新纹状体巨细胞核外侧部（LMAN）与鸣禽鸣唱学习可塑性

鸣禽鸣唱控制系统的前端脑通路（anterior forebrain pathway, AFP）在鸣唱学习中发挥着重要作用。新纹状体巨细胞核外侧部（lateral magnocellular nucleus of the anterior neostriatum, LMAN）是AFP的最后一级输出核团，AFP中的信号通过LMAN传导到弓状皮质栎核（robust nucleus of the arcopallium, RA），与高级发声中枢（high vocal centre，HVC）共同调节RA的活动，从而影响鸣禽的发声行为。LMAN可能通过其与RA的单突触连接来影响鸣唱可塑性。文章对近年来LMAN在鸣唱学习可塑性方面的研究进行综述。

LMAN AND THE PLASTICITY OF VOCAL LEARNING IN SONGBIRDS

The anterior forebrain pathway (AFP) of the song system in songbirds plays an important role in vocal learning in songbirds. The lateral magnocellular nucleus of the anterior neostriatum (LMAN) is the last output nucleus of AFP. AFP transmits the signals to the robust nucleus of the arcopallium (RA) by LMAN. LMAN and the high vocal centre (HVC) regulate the activity of RA and they make an impact on the vocal behavior. LMAN is likely to affect vocal plasticity via its monosynaptic connections with RA, a vocal motor area critical to song production throughout life. Here, the progress of LMAN and the plasticity of vocal learning in songbirds are reviewed in recent years.
