澳大利亚悉尼大学生理系Burke 教授1984年4月18日来我院短期工作三周。Burke 教授在院工作期间共作了六个学术报告。第一个是感觉丧失对行为的影响。在报告中引证动物实验,表明在一定时期内动物因缺乏固定类型的视觉刺激使感觉丧失,而使与之相关的视皮层在功能结构上发生改变。例如感觉丧失,一侧视皮层与对照组相比,细胞单位放电减少,脑重减轻,电镜检查亦见视觉细胞形态改变,而且动物的视觉性行为亦发生改变。因而提示在动物发育期的一定时间内,多种类型的适宜刺激对动物或人类的神经
Professor Burke, Department of Physiology, University of Sydney, Australia, came to our hospital for short work for three weeks on April 18, 1984. Professor Burke made six academic reports during his work in the hospital. The first is the effect of loss of feeling on behavior. Citing animal experiments in the report shows that over a period of time the animals lose their sensory perception due to the lack of a fixed type of visual stimuli, leaving the associated visual cortex altered in functional structure. For example, sensory loss, one side of the visual cortex compared with the control group, the discharge of cells decreased, reduced brain weight, electron microscopy also see visual cell morphology changes, and the visual behavior of animals also changed. It is suggested that during certain period of animal development, various types of suitable stimuli may have effects on the nerves of animals or humans
