When not engaged in the moment, we often spontaneously represent people, places and events that are present environment. Although this capacity has been linked to default mode network (DMN), it remains unclear how interactions between nodes of give rise particular mental experiences during spontaneous thought. One hypothesis is core DMN integrates information from medial lateral temporal lobe memory systems, which different aspects knowledge. Individual differences connectivity regions would then predict content form people’s thoughts. This study tested by examining relationship seed-based functional contents thought recorded a laboratory several days later. Variations both was associated with patterns these effects converged on an overlapping region posterior cingulate cortex. We propose acts as representational hub represented process important determining
