本文系作者用正电子发射断层扫描仪测量单字认知过程中脑部血流变化,其结果对于许多临床常用的关于语言认知的神经学模型提出异议。受试者为17位右利正常人(男6,女11)。在静脉注射0~(15)标记的水(半衰期123秒)后,使用英文名词给予视、听刺激。每人检测时间40秒,同时进行脑血流量的断层们描记录。检测分为四个状态(背景记录、被动单词展示、主动单词复述、单词意义描述)单纯大声复述“蛋糕”时的记录即可得到第Ⅲ个层次上的脑血流分布结果,其余类推。所有结果进行统计学等技术处理。
In this paper, we used positron emission tomography to measure changes in brain blood flow during single-word cognitive process, and the results challenged many of the most commonly used neurological models of language cognition. The subjects were 17 right-normal subjects (male 6, female 11). After intravenous injection of 0 ~ (15) labeled water (half-life of 123 seconds), the use of English terms given to visual, to stimulate. Detection time of 40 seconds per person, at the same time, the blood flow of the brain were recorded. The test is divided into four states (background record, passive word display, active word repetition, word meaning description) to simply recite “cake” records to get the third level of cerebral blood flow distribution results, and so on. All results for statistical and other technical treatment.
