      abstract     = {BackgroundCognitive insight is defined as the ability to
                      reflect upon oneself (i.e. self-reflectiveness), and to not
                      be overly confident of one's own (incorrect) beliefs (i.e.
                      self-certainty). These abilities are impaired in several
                      disorders, while they are essential for the evaluation and
                      regulation of one's behavior. We hypothesized that cognitive
                      insight is a dynamic process, and therefore examined how it
                      relates to temporal dynamics of resting state functional
                      connectivity (FC) and underlying structural network
                      characteristics in 58 healthy individuals.MethodsCognitive
                      insight was measured with the Beck Cognitive Insight Scale.
                      FC characteristics were calculated after obtaining four FC
                      states with leading eigenvector dynamics analysis. Gray
                      matter (GM) and DTI connectomes were based on GM similarity
                      and probabilistic tractography. Structural graph
                      characteristics, such as path length, clustering
                      coefficient, and small-world coefficient, were calculated
                      with the Brain Connectivity Toolbox. FC and structural graph
                      characteristics were correlated with cognitive
                      insight.ResultsIndividuals with lower cognitive insight
                      switched more and spent less time in a globally synchronized
                      state. Additionally, individuals with lower
                      self-reflectiveness spent more time in, had a higher
                      probability of, and had a higher chance of switching to a
                      state entailing default mode network (DMN) areas. With lower
                      self-reflectiveness, DTI-connectomes were segregated less
                      (i.e. lower global clustering coefficient) with lower
                      embeddedness of the left angular gyrus specifically (i.e.
                      lower local clustering coefficient).ConclusionsOur results
                      suggest less stable functional and structural networks in
                      individuals with poorer cognitive insight, specifically
                      self-reflectiveness. An overly present DMN appears to play a
                      key role in poorer self-reflectiveness.},
