吸烟对注意网络的影响研究

目的探讨烟碱对人的注意网络的影响。方法运用注意网络测试,对有吸烟史者和无吸烟史者烟碱摄入前后进行注意网络功能的检查。结果吸烟史者注意网络检查示烟碱摄入后平均反应时间显著缩短(P<0·05)。无吸烟史者注意网络检查示烟碱摄入后执行控制反应时缩短降低(P<0·05)。吸烟史组较无吸烟史组在烟碱摄入前平均反应时间显著延长(P<0·05)。结论烟碱(尼古丁)摄入时间的长短对人的执行控制网络和平均反应时的影响是不同的。

The retlationship of attention networks and nicotine

Objective To elucidate correlation between attention networks and nicotine.Methods Used the attention network test.As part of the parent study,all participants were asked questions about smoking behavior,they were divided in two groups.The first group is non-smoking and the second is smoking.50 males were all healthy at least 18 years free of medical or psychiatric health complications.Results Non-smoking showed significantly positively correlated with the executive control network effects and RT after administration of nicotine(P<0.05).Smoking showed deficits in RT(P<0.05).Non-smoking and smoking showed significantly positively in RT before administration of nicotine(P<0.05).Conclusion As we all know,regularly smoking is harm to cognition.The smoking suffers executive control networks deficits.The attention damages of the nicotine are correlated with the length of time.The attention networks of non-smoking are improved after administration of nicotine.Overall our findings identify that the length of time of administration of nicotine impact different in the attention networks.
