This paper faced the most challenging peer review process I’ve experienced in my career - a years-long journey with numerous submissions - but I’m glad to say that the end product is substantially improved! 11/

We speculate that DN-B and A may both support the core function of constructing internal relational models, but in separate content domains: ToM-like models of familiar people, and cognitive maps of familiar places 10/

Person-preferring areas corresponded closely to DN-B. Place-preferring areas were predominantly observed in DN-A, with responses additionally observed in VIS-P and dATN-A/B (if you’ve already seen our preprint, skip to Fig 4 for these new results) 9/

Areas preferring people or places were functionally connected across frontal, parietal, and temporal cortex, with each system reaching the apex of a unimodal-to-transmodal gradient 8/

These responses were reliably observed across each task context, suggesting for a dissociation based on content domain rather than cognitive process 7/

We found that separate areas of association cortex responded to task conditions involving people or places, respectively 6/

We tested this view with a precision fMRI approach, scanning individuals while performing visual, semantic, and episodic tasks involving familiar people or places, or generic objects 5/

One possibility is that each network supports a distinct cognitive process, such as social cognition and episodic memory. Here we argue for an alternative: the two systems support a common process acting on distinct content domains (people and places) 4/

Recent work has advanced this debate by demonstrating the DMN in fact comprises two separate, interdigitated networks, termed DN-A and B. How should we understand the functional dissociation between these two systems? 3/

We address the longstanding question of how to understanding the function of the "default mode network," which has been argued to support a staggering range of processes - social cognition, long-term memory, internally generated thought, spatial navigation, etc 2/
