Left thalamic lesions can produce motor speech disturbances: disorders of articulation and of phonation. Left thalamic lesions can also produce aphasic disorders: word-emission difficulties; difficulties with comprehension, reading, writing, and arithmetic; and sometimes suppression of conversational propositional speech with preservation of nonpropositional repetitional or automatic speech. The relative preservation of nonpropositional speech justifies the assignment of such cases of thalamic aphasia to the category of transcortical aphasia (TA). Also included in TA are aphasias from dominant hemisphere supplementary motor region (SMR) lesions. In this context the suggestion by Penfield and Roberts that the thalamus and the SMR interact via the pedunculus thalami superior is noted.
发音和发声障碍。左侧丘脑病变还可导致失语症：言语表达困难；理解、阅读、书写和算术困难；有时会抑制对话性命题言语，而非命题性重复或自动言语得以保留。非命题性言语的相对保留证明了将此类丘脑性失语症归为经皮质失语症（TA）范畴的合理性。TA还包括优势半球辅助运动区（SMR）病变所致的失语症。在此背景下，请注意彭菲尔德和罗伯茨提出的丘脑与SMR通过丘脑上脚相互作用的观点。
