| 摘 要： | 目的：观察次声对兔脑电活动的影响。方法：新西兰白兔分别暴露于频率为8Hz和16Hz、声压为90dB和130dB的次声场内20min，采用EEG Holter记录穿颅皮层脑电波的活动变化。结果：在16Hz次声作用下，实验兔脑电慢波出现量明显增多。结论：声强为90dB和130dB的16Hz次声波对实验兔脑电活动有一定抑制作用。

The effect of exposure to infrasound on EEG of rabbits |
| |
| Abstract: | Objective To observe the effect of exposure to infrasound on EEG of rabbits. Methods Forty New Zealand rabbits were used for this study. Thirty two rabbits served as experimental subjects for EEG recordings by using EEG Holter during the exposure to infrasound of 8 Hz and 16 Hz with the intensity of 90 dB and 130 dB for 20 minutes, respectively. Eight rabbits served as control. Results No spine wave and sharp wave were recorded in the experimental and control animals. The EEG slow waves of the rabbits exposed to infrasound of 16 Hz with the intensity of 90 dB and 130 dB increased significantly compared with the control and other experimental animals ( P < 0.05 ). Conclusion The electrical activity of rabbit's brain can be inhibited by exposing to infrasound of 16 Hz with the intensity of 90 and 130 dB. |
