Central Representation of Electroacoustic Stimuli

耳蜗植入最初只提供给深度耳聋的人，现在在有大量残余听力的人中是常规的。虽然在同一只耳朵中通过人工耳蜗和助听器进行刺激已被证明可以提高语音理解，特别是在噪音中，并提高声音的美学质量，但几乎没有人知道这些好处背后的生理机制。我们的项目的广泛目标是解决这个缺陷，通过测量的语音引起的神经活动的模式，在下丘和听觉皮层的tonotopic轴，并评估在何种程度上的神经活动的模式允许不同的语音之间的歧视。

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.
