The model of brain concussion of rat can be established successfully using iron pendulum hitting device; 2. The spatial learning and memory deficits of the rats are detected by MWM in early period post-BC(from 1 to 3 days after BC); 3. Pycnosis degeneration or necrosis neurons of the cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation are identified in BC rats; 4. There are significantly changes in the number and activity of cholinergic neurons in the basal forebrain and brainstem reticular formation after BC; 5. The change of cerebral neurons and cholinergic neurons correlate with cognitive deficits in BC rats .

1、单摆式闭合性机械打击装置能成功建立脑震荡大鼠模型；2、脑震荡大鼠在MWM实验中出现早期空间认知行为障碍；3、脑震荡大鼠大脑皮质、背侧海马、齿状回和脑干网状结构出现程度不等的部分神经元固缩变性和不完全性坏死；4、脑震荡大鼠基底前脑、脑干网状结构ChAT活性表达有明显变化；5、脑震荡大鼠认知障碍与相关脑区神经元、胆碱能神经元的变化有关联。

Methods: A brain concussion was produced in rats using a simple pendulum device model. One control (n=12) and six experimental groups were used(n=12 in each group). The cerebral concussion groups were assigned to sacrifice times ranging from 1 day to 24days after injury.A Morris Water Maze memory paradigm was used to assess learning and memory function. Pycnosis degeneration or necrosis neurons in the locus cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation were observed and counted after brain concussion. Cholinergic neurons in the basal forebrain and brainstem reticular formation were identified and quantitated using choline acetyltransferase.
