大脑皮层-丘脑中部非特异投射区间存在闭合线路,它的活动在人的意识方面有重要作用,人入睡时它不活动,如果它受损,如丘脑中部梗死,人就会昏迷。在国外,这个系统于上世纪八十年代才被发现,九十年代后才逐步搞清楚[1-3],而在二十世纪五十年代后期,我们中国科学院上海生理研究所已经率先报告了这个闭合线路[4-6],只是由于当时此工作的论文只能在国内期刊发表,我们和国外同行没有交流,因此这个发现不为外国科学家所知。 There is a closed circuit in the cerebral cortex-thalamic non-specific projection zone. Its activity plays an important role in human consciousness. When a person goes to sleep, it is inactive. If it is impaired, such as the infarction in the middle of the thalamic nucleus, people become unconscious. Abroad, this system was only discovered in the 1980s and gradually cleared up after the 1990s [1-3]. In the late 1950s, the Shanghai Institute of Physiology, Chinese Academy of Sciences, had already reported the first This closed circuit [4-6] was only because the papers for this work were only published in domestic journals and we did not communicate with foreign counterparts, so this finding is not known to foreign scientists.
