【摘要】：目的:利用功能磁共振成像技术观察吸烟成瘾者在戒烟前后视觉信息处理的差异。方法:17名吸烟成瘾者同意戒烟并完成了试验。利用独立分量分析方法分解出初级视觉网络和次级视觉网络。在两个网络内,戒烟前后存在显著差异的区域作为感兴趣区域,并对这些区域进行基于感兴趣区的功能连接分析。结果:戒烟14 d后在次级视觉网络内、两个网络之间的功能连接均有所增强,在初级视觉网络内的功能连接相对稳定。结论:吸烟成瘾者在戒烟14 d后视觉信息处理能力显著增强。
[Abstract]:Objective: to observe the difference of visual information processing before and after smoking cessation by using functional magnetic resonance imaging (fMRI). Seventeen smokers agreed to quit smoking and completed the experiment. The primary visual network and the secondary visual network were decomposed into two networks using independent component analysis (ICA). The regions with significant differences before and after smoking cessation were regarded as regions of interest, and the functional connections of these regions were analyzed based on the regions of interest. Results: after 14 days of smoking cessation, they were in the secondary visual network. The functional connections between the two networks were enhanced, and the functional connections in primary visual networks were relatively stable. Conclusion: the ability of visual information processing in smokers after 14 days of smoking cessation is significantly enhanced.
