精确的时间编码是听觉系统的标志。选择性的压力，以提高准确性或编码更快的变化产生了一套收敛的生理和形态特征，有助于时间编码。时间编码的比较研究还指出，共享的计算策略，并建议如何选择行为，以改善编码。鸟类耳蜗角核和哺乳动物耳蜗核具有异质性细胞群，对声音的反应相似。这些共享的特性可以表示对类似的选择性压力的会聚响应，以编码空气传播声音的特征。版权所有（C）2002 S. Karger AG，巴塞尔。
Precise temporal coding is a hallmark of the auditory system. Selective pressures to improve accuracy or encode more rapid changes have produced a suite of convergent physiological and morphological features that contribute to temporal coding. Comparative studies of temporal coding also point to shared computational strategies, and suggest how selection acts to improve coding. Both the avian cochlear nucleus angularis and the mammalian cochlear nuclei have heterogeneous cell populations, and similar responses to sound. These shared characteristics may represent convergent responses to similar selective pressures to encode features of airborne sound. Copyright (C) 2002 S. Karger AG, Basel.
