中国树鼩和大鼠大脑皮质功能探索
Function Investigation of the Cerebral Cortex of Chinese Tree Shrews and Wistar Rats
摘要
Abstract
To examine whether destruction of cerebral cortex affects body movement and feeling,electric coagulation destruction on the cerebral cortex in Chinese tree shrews and Wistar rats was applied to study and the animal's movement by assessing the score of Longa,Berderson and swimming test.The results demonstrated that bilateral destruction of the brain cortex did not affect the animal's body motor and sensory paralysis and obstacles,diet and activity.The Longa,Berderson score for the animals from different groups are 0.The swimming endurance experiments of rats showed that the swimming time before submersion in water in control group was 36.2±0.6 min and the cerebral cortex-destructed group was 34.4±0.2 min; sink times were 13.1±0.3 and 11.7±0.4 times; the swim total time were 78.1±2.6 min and 76.3±1.4 min respectively.Therefore,there is no significant difference between control and cortex-destructed animals in terms of the three indicators that we used to check the body movement (P＞0.05).Experimental results showed that the cerebral cortex is not the direct control of the body movement and sensory center for stimuli.关键词
