                      connectivity reflects stable characteristics of the brain,
                      or if it is modulated by the psychological and/or
                      physiological state of the participant. Based on research
                      demonstrating sex hormonal effects in task-related brain
                      activity, the present study aimed to investigate
                      corresponding differences in RS networks. RS functional
                      Magnetic Resonance Imaging (RS fMRI) was conducted in women
                      during three different menstrual cycle phases, while men
                      underwent three repeated RS fMRI testing sessions.
                      Independent component analysis was used to identify the
                      default mode network (DMN) and an auditory RS network. For
                      the DMN, RS connectivity was stable across testing sessions
                      in men, but varied across the menstrual cycle in women. For
                      the auditory network (AN), retest reliable sex difference
                      was found. Although RS activity in the DMN has been
                      interpreted as trait characteristic of functional brain
                      organization, these findings suggest that RS activity in
                      networks involving frontal areas might be less stable than
                      in sensory-based networks and can dynamically fluctuate.
                      This also implies that some of the previously reported
                      effects of sex hormones on task-related activity might to
                      some extent be mediated by cycle-related fluctuations in RS
                      activity, especially when frontal areas are involved.},
