claimCorrelations between anticorrelated brain networks during meditation may indicate increased integration and volitional control in recruiting networks when contextually appropriate.
referenceBressler and Menon (2010) identified emerging methods and principles regarding large-scale brain networks in cognition.
measurementCorrelations between anticorrelated brain networks are stronger during Focused Attention (FA) meditation and smaller during Open Monitoring (OM) forms of practice.
claimThe S-ART framework is based on existing brain networks that support systems of self-processing, which are proposed to be subject to modulation through specific mechanisms cultivated by mindfulness-based meditation practices.

measurementIn a study of 15 subjects (5 females), psilocybin was shown to increase the repertoire of brain functional network states, brain integration, and neural signal complexity, resulting in an enriched state of consciousness.
referencePreller et al. (2019) published 'Effective connectivity changes in LSD-induced altered states of consciousness in humans' in PNAS, detailing how LSD impacts brain connectivity and consciousness.
referenceThe study 'Dynamical exploration of the repertoire of brain networks at rest is modulated by psilocybin' was published in Neuroimage in 2019, reporting that psilocybin modulates the dynamical exploration of brain networks at rest.

claimCorrelations between scales of mystical experience and altered states of consciousness with changes in brain connectivity during psychedelic sessions suggest the neurological mechanisms producing these phenomenal experiences.
claimPsychedelics increase functional connectivity between normally disconnected brain networks, which contrasts with their acute effect of reducing functional connectivity within the Default Mode Network.
