本文报告了50例人大脑(100个大脑半球)表面某些沟回的测量值及观察结果。数据经电子计算机分析,相关有显著性的项目为:脑长与颞枕距;脑长与右中央沟;脑长与右缘上回;左半球的颞枕距与中央沟,颞枕距与外侧裂(后支)、角回与缘上回面积;两半球角回面积、两半球缘上回面积。中央前回最宽处相当于Penfield机能分区图的手及口区(发声部位);中央后回最宽处相当于该图的手指与舌感觉区。颞横回以3～4条类型多见(84±4％)。对3例脑组织切片镜检,见颞横回的前、中、后三条形态类似,属颗粒型皮质,各层只见小锥体细胞。
This article reports the measurements and observations of some dorsal gyrus on the surface of 50 human brains (100 hemispheres). The data were analyzed by electronic computer. The related significant items were: the length of the brain and the temporal pillow; the length of the brain and the right central ditch; the length of the head and the right edge of the brain; the temporal pitch of the left hemisphere and the central groove, Lateral fissure (posterior branch), angle gyrus and margin area; hemispherical angle area, hemispheric margin area. The width of the back of the center is equal to the hand and mouth area of Penfield’s function zoning map (vocal part); the widest back point of the center is equivalent to the finger and tongue sensing area of the figure. Temporal and transverse reversion in 3 to 4 types of more common (84 ± 4%). Three cases of brain tissue microscopy, see the temporal transverse cross-sectional similar to the former, middle and back three, is a granular cortical, all see only small pyramidal cells.
