5. Conclusion
By applying the background connectivity approach, this study considered
the alterations of brain activities and connectivity and their roles in
WM ageing. The findings revealed independent age-related changes between
two functional features and identified that they exhibited
counterbalanced impacts on age-related changes in WM performance, which
provided a richer repertoire of brain dynamics in ageing, a possible
explanation from connectivity on the brain compensation in ageing, with
implications for a comprehensive understanding of higher cognitive
functions and their alterations during ageing or disease-related
processes.
