Recent literature on the Field L of songbirds, showing that some neurons present a clear selectivity towards complex sounds, especially conspecific songs, is reviewed. Furthermore, studies on European starlings have revealed a complex functional organization in this central auditory area, with subareas exhibiting different response features. Interestingly, both the functional organization and the neuronal specialization can be drastically affected by early deprivation, clearly showing the existence of a developmental plasticity. Some recovery seems to remain possible at later stages, and social factors may be involved.
本文综述了近期关于鸣禽领域L的文献，这些文献表明一些神经元对复杂声音，尤其是同种鸣叫声表现出明显的选择性。此外，对欧洲椋鸟的研究揭示了这个中央听觉区域存在复杂的功能组织，各子区域表现出不同的反应特征。有趣的是，早期剥夺会对功能组织和神经元特化产生极大影响，这清楚地表明了发育可塑性的存在。在后期阶段似乎仍有可能出现一些恢复，并且可能涉及社会因素。
