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.

人工耳蜗植入最初只提供给重度聋人，现在已成为具有大量残余听力的人的常规手术。尽管通过人工耳蜗和助听器在同一只耳朵进行的刺激已被证明可以改善言语理解（尤其是在噪音中），并提高声音的美感，但人们对这些益处背后的生理机制几乎一无所知。我们项目的主要目标是通过测量下丘和听觉皮层中的音调轴上的语音引起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。
