选择性地回顾了最近有关丘脑失语症和神经影像学期间丘脑活动的文献，然后考虑了有关丘脑结构和功能的最新解剖学和生理学发现。结论是，四种相关的皮质丘脑和/或丘脑皮质机制影响语言处理：（1）部分通过网状核（NR）选择性参与处于高度反应状态的任务相关皮质区域，（2）通过皮质丘脑-皮质机制将信息从一个皮质区域传递到另一个皮质区域，（3）通过皮质丘脑-皮质反馈机制加强对任务相关信息的关注，以及（4）选择一种语言在概念的表达中，一个单位高于另一个单位，与基底神经节环协同完成。对这些机制的关系和相互作用进行了讨论，并将其与丘脑失语症和神经影像数据整合成丘脑语言功能理论。
Recent literature on thalamic aphasia and thalamic activity during neuroimaging is selectively reviewed followed by a consideration of recent anatomic and physiological findings regarding thalamic structure and functions. It is concluded that four related corticothalamic and/or thalamocortical mechanisms impact language processing: (1) selective engagement of task-relevant cortical areas in a heightened state of responsiveness in part through the nucleus reticularis (NR), (2) passing information from one cortical area to another through corticothalamo-cortical mechanisms, (3) sharpening the focus on task-relevant information through corticothalamo-cortical feedback mechanisms, and (4) selection of one language unit over another in the expression of a concept, accomplished in concert with basal ganglia loops. The relationship and interaction of these mechanisms is discussed and integrated with thalamic aphasia and neuroimaging data into a theory of thalamic functions in language.
