The current study is concerned with the macroscopic and cytoarchitectonic structure of the motor speech area 44 in the left and right hemispheres of the brain of an outstanding writer (age 62 years). In a series of 20-μm frontal total paraffin sections stained with cresyl violet by the Nissl method, the density of total glia, the density of satellite glia, and the density of neurons surrounded by satellite glia were analyzed. The motor speech area of the cortex of the famous writer is characterized by a more complex macroscopic and cytoarchitectonic structure. In Broca's area, the density of total glia, satellite glia, and the neurons surrounded by satellite glia in associative layer III of area 44 were higher than in the control (brains of 5 men aged 59-71 years).
本研究关注的是一位杰出作家(62 岁)左右大脑运动言语区 44 的宏观和细胞构筑结构。在一系列经尼氏染色的 20μm 额部全石蜡切片中,分析了总神经胶质密度、卫星神经胶质密度和被卫星神经胶质包围的神经元密度。这位著名作家大脑皮质的运动言语区具有更为复杂的宏观和细胞构筑结构。在布罗卡区,与对照组(5 名 59-71 岁男性的大脑)相比,运动言语区 44 的第三层联合层中总神经胶质、卫星神经胶质和被卫星神经胶质包围的神经元的密度更高。
