摘要

双侧人工耳蜗(BiCIs)可带来多种益处,包括改善噪音中的语音理解和声源定位。然而,双侧植入体给受助者带来的益处却因人而异。在此,我们将考虑造成这种差异的原因之一:双耳听力功能的差异,即耳间不对称。迄今为止,对耳间不对称的研究在不同的研究领域都非常专业。本综述的目的是将这些研究整合在一起,激励未来在耳间不对称领域的研究。我们首先考虑的是自下而上的处理过程,其中双耳线索是通过左耳和右耳信号的激发-抑制来表示的,随声音在空间中的位置而变化,并由听觉脑干的外侧上橄榄来表示。然后,我们考虑通过预测编码进行自上而下的处理,即假定知觉源于基于上下文和先前感官经验的预期,由一系列层叠的皮层电路表示。内部感知模型会根据输入的感官信息进行维护和更新。我们希望,将生理学、行为学和建模研究结合在一起,将有助于弥补双耳听力领域的不足,并促进人们更清楚地了解耳间不对称对未来最佳患者干预研究的影响。

Review of Binaural Processing With Asymmetrical Hearing Outcomes in Patients With Bilateral Cochlear Implants.

Bilateral cochlear implants (BiCIs) result in several benefits, including improvements in speech understanding in noise and sound source localization. However, the benefit bilateral implants provide among recipients varies considerably across individuals. Here we consider one of the reasons for this variability: difference in hearing function between the two ears, that is, interaural asymmetry. Thus far, investigations of interaural asymmetry have been highly specialized within various research areas. The goal of this review is to integrate these studies in one place, motivating future research in the area of interaural asymmetry. We first consider bottom-up processing, where binaural cues are represented using excitation-inhibition of signals from the left ear and right ear, varying with the location of the sound in space, and represented by the lateral superior olive in the auditory brainstem. We then consider top-down processing via predictive coding, which assumes that perception stems from expectations based on context and prior sensory experience, represented by cascading series of cortical circuits. An internal, perceptual model is maintained and updated in light of incoming sensory input. Together, we hope that this amalgamation of physiological, behavioral, and modeling studies will help bridge gaps in the field of binaural hearing and promote a clearer understanding of the implications of interaural asymmetry for future research on optimal patient interventions.

期刊介绍: Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
