本文对11名健康男性青年(19—24岁)秋千诱发运动病过程中自发脑电连续记录并进行了功率谱分析。结果表明:出现运动病症状后,11名被试者脑电图都有显著改变。其中8人以脑前部(额、中央)θ频段(4.0～7.75Hz)的积分值显著上升为主,并且其变化与运动病症状得分(SS)有一致性趋势,但其α频段(8.0～11.75Hz)积分值没有显著性下降。这8人中有5人出现了θ节律性爆发;另外3人则以脑后部(枕、顶)α频段的显著下降为主,其变化与SS值没有明显的一致性,θ频段没有显著性改变。脑电θ及α节律的变化在一定程度上可反映运动病症状的程度。脑电图的上述变化结合运动病时出现的困倦、四肢无力等症状可以推测,运动病发生时大脑网状结构和皮层的兴奋性受到了一定程度的抑制。
In this paper, 11 healthy male youth (19-24 years old) during swing-induced motion sickness spontaneous EEG continuous recording and power spectrum analysis. The results showed that 11 subjects had significant EEG changes after symptoms of motion sickness. Eight of them showed a significant increase in the integral value of the frontal (frontal, central) θ band (4.0-7.75Hz), and their changes were in agreement with the motion sickness symptom score (SS). However, their alpha frequency band (8.0 ~ 11.75Hz) There was no significant decrease in the integral value. Five out of these 8 individuals developed θ rhythmic outburst. The other 3 patients mainly showed a significant decrease in the posterior segment of the brain (occipital and apex), with no significant change in their SS value and no significant change in θ frequency band Sexual change. EEG and θ rhythm changes to some extent, can reflect the degree of motion sickness symptoms. EEG changes combined with movement disorders such as drowsiness, limb weakness and other symptoms can be speculated that when the motion sickness of the brain reticular structures and cortical excitability was some degree of inhibition.
