Neuronal oscillations present potential physiological substrates for brain operations that require temporal prediction. We review this idea in the context of auditory perception. Using speech as an exemplar, we illustrate how hierarchically organized oscillations can be used to parse and encode complex input streams. We then consider the motor system as a major source of rhythms (temporal priors) in auditory processing, that act in concert with attention to sharpen sensory representations and link them across areas. We discuss the circuits that could mediate this audio-motor interaction, notably the potential role of the somatosensory system. Finally, we reposition temporal predictions in the context of internal models, discussing how they interact with feature-based or spatial predictions. We argue that complementary predictions interact synergistically according to the organizational principles of each sensory system, forming multidimensional filters crucial to perception.
神经元振荡为需要时间预测的大脑操作提供了潜在的生理基础。我们在听觉感知的背景下审视这一观点。以语音为例,我们阐述了层次化组织的振荡如何用于解析和编码复杂的输入流。然后,我们将运动系统视为听觉处理中节律(时间先验)的主要来源,它与注意力协同作用,以锐化感觉表征并在不同区域之间建立联系。我们讨论了可能介导这种听觉 - 运动相互作用的神经回路,特别是体感系统的潜在作用。最后,我们在内部模型的背景下重新定位时间预测,讨论它们如何与基于特征或空间的预测相互作用。我们认为,互补预测根据每个感觉系统的组织原则协同相互作用,形成对感知至关重要的多维滤波器。
