在这篇综述中，我们将讨论一些神经策略的声音定位和编码耳间时间差（ITDs）在三个捕食性物种的爬行动物，鳄鱼，仓鸮和壁虎。鸟类和鳄鱼是现存的主龙类中的姐妹群，而壁虎是鳞龙类。尽管它们的听觉系统有着相似的组织结构，但祖龙和蜥蜴使用不同的策略来编码ITD，ITD是声音在方位角定位的基础。仓鸮使用位置图编码ITD信息，该位置图由神经元组成，这些神经元用作针对优选空间位置调整的标记线，而壁虎可能使用仪表策略，或由广泛敏感的神经元组成的种群代码，这些神经元通过放电率的变化来表示ITD。
In this review we will discuss some of the neural strategies for sound localization and encoding interaural time differences (ITDs) in three predatory species of Reptilia, alligators, barn owls and geckos. Birds and crocodilians are sister groups among the extant archosaurs, while geckos are lepidosaurs. Despite the similar organization of their auditory systems, archosaurs and lizards use different strategies for encoding the ITDs that underlie localization of sound in azimuth. Barn owls encode ITD information using a place map, composed of neurons serving as labeled lines tuned for preferred spatial locations, while geckos may use a meter strategy, or population code composed of broadly sensitive neurons that represent ITD via changes in firing rate.
