Age-related differences in generalized patterns of localized connections. Following two patterns are highlighted as examples of age-related variation in localized network across four frequency-specific bands of connectivity: pattern M for α-band connectivity and pattern S for β-band connectivity. Significant differences for each age group in terms of the energy (middle panel) and entropy (right panel) of the four patterns as well as statistical analysis of the two groups without considering age factors (inset) were observed. * indicates network pairs with significantly different connections between groups (*, **, and *** indicate p < 0.05, p < 0.01, and p < 0.001, respectively).
