The eyes closed vs. eyes open conditions were measured at different times with a pause between recordings and thus are within subject replications. Both conditions exhibited significant fits to the exponential Equation (1) and there were no significant differences between eyes open and eyes closed phase shift duration (see Table 4). The eyes closed condition did exhibit a small but significantly longer phase lock duration which may reflect the relatively small differences in neural excitability between these two states. The lack of a large difference between resting eyes closed and eyes open states is consistent with fMRI studies of the DMN that is evident in the resting state (Raichle, 2010). This is because the resting state is characterized by quiet repose with either eyes closed or eyes open and with or without visual fixation. During the resting state subjects typically experience an ongoing state of conscious awareness filled with “stimulus-independent thoughts” (SITs; Antrobus, 1968) or more commonly, day dreaming or mind wandering (Mason et al., 2007). Internal thoughts, self-awareness and rumination commonly dominate the resting state as opposed to active
