正常志愿者（28名女性），年龄20-45岁，完成了视觉空间能力、语言流畅性和语言偏侧性的测试，并通过倒置恢复磁共振图像测量了胼胝体的脾、峡、中部和膝的正中矢状面面积。多变量统计用于分析相关模式。言语流畅性与脾的面积和主要由脾决定的后胼胝体因子的面积呈正相关。后胼胝体，尤其是脾，也与语言偏侧呈负相关。没有其他一致的大脑-行为关系。这些结果有助于理解表现出性别差异的认知特征发展的相关因素，以及理解语言偏侧化和言语能力的神经基础。
Normal volunteers (28 women), 20-45 years old, completed tests of visuospatial ability, verbal fluency, and language lateralization, and the midsagittal surface areas of the splenium, isthmus, midregion, and genu of the corpus callosum were measured from inversion recovery magnetic resonance images. Multivariate statistics were used to analyze patterns of correlations. Verbal fluency correlated positively with the area of the splenium and with the area of a posterior callosal factor defined largely by the splenium. The posterior callosum, particularly the splenium, also correlated negatively with language lateralization. There were no other consistent brain-behavior relationships. These results are relevant to understanding factors involved in the development of cognitive characteristics that show sex differences and to understanding the neural basis of language lateralization and verbal abilities.
