In this study, we explored gender- and age-related effects on resting state (RS) functional connectivity within and among networks with potential functional relevance. RS data were acquired from 285 healthy controls (148 men and 137 women, range=8-79 years). Abnormalities of connectivity within and among networks, as detected by independent component analysis and functional network connectivity, were found in almost all RS networks; however, age and gender effects were variable across networks. Our results might contribute to the understanding of gender-related differences in the pathobiology of aging.
