大脑皮层诱发电位是指感觉传入系统受刺激时,在皮层上某一局限区域引出的电位变化。以这种电位变化作为指标可以反映中枢神经系统的感觉机能,并能对感觉投射的精确定位作出正确评价。过去我室学生记录皮层诱发电位的动物大多用兔,由于所用动物较大,操作繁杂,且脑皮层极易出血,实验成功率较低,影响了学生利用此法对中枢神经系统感觉传入机
Cerebral cortex evoked potentials refer to changes in electrical potential induced in a localized area of the cortex when sensory afferent systems are stimulated. Using this change in potential as an index can reflect the sensory function of the central nervous system and make a correct assessment of the precise positioning of the sensory projection. In the past, most of our students used cortical evoked potential animals to use rabbits. Due to the large animals used and complicated operation, the cerebral cortex was extremely easy to bleed. The success rate of experiment was low, which affected the students to use this method to sensory afferent central nervous system
