A Synergistic Workspace for Human Consciousness Revealed by ... elifesciences.org eLife 2 facts

claimRegions showing consistent decreases in ΦR during loss of consciousness were primarily members of the global synergistic workspace, specifically the default mode network (bilateral precuneus and medial prefrontal cortex) and bilateral inferior parietal cortex, with involvement of left temporal cortices.

claimThe default mode network (DMN) comprises the posterior cingulate, precuneus, medial prefrontal cortex, and inferior parietal cortices.

claimSpeech production is compromised under LSD because of the lack of connections with the neocortical components involving the frontal lobe (Broca's area), while the language capacity for understanding meaning persists because of its lower anatomical basis near the Default Mode Network (DMN) component, the inferior parietal lobule in the superior temporal gyrus (Wernicke's area).

claimClassic psychedelics initiate a cascade of altered neural connectivity and blood-flow across brain regions including the default-mode network (medial prefrontal cortex, posterior cingulate cortex, inferior parietal lobule, lateral temporal cortex, hippocampus, and precuneus), the amygdala, the thalamus, and the claustrum.
