Biological Psychiatry: whether or not smoking and smoking status affect intrinsic functional connection

Smoking behavior within the first 24 hours of a smoking cessation attempt is an important predictor of long-term smoking cessation, but little is known about the neurobiology of early smoking cessation.

The study used a mixed design within and between subjects to evaluate the impact of smoking status (yes/not a smoker) and status (deprivation vs.

The analysis based on NOI shows that compared with non-smokers, the functional connectivity of the frontal top and the significant network of smokers is reduced, just as smoking status affects the connectivity of the default mode.

Comparison of the internal connectivity of the whole brain between non-smokers and smokers under deprivation and satiety

Comparison of non-smokers and smokers in deprivation and satisfaction based on the functional connection of seed points

These data show the importance of considering smoking status and the practicality of using theoretical and data-driven analysis methods.
