摘要
鸣禽鸣唱与人类说话一样,都是在教习和听觉反馈下形成的感知运动学习过程。鸣禽鸣唱的发育和成熟巩固依赖于发声通路和前端脑通路组成的鸣唱系统的完整。前端脑通路中的X区在鸣唱学习记忆中扮演着重要角色。本文就X区的形态组织结构、在鸣唱发育与成熟巩固中的作用、突触可塑性的研究进展进行了综述,并且将X区与哺乳动物基底神经节的学习记忆功能做了比较。
Like human speech, singing of songbirds is sensorimotor learning by tutor and auditory feedback. The development and crystallization of singing is depended on the integrity of the song system composed of vocal pathway and anterior forebrain pathway. X area in forebrain pathway plays an important role during learning and memory of singing. In this paper, we reviewed studies on the organization and the function in singing development and crystallization, the synaptic plasticity of X area. We also compared learning and memory function of X area to that of mammalian basal ganglia.
