Control network coupling modulated by task in young and old adults. In the young adults, the control network is reliably correlated with the default network during autobiographical planning, but not during visuospatial planning, across the trial interval. Also in the young, the attention network is reliably correlated with the control network during visuospatial planning but not during autobiographical planning. In the old adults, the control network is reliably correlated with the default network during autobiographical and visuospatial planning. Also in the old adults, the attention network is reliably correlated with the control network during visuospatial planning, and to a lesser extent, autobiographical planning. The magnitude of correlation between the control and default network during visuospatial planning is significantly different between young and old adults. Standard error of the mean is between subjects effect. *P < 0.01; **P < 0.001; † significant difference from baseline.
