| Abstract: | Background The default network is a set of brain regions that exhibit a reduction in BOLD response during attention-demanding cognitive
tasks, and distinctive patterns of functional connectivity that typically include anti-correlations with a fronto-parietal
network involved in attention, working memory, and executive control. The function of the default network regions has been
attributed to introspection, self-awareness, and theory of mind judgments, and some of its regions are involved in episodic
memory processes. |
