长期以来,语言功能与脑结构之间关系的研究主要依赖两个方法:(1),在局部脑损伤的失语症病人上作神经病理研究及在做过某些脑部位切除手术的病人上作语言行为研究,这类方法在于确立脑的某一部位的损伤与语言紊乱的联系;(2),在治疗癫痫病人做脑外科手术时,观察刺激有关皮层对语言行为的效应。此外还有两个较次要的方法,a.利用神经放射学技术(如脑血管放射线造影)对与语言紊乱有关的脑损伤部位定位;b.自一侧颈总动脉注射巴比妥盐(barbitunate)(Wada 测验),使一侧脑半球暂时抑制,进行语言行为研究。毫无疑
For a long time, the study of the relationship between language function and brain structure has mainly relied on two methods: (1) neuropathological studies on patients with aphasia of local brain injury, and on patients who underwent some brain excision As a language behavior research, this kind of method is to establish the relationship between the damage of a certain part of the brain and language disorder; (2) To observe the effect of stimulating the cortical on linguistic behavior in the treatment of epileptic patients during brain surgery. In addition, there are two more secondary approaches, a. The use of neuroradiology techniques such as cerebral angiography to locate the location of a brain injury associated with a language disorder; b. The injection of barbiturate from the common carotid artery barbitunate (Wada test), to temporarily inhibit the side of the cerebral hemisphere, language behavior studies. No doubt
