在过去的十年中，对听觉系统的重新关注导致了灵长类动物听觉皮层及其目标的解剖学和生理学研究的激增。解剖学研究已经描绘了初级听觉皮层内部和周围的多个区域，并证明了这些区域之间的连通性，以及这些区域与其他皮层之间的连通性，包括前额叶皮层。听觉神经元的生理记录发现，物种特异性发声有助于探测听觉神经元的选择性和潜在功能。许多皮质区域包含对发声有强烈反应的神经元，一些听觉反应神经元对发声比对其他复杂声音有更多的选择性。发声选择性的证明提出了一个问题，即哪些特征是由高阶听觉神经元编码的。基于对这些发声结构的详细研究，以及对这些发声敏感的神经元的调谐和信息编码特性，已经开始为这个问题提供答案。在未来的研究中，这些方法和其他方法可能有助于确定细胞、集合和大脑区域处理交流声音的方式。此外，一些非初级听觉皮层区域可能是多感觉的，并对相应的面部手势的发声做出反应，这一发现可能会改变我们对听觉系统处理交流信息的看法。
Over the past decade, renewed interest in the auditory system has resulted in a surge of anatomical and physiological research in the primate auditory cortex and its targets. Anatomical studies have delineated multiple areas in and around primary auditory cortex and demonstrated connectivity among these areas, as well as between these areas and the rest of the cortex, including prefrontal cortex. Physiological recordings of auditory neurons have found that species-specific vocalizations are useful in probing the selectivity and potential functions of acoustic neurons. A number of cortical regions contain neurons that are robustly responsive to vocalizations, and some auditory responsive neurons show more selectivity for vocalizations than for other complex sounds. Demonstration of selectivity for vocalizations has prompted the question of which features are encoded by higher-order auditory neurons. Results based on detailed studies of the structure of these vocalizations, as well as the tuning and information-coding properties of neurons sensitive to these vocalizations, have begun to provide answers to this question. In future studies, these and other methods may help to define the way in which cells, ensembles, and brain regions process communication sounds. Moreover, the discovery that several nonprimary auditory cortical regions may be multisensory and responsive to vocalizations with corresponding facial gestures may change the way in which we view the processing of communication information by the auditory system.
