Abstract
Recent studies revealed structural and functional brain changes in heavy
smokers. However, the specific changes in topological brain connections are not
well understood. We used Gaussian Undirected Graphs with the graphical lasso
algorithm on rs-fMRI data from smokers and non-smokers to identify significant
changes in brain connections. Our results indicate high stability in the
estimated graphs and identify several brain regions significantly affected by
smoking, providing valuable insights for future clinical research.
