不仅有证据表明女性和男性听众在声音感知方面存在行为差异，而且最近还提出了性别之间神经相关性差异的建议。fMRI功能语音定位器（包括一个单变量分析对比刺激与声乐与非声乐的声音）是已知的时间语音区（TVA）的鲁棒估计。然而，对fMRI数据采用多变量分析方法的兴趣越来越大（例如，多变量模式分析; MVPA）。本研究的目的是定位女性和男性听众的语音相关区域，并调查大脑地图是否会因听众的性别而有所不同。在单因素分析后，对女性（n = 149）和男性（n = 123）听众进行随机效应分析，并计算他们之间的对比。此外，采用全脑探照灯方法实施MVPA，并使用统计非参数映射（SnPM; Nichols和Holmes）将分类图输入基于二级排列的随机效应模型。性别差异仅见于MVPA。识别的区域位于颞中回（双侧）和颞中上级回（右半球）的中部。我们的研究结果表明，性别之间的分类器性能的差异，在响应的语音定位器具有较高的分类精度，从本地BOLD信号模式在几个颞叶区域的女性听众。
There is not only evidence for behavioral differences in voice perception between female and male listeners, but also recent suggestions for differences in neural correlates between genders. The fMRI functional voice localizer (comprising a univariate analysis contrasting stimulation with vocal vs. non-vocal sounds) is known to give robust estimates of the temporal voice areas (TVAs). However, there is growing interest in employing multivariate analysis approaches to fMRI data (e.g., multivariate pattern analysis; MVPA). The aim of the current study was to localize voice-related areas in both female and male listeners and to investigate whether brain maps may differ depending on the gender of the listener. After a univariate analysis, a random effects analysis was performed on female (n = 149) and male (n = 123) listeners and contrasts between them were computed. In addition, MVPA with a whole-brain searchlight approach was implemented and classification maps were entered into a second-level permutation based random effects models using statistical non-parametric mapping (SnPM; Nichols and Holmes,). Gender differences were found only in the MVPA. Identified regions were located in the middle part of the middle temporal gyrus (bilateral) and the middle superior temporal gyrus (right hemisphere). Our results suggest differences in classifier performance between genders in response to the voice localizer with higher classification accuracy from local BOLD signal patterns in several temporal-lobe regions in female listeners.
