Although the mean path length and the small world index did not show a significant session × group interaction, node strength showed a trend toward a session × group interaction ( F (4,36) = 2.2, p = 0.08; a Tukey’s post hoc test indicated reduced node strength in cocaine and sucrose rats relative to chamber exposure controls, p < 0.05; Fig. 5 A ).
