Central Representation of Electroacoustic Stimuli

人工耳蜗最初只提供给深度失聪的人，现在对听力严重残留的人来说是例行公事。虽然在同一只耳朵内植入人工耳蜗和助听器的刺激已经被证明可以改善言语理解，特别是在噪音中，并提高声音的审美质量，但几乎对这些好处背后的生理机制知之甚少。我们项目的广泛目标是通过测量语音在下丘和听觉皮质中通过强直轴诱发的神经活动模式来解决这一缺陷，并评估神经活动模式允许区分不同语音的程度。

Cochlear implantation, initially only provided to profoundly deaf individuals, is now routine in people with substantial residual hearing. Although stimulation via a cochlear implant and hearing aid in the same ear has been shown to improve speech understanding, particularly in noise, and to increase the aesthetic quality of sound, almost nothing is known about the physiological mechanisms underlying these benefits. The broad aim of our project is to address this deficiency by measuring the patterns of neural activity evoked by speech sounds across the tonotopic axis in the inferior colliculus and auditory cortex and assess the extent to which the pattern of neural activity allows discrimination between the different speech sounds.
