The Default Mode Network and Frontoparietal Control Network are functionally linked as core components of human cognition, with research highlighting their joint modulation by psychedelics [1], their shared role in evolutionary cortical expansion [2], and their collaborative function as a 'connective core' supporting consciousness [3]. Furthermore, studies emphasize the importance of analyzing these networks together to avoid biases in understanding their respective roles in brain activity [4].

claimPsychedelics functionally modulate the activity and connectivity of the frontoparietal network and the Default Mode Network (DMN), which can enhance cognitive functioning and sociality, according to research by Carhart-Harris and Friston (2019), Vollenweider and Preller (2020), Cini et al. (2019), and Preller and Vollenweider (2019).
claimRapid evolutionary cortical expansion and reorganization in the human brain is most pronounced in higher-order cognitive networks, specifically the frontoparietal network and the Default Mode Network (DMN), and runs parallel with high expression of human-accelerated genes (HAR genes) involved in synapse and dendrite formation, according to Wei et al. (2019).

referenceShanahan hypothesized that the Frontoparietal Network (FPN) and Default Mode Network (DMN) tandem functions as a 'connective core' along the brain's medial axis to support consciousness.
claimThe reliance on 'resting-state' data without external stimuli may have resulted in an overestimation of the Default Mode Network's (DMN) role in consciousness and an under-estimation of the Frontoparietal Network (FPN), including the lateral prefrontal cortex, due to their different recruitment during no-task conditions.
