The default mode network is widely recognized as a critical component of consciousness, with its activity and connectivity patterns serving as indicators of conscious states [1], [2]. Research highlights that alterations in consciousness, whether through meditation, psychedelics, or brain injury, are fundamentally linked to disruptions or changes in the default mode network's function [3], [4], [5], [6]. Furthermore, the network is hypothesized to act as a 'connective core' supporting conscious experience [7], [8].

referenceThe Default Mode Network is functionally and anatomically connected with the thalamus and precuneus, a connectivity that is crucial to consciousness, according to Cunningham et al. (2017).
claimThe common mechanisms underlying diverse alterations of consciousness involve the disruption of normal functions in the prefrontal cortex and the default mode network (DMN).
claimPsychedelics and other processes that alter consciousness share common mechanisms involving the disabling of the prefrontal cortex and default mode networks.
claimReduced activity and connectivity within the Default Mode Network (DMN) are observed in both psychedelic use and various non-pharmacological methods for altering consciousness.
claimPanda et al. (2016) found that temporal dynamics of the default mode network characterize meditation-induced alterations in consciousness.

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.
referenceThe paper 'Default network connectivity reflects the level of consciousness in non-communicative brain-damaged patients' by Vanhaudenhuyse et al. (2010) establishes that connectivity within the default mode network correlates with the level of consciousness in patients with brain damage who cannot communicate.
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.

claimThe default mode network is characterized by almost nonstop activity that lacks a visible relation to specific operational needs or external messages, which is similar to the incessant stream of thoughts associated with consciousness.
claimThe default mode network is involved in consciousness, according to scholarly consensus (Raichle, 2015).
