task induced changes, including a reduced clustering coefficient and network efficiency, in the elderly subjects, aligning our results with previous studies on performing a visual WM task [43]. Cognitive decline has been associated with structural and functional reorganization, with aging affecting cognitive performance in elderly populations [65,66]. WM has also been shown to be advantageous in increasing connectivity efficiency, and it is also useful for network reconfiguration to applying WM training in elderly subjects [43].
