The planum temporale (PT) has been of interest because of (1) its consistent left greater than right asymmetry among right-handed and most left-handed normal individuals; and (2) its relation to language, another variable shown to be highly left-lateralized in normal subjects. Individuals with neurodevelopmental disorders have been reported to show abnormal PT asymmetry (either reversed or absent asymmetry). Several studies have been conducted measuring the PT on MRI scans, although the results do not always concur. We review some of these studies and discuss methodological differences between them. Additionally, we propose a method that has proved to be highly reliable for the measurement of both temporal PT and its parietal extension (PT+).
颞平面（PT）一直备受关注，原因如下：（1）在右利手和大多数左利手的正常个体中，其始终呈现出左大于右的不对称性；（2）它与语言相关，而语言是另一个在正常受试者中显示出高度左侧化的变量。据报道，患有神经发育障碍的个体表现出异常的PT不对称性（不对称性逆转或缺失）。已经进行了几项在MRI扫描上测量PT的研究，尽管结果并不总是一致。我们回顾其中一些研究，并讨论它们之间的方法学差异。此外，我们提出了一种方法，该方法已被证明在测量颞部PT及其顶叶延伸部分（PT+）时具有高度可靠性。
