科学家以蝙蝠为模式动物,从听觉、回声定位和生态适应与演化等方面开展了研究,取得了令人瞩目的成果。为适应回声定位,蝙蝠听觉系统的结构和功能产生了明显的特化。从外周到中枢形成了对声频率极为有序的表征,甚至在恒频- 调频(constant frequency-frequency modulation,CF-FM)蝙蝠耳蜗形成了所谓的听觉凹,以及听皮质功能组构也模块化,成为了具有代表性的特化象征。神经元反应的潜伏期对蝙蝠不仅是基本特性,也是回声定位行为调控的一部分;研究发现,有较长潜伏期的神经元具有较尖锐的回声-延迟调谐特性,而较短潜伏期的神经元则有较宽的回声-延迟调谐特性。蝙蝠听神经元对频率调谐的精准度亦远胜于...

Bats have been used as model animals to study their hearing, echolocation, ecological adaptation and evolution, and lots of remarkable results have been achieved. In order to adapt to echolocation, the structure and function of the auditory system in bats have developed distinct specializations. In the constant frequency-frequency modulation (CF-FM) bat cochlea, the so-called auditory fovea is formed, and the functional organization of auditory cortex is modular, which has become a representative specialized symbol. The latency of neuronal resp...
