doi  abstract   bibtex   
The discovery of the default mode network (DMN) has revolutionized our understanding of the workings of the human brain. Here, I review developments that led to the discovery of the DMN, offer a personal reflection, and consider how our ideas of DMN function have evolved over the past two decades. I summarize literature examining the role of the DMN in self-reference, social cognition, episodic and autobiographical memory, language and semantic memory, and mind wandering. I identify unifying themes and propose new perspectives on the DMN's role in human cognition. I argue that the DMN integrates and broadcasts memory, language, and semantic representations to create a coherent "internal narrative" reflecting our individual experiences. This narrative is central to the construction of a sense of self, shapes how we perceive ourselves and interact with others, may have ontogenetic origins in self-directed speech during childhood, and forms a vital component of human consciousness.

* Employing a novel experimental paradigm that modeled the listener’s brain activity from a speaker’s activity, it was found that speaker and listener brain activities were temporally correlated in the mPFC and PCC nodes of the DMN. ( Stephens, G.J., Silbert, L.J., and Hasson, U. (2010). Speaker–listener neural coupling underlies successful communication. Proc. Natl. Acad. Sci. USA 107, 14425–14430.)
* I propose that the DMN integrates these cognitive functions to create a coherent internal narrative of our experiences.},
