摘　　要：神经递质在鸣禽脑中不仅是神经元间信号传递的中介物质，还有资料表明它们通过在习鸣敏感期影响发声控制核团间的突触联系的形成和突触可塑性，从而对鸣啭类型的确定和巩固起重要作用。本文着重介绍了鸣禽发声控制核团内神经递质的分布及变化情况，并就神经递质在发声学习中的作用进行了探讨。In the songbirds brain neurotransmitters play an important role not only in signal conduction between neurons in the establishment and consolidation of song types by affecting the synapse connection and synapse plasticity between song control nuclei during the sensitive period of vocal learning in songbirds. This article focuses on the distribution and changes of neurotransmitters in song control nuclei of songbirds. Effect of neurotransmitters on vocal learning is discussed.
