Auditory Filial Imprinting in the Domestic Chick

雏鸡听觉印记学习是研究新生个体在早期发育阶段学习与记忆形成的神经机制的良好实验模型。听觉刺激对印记学习有很好的强化作用,作用效果依赖于频率、强度和持续时间等声音特征。从声音的选择、听觉刺激所引起的分子水平和组织水平改变等方面综述雏鸡听觉印记学习的研究进展。

Auditory filial imprinting of domestic chicks is an attractive experimental model for studying the neuronal mechanisms of learning and memory formation during early postnatal development. Auditory stimulation during imprinting facilitates recognition and memory of the imprinting model, and its ,efficacy depends on particular characteristics of the auditory stimulus such as frequency, intensity and duration. The progresses on auditory filial imprinting in the domestic chick were summarized in this paper from sound selection, changes in molecular level and tissue level which caused by auditory stimulation.
