对9名男性和9名女性（共36个半球）的大脑MRI图像进行研究。所有受试者年龄在20至30岁之间，无任何精神或神经疾病。研究了布洛卡区主要脑沟和脑回（即三角部和岛盖部）的定位和结构。此外，分析了布洛卡运动性语言区主要脑沟的局部解剖学特征，即其形状、长度以及与其他脑沟的相对位置。
确定了布洛卡区脑沟的定位特征、男性和女性大脑三角部和岛盖部额外脑沟数量的差异，以及男性和女性大脑左右半球布洛卡区的不对称程度。在现代神经科学中，一个研究男性和女性行为及认知功能的新科学方向——性别学正在迅速发展。
男性和女性大脑的布洛卡运动性语言区在宏观结构上存在差异。
