对人类听觉皮层功能组织的研究通常检查对不同声音类别的反应。另一种方法是关于声音在时域和频域中的变化量来表征声音（即，频谱和时间复杂度）。虽然绝大多数已发表的研究检查离散的声音类别之间的对比，一个替代的复杂性为基础的分类可以通过荟萃分析进行评估。在一项对58项听觉神经影像学研究的定量荟萃分析中，我们使用基于类别或频谱-时间复杂性的分组标准，研究了支持当前听觉处理功能专业化模型的证据。与目前的模型相一致，基于典型的声音类别的分析揭示了分层的听觉组织和左偏侧的语音声音的反应，在左前上级颞叶皮层的高语音敏感性。另一方面，基于频谱-时间复杂性的对比分类揭示了一种显著的半球内分离，其中听觉皮层的尾侧颞区对频谱变化表现出更大的敏感性，而前上级颞皮层区域对时间变化更敏感，这与最近在动物模型中的发现一致。因此，元分析表明，频谱-时间声学复杂性是一个有用的替代分类法，以调查人类听觉皮层的功能组织。
Investigations of the functional organization of human auditory cortex typically examine responses to different sound categories. An alternative approach is to characterize sounds with respect to their amount of variation in the time and frequency domains (i.e., spectral and temporal complexity). Although the vast majority of published studies examine contrasts between discrete sound categories, an alternative complexity-based taxonomy can be evaluated through meta-analysis. In a quantitative meta-analysis of 58 auditory neuroimaging studies, we examined the evidence supporting current models of functional specialization for auditory processing using grouping criteria based on either categories or spectro-temporal complexity. Consistent with current models, analyses based on typical sound categories revealed hierarchical auditory organization and left-lateralized responses to speech sounds, with high speech sensitivity in the left anterior superior temporal cortex. Classification of contrasts based on spectro-temporal complexity, on the other hand, revealed a striking within-hemisphere dissociation in which caudo-lateral temporal regions in auditory cortex showed greater sensitivity to spectral changes, while anterior superior temporal cortical areas were more sensitive to temporal variation, consistent with recent findings in animal models. The meta-analysis thus suggests that spectro-temporal acoustic complexity represents a useful alternative taxonomy to investigate the functional organization of human auditory cortex.
