社会性物种表现出的许多复杂行为首先是通过模仿其他更有经验的个体的行为来学习的。言语和语言是以这种方式学习的最受欢迎的行为。鸣禽的声音模仿可能是研究得最好的社会传播行为,过去几年的研究已经开始破解鸣禽如何从声音模型中学习的电路机制。对斑胸草雀的研究揭示了前运动皮层回路在形成用于指导歌曲模仿的行为目标记忆中的意外和重要作用,挑战了用于模仿的歌曲记忆存储在听觉回路中的观点。在这里,我们提供了一个总结这一最新进展,重点是什么,在哪里,以及如何家教歌曲记忆,并提出了一个电路假说的基础上,这些最新的研究结果的歌曲学习。
Many complex behaviors exhibited by social species are first learned by imitating the behavior of other more experienced individuals. Speech and language are the most widely appreciated behaviors learned in this way. Vocal imitation in songbirds is perhaps the best studied socially transmitted behavior, and research over the past few years has begun to crack the circuit mechanisms for how songbirds learn from vocal models. Studies in zebra finches are revealing an unexpected and essential role for premotor cortical circuits in forming the behavioral-goal memories used to guide song imitation, challenging the view that song memories used for imitation are stored in auditory circuits. Here, we provide a summary of this recent progress focusing on the What, Where, and How of tutor song memory, and propose a circuit hypothesis for song learning based on these recent findings.
