对海洛因依赖者三种长潜时脑诱发电位主成分分析

PERTINENCY OF THREE LONG-LATENCY BRAIN EVOKED POTENTIALS IN HEROIN DEPENDENT PATIENTS

目的:提高海洛因依赖者三种长潜时脑诱发电位指标反映的信息量。方法:采用事件相关电位P300、听觉诱发电位、视觉诱发电位技术对32例海洛因依赖者检测,运用SPSS统计软件进行主成分分析。结果:用主成分分析的方法,从海洛因依赖者三种长潜时脑诱发电位的24个电生理指标中提取出8个主成分,其反映的信息量为原有信息量的80.318%。结论:这8个主成分能反映海洛因依赖者绝大部分脑电信息,并结合神经心理测验可进一步揭开依赖者的心理活动。

Objective ： To increase the information of three long - latency brain evoked potentials in heroin addicts. Methods： A test was conducted in 32 eases with heroin dependence using the technologies of event - related potential P300, auditory evoked potential and visual evoked potential. The data were analyzed using the main ingredients in SPSS statistical software. Results：There were eight main ingredients from 24 electric physiological indicators,which reflected 80. 318% of the amount of original information. Conclusion： These eight main elements may delegate the majority of brain - electric information of heroin addicts, and a combination of nerves psychological test can further rely on the psychological activities.
