DESCRIPTION: The applicant's long range goal is to contribute to understanding signal processing in the vertebrate ear. His approach is comparative, involving mammalian and amphibian subjects and involving five inner ear organs--including auditory sensors, vibratory sensors, and an equilibrium sensor. It is also integrative. He hopes to continue the top-down perspective needed to understand the mechanics of hearing and vestibular sensing. For the proposed project period, he plans to continue research in two areas, one experimental, one theoretical: (1) Adjustment of tuning and sensitivity in auditory, vibratory, and equilibrium sensors in response to changing ambient stimulus levels (2) Natural spectrograms and the role of axonal spike triggering in multiaxonal representations of temporal events in auditory and vibratory stimuli.

描述：申请人的远程目标是为 了解脊椎动物耳朵中的信号处理。 他的方法是 比较，涉及哺乳动物和两栖动物，涉及五个 内耳器官 - 包括听觉传感器，振动传感器和一个 平衡传感器。 它也是综合的。 他希望继续 自上而下的观点需要了解听力和 前庭感应。 在拟议的项目期间，他计划继续 在两个领域的研究，一个实验，一个理论：（1）调整 在听觉，振动和平衡传感器中的调整和灵敏度 对不断变化的环境刺激水平（2）自然光谱图和反应 轴突尖峰触发在多轴突表示中的作用 听觉和振动刺激中的时间事件。
