BOLD correlates of EEG discriminating components late in the trial (Figure 6) appeared in a pattern matching the DMN (Figure 7), supporting MEG evidence for a transient nature of functional networks (de Pascuale et al., 2010). Given that we found an earlier activation in a region associated with the VAN, this supports the hypothesis for complementary roles of the DMN and VAN in directed awareness (Boly et al., 2007; Vanhaudenhuyse et al., 2011), and supports the intracranial EEG finding that transient stimulus-related activations in VAN areas occur earlier than those in DMN (Ossandon et al., 2011).
