In this work the visual, auditory, somatosensory evoked cortical potentials as well as raw EEGs were observed in 31 rabbits either anesthetized with urethane or conscious. The effects of acupuncture on them were as follows: 1) The main components of the evoked potentials were significantly depressed; 2) The raw EEGs were desynchronized while the animals appeared to be slightly activated; 3) Both the integral values of raw EEGs and the powers of lower frequency waves (1-3.99 Hz) were decreased and positively correlated well with the amplitudes of the main components of the evoked potentials. Therefore, It could not be ruled out that the effects of acupuncture on the evoked potentials are secondary to the changes of EEGs, and it is suggested that the inhibition of evoked potentials during acupuncture does not necessarily mean that the cerebral cortex is in an inhibitory state.
在这项研究中，对31只使用氨基甲酸乙酯麻醉或清醒的家兔观察了视觉、听觉、躯体感觉诱发皮层电位以及原始脑电图。针刺对它们的影响如下：1）诱发电位的主要成分明显降低；2）原始脑电图去同步化，而动物似乎略有激活；3）原始脑电图的积分值和低频波（1-3.99赫兹）的功率均降低，且与诱发电位主要成分的振幅呈良好正相关。因此，不能排除针刺对诱发电位的影响继发于脑电图的变化，并且提示针刺过程中诱发电位的抑制不一定意味着大脑皮层处于抑制状态。
