1.Progress on Song Learning of Songbirds
2.The canary was trilling away in its cage.
3.Birds have begin to chirp and twitter among the tree.
4.In this paper, we reviewed the processes which contribute to song learning .
5.If a warmly warbling warbler warbles to another armly warbling warbler, which warmly warbling warbler warbles warmest?
如果一只热情的鸣鸟对另一只热情的鸣鸟
鸣啭，哪只热情鸣鸟
鸣啭得最热情？
6.It reviewd the effect of sex steroid hormone in vocal learning of young bird and song plasticity of adult bird in the level of neuron,circuits and behavior.
从细胞回路水平、行为水平对性激素在幼年鸣禽发声学习和成年鸣禽
鸣啭可塑性中的作用进行了全面论述。
7.After finishing the recording, we measured the volumes of forebrain song control nuclei: HVC, RA and Area X and a control nucleus, rotundus nucleus (Rt) (a diencephalic nucleus involving in visual relay).
然后 ,测定了前脑三个
鸣啭学习控制核团和一个与发声无关的视觉参考核团体积 ,分析了鸣唱语句复杂性和这些核团大小间的相关关系。
8.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.
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。
