Using in vivo magnetic resonance morphometry we measured the posterior wall of the left and right posterior ascending portion of the Sylvian fissure, an inferior parietal area of the brain that we have termed the planum parietale. Among 106 right-handers (53 women and 53 men) and 35 left-handers (18 women and 17 men), handedness and gender exerted an interactive influence on planum parietale asymmetry; right-handed men and left-handed women showed particularly strong rightward asymmetry. There was no correlation between asymmetry of the planum parietale and that of the anatomically adjacent planum temporale, suggesting an independency of these two structural markers of brain laterality.
我们使用活体磁共振形态测量法测量了大脑外侧裂左右后升支的后壁，即我们称为顶叶平面的大脑顶叶下部区域。在106名右利手者（53名女性和53名男性）和35名左利手者（18名女性和17名男性）中，利手和性别对顶叶平面不对称性产生了交互影响；右利手男性和左利手女性表现出特别强烈的向右不对称。顶叶平面的不对称性与解剖学上相邻的颞叶平面的不对称性之间没有相关性，这表明大脑半球优势的这两个结构标记是独立的。
