The aim of this study was to assess the size of the corpus callosum in members of Mensa International, which is the world's largest and oldest high-intelligence quotient (IQ) society.
We performed T2-weighted magnetic resonance imaging (Repetition Time, TR = 3200 ms, Time of Echo, TE = 409 ms) to examine the brain of members of Mensa International (Polish national group) in order to assess the size of the corpus callosum. Results from 113 male MENSA members and 96 controls in the age range of 21-40 years were analyzed.
The comparative analysis showed that the mean length of the corpus callosum and the thickness of the isthmus were significantly greater in the Mensa members compared to the control groups. A statistically significant difference was also identified in the largest linear dimension of the brain from the frontal lobe to the occipital lobe. The mean corpus callosum cross-sectional area and its ratio to the brain area were significantly greater in the Mensa members.
The results show that the dimensions (linear measures and midsagittal cross-sectional surface area) of the corpus callosum were significantly greater in the group of Mensa members than in the controls.
本研究旨在评估门萨国际（Mensa International）成员的胼胝体大小，门萨国际是世界上最大和历史最悠久的高智商（IQ）协会。
我们对门萨国际（波兰国家组）成员的大脑进行了 T2 加权磁共振成像（重复时间，TR=3200ms，回波时间，TE=409ms），以评估胼胝体的大小。分析了 113 名年龄在 21-40 岁之间的男性门萨成员和 96 名对照组的结果。
对比分析表明，与对照组相比，门萨成员的胼胝体平均长度和峡部厚度明显更大。大脑从前额叶到枕叶的最大线性尺寸也存在统计学上的显著差异。门萨成员的胼胝体横截面积及其与大脑面积的比值明显更大。
结果表明，门萨成员的胼胝体尺寸（线性测量值和正中矢状面面积）明显大于对照组。
