| 摘 要： | 揭示学习与记忆的神经机制已成为认知科学领域的一个重要研究方向.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.LTP(long term potentiation)是一种研究学习记忆突触基础的主要模型,其代表突触功能的可塑性.本文对近年来鸣禽神经系统可塑性及习鸣研究进展进行综述.

| Abstract: | Neural mechanism in learning and memory is an important research field for cognitive science.Song of songbird display complex learning.In songbird,vocal learning is accomplished in two phases.During an initial,sensory phase,birds listen to and memorize a tutor song,and form an internal representation of a song template.In a later,sensorimotor phase,birds gradually match their vocalizations to the memorized song,using auditory feedback from their own vocalizations.LTP represents a long-lasting enhancement of synaptic function,is a kind of primary model for synaptic plasticity that underlies learning and memory.New progress in birdsong and the plasticity in development of song control system in recent years are focused. |
