abstract = {Deterioration in working memory capacity (WMC) has been
associated with normal aging, but it remains unknown how age
affects the relationship between WMC and connectivity within
functional brain networks. We therefore examined the
predictability of WMC from fMRI-based resting-state
functional connectivity (RSFC) within eight
meta-analytically defined functional brain networks and the
connectome in young and old adults using relevance vector
machine in a robust cross-validation scheme. Particular
brain networks have been associated with mental functions
linked to WMC to a varying degree and are associated with
age-related differences in performance. Comparing prediction
performance between the young and old sample revealed
age-specific effects: In young adults, we found a general
unpredictability of WMC from RSFC in networks subserving WM,
cognitive action control, vigilant attention, theory-of-mind
cognition, and semantic memory, whereas in older adults each
network significantly predicted WMC. Moreover, both
WM-related and WM-unrelated networks were differently
predictive in older adults with low versus high WMC. These
results indicate that the within-network functional coupling
during task-free states is specifically related to
individual task performance in advanced age, suggesting
neural-level reorganization. In particular, our findings
support the notion of a decreased segregation of functional
brain networks, deterioration of network integrity within
different networks and/or compensation by reorganization as
factors driving associations between individual WMC and
within-network RSFC in older adults. Thus, using
multivariate pattern regression provided novel insights into
age-related brain reorganization by linking cognitive
capacity to brain network integrity.},
