claimThe lateral prefrontal cortex (LPFC) is a key component of the fronto-parietal executive control network (FPN) and is posited to act as a global broadcaster of information within the global workspace, according to Global Neuronal Workspace Theory (GNWT).
claimGateways in the brain reside primarily in the default mode network, while broadcasters are mainly located in the executive control network, specifically the lateral prefrontal cortex.
claimThe authors of 'A Synergistic Workspace for Human Consciousness Revealed by...' assign the role of global broadcaster to the lateral prefrontal cortex (LPFC) based on its combined information-theoretic and network properties.
claimThe fronto-parietal executive control network (FPN) comprises lateral prefrontal and parietal cortices and is associated with the performance of a variety of complex, cognitively demanding tasks.
claimThe finding that the lateral prefrontal cortex acts as a major broadcaster of information aligns with Global Neuronal Workspace Theory, which consistently identifies this region as a major broadcaster.
claimSome brain connections, particularly in the frontal cortex and lateral prefrontal cortex, exhibited increases in ΦR during loss of consciousness and were restored upon recovery.
claimThe lateral prefrontal cortices are among the brain regions most closely associated with the global neuronal workspace in scientific literature.
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.

measurementExperienced meditators exhibit increased activity in prefrontal areas, specifically the lateral prefrontal cortex (PFC), during meditative states compared to non-meditators.
measurementStudies on mindfulness-based interventions (MBI) have found differences in gray matter (GM) volume and density in the orbitofrontal cortex (OFC) and lateral prefrontal cortex (PFC) in meditators compared to non-meditating controls using MRI.
claimThe human anterior insular cortex (AIC) integrates higher-order social, emotional, motivational, and cognitive components of subjective feeling states through functional and anatomical connectivity with the anterior cingulate cortex (ACC), ventral medial pre-frontal cortex (VMPFC), and lateral prefrontal cortex (PFC).
