摘要
目的:对家兔大脑皮层诱发电位的实验进行改进。方法:使用RM6240B生物信号采集处理系统,将刺激输出电极插入家兔前爪腕部,在家兔颅骨钻孔,将通道输入电极连于钻头,电刺激并观察电位变化。结果:在家兔大脑皮层记录到诱发电位,出现主反应、次反应和后发放。结论:改进后的钻孔术,不易损伤大脑皮层,也不需暴露外周神经,操作简单,成功率高。
Objective： To improve the experiment on cerebral cortex evoked potential of rabbit. Methods： The output electrode was inserted into the rabbit＇s ex - paw, and a hole was made in its skull with a drill which is connected with input dectrede. Then RM6240B bio - signals collecting - processing system was used to evoke and observe the potential changes.Results： Evoked potentials in rabbit＇s brain had been detected including main reaction, secondary reaction and after discharge. Conclusions： The improvement of the experiment can make less damages to the cerebrum and need not expose peripheral nerves. It is easy to operate and succeed.
