言语习得和学习中的神经可塑性与支持或破坏语言功能的神经回路中的时间轴轨迹和经验驱动的变化机制有关。在这篇选择性的评论中，我们讨论了语音学习在语言习得中的作用，学习的“关键期”，神经可塑性的代理人，以及大脑中语言系统的独特性。特别是，我们认为有必要看看大脑行为连接使用现代脑成像技术，寻求解释的基础上的神经灵敏度，神经效率，神经特异性和神经连接在皮层水平的措施，并指出一些关键因素，可能会促进或限制第二语言学习。最后，我们强调了未来研究的理论和实践问题，并提出了优化语言学习和治疗的方法。
Neural plasticity in speech acquisition and learning is concerned with the timeline trajectory and the mechanisms of experience-driven changes in the neural circuits that support or disrupt linguistic function. In this selective review, we discuss the role of phonetic learning in language acquisition, the “critical period” of learning, the agents of neural plasticity, and the distinctiveness of linguistic systems in the brain. In particular, we argue for the necessity to look at brain–behavior connections using modern brain imaging techniques, seek explanations based on measures of neural sensitivity, neural efficiency, neural specificity and neural connectivity at the cortical level, and point out some key factors that may facilitate or limit second language learning. We conclude by highlighting the theoretical and practical issues for future studies and suggest ways to optimize language learning and treatment.
