摘　　要：鸣禽的鸣唱控制系统已成为研究神经系统与学习、行为和发育相关的一个重要模型.鸣禽的鸣啭表现出一种复杂的学习过程.鸣禽学习鸣啭的过程可以分为两个阶段.在感觉学习期,幼鸟必须听到成鸟的鸣啭,并形成鸣啭模板记忆;在感觉运动学习期,鸣禽通过听觉反馈与模板匹配逐步建立稳定的鸣啭.该文对近年来鸣禽鸣啭学习过程中的新生神经元及长时程增强研究进展进行综述.The song control system of birds has become an important model for studying neural system related to learning, behavior, and development. In songbirds, vocal learning is accomplished in two phases. During the initial, sensory phase, birds listen to and memorize a tutor song, and form an internal representation of a song template. In the later, sensorimotor phase, birds gradually match their vocalizations to the memorized song, using auditory feedback from their own vocalizations. In this paper, it is reviewed the processes about new neurons and long -term potentiation which contribute to song learning.
