鸣禽鸣叫学习的神经生物学机制

鸣禽鸣叫具有复杂的神经生理和生化基础，表现为一种复杂的学习过程。鸣啭控制系统是研究神经系统与学习、行为和发育关系的重要模型。而鸣禽鸣叫学习行为与鸣啭控制系统内长时程增强效应、神经元超微结构的改变和神经核团内的电活动、激素水平高低及其周期性变化、神经元再生或改变、即早基因的表达等方面密切相关。对鸣禽鸣叫的神经生物学机制进行了综述。

Neurobiological mechanisms on the vocal learning of songbirds

Songbirds have a complex physiological and biochemical mechanisms for the behaviour of vocla learning, which manifests that a complex process. The vocal control system of songbirds has become an important model for studying the neural system related to learning, behavior, and development. The learning behaviour of songbirds is closely related to the changes of vocal control systems such as the long-term potentiation effect, ultrastructural changes of neurons, the physiological activities of neurons, the level and cyclical changes of hormones, the regeneration and changes of neurons, the expression of immediate early genes etc. The neurobiological mechanisms on the vocal learning of songbirds are reviewed in this paper.
