The Default Mode Network is a neural network that is active when people deal with their inner self. This includes being in an awake idle state, introspection, engaging with autobiographical memory, imagining the future, and thinking about the perspectives of others. Core areas of the network are the ventromedial prefrontal cortex, the posterior cingulate cortex, the inferior parietal lobule, the lateral temporal cortex, the dorsomedial prefrontal cortex, and the hippocampus.
