The prefrontal cortex is identified as a critical neural substrate for consciousness within the Global Neuronal Workspace Theory (GNWT), which posits that conscious content is encoded in the prefrontal cortex [1], [2] and maintained through its activity [3], [4].

claimRegarding the maintenance of conscious percepts over time, Integrated Information Theory (IIT) predicts that conscious content is actively maintained by neural activity in the posterior ‘hot zone’ throughout the duration of a conscious experience, whereas Global Neuronal Workspace Theory (GNWT) predicts ignition events in the prefrontal cortex (PFC) at stimulus onset and offset, with activity-silent information maintenance in between.

claimRegarding interareal connectivity during conscious perception, Integrated Information Theory (IIT) predicts sustained short-range connectivity within the posterior cortex, linking low-level sensory areas like V1/V2 with high-level category-selective areas, whereas Global Neuronal Workspace Theory (GNWT) predicts long-range connectivity between high-level category-selective areas and the prefrontal cortex (PFC).

claimIntegrated Information Theory (IIT) predicts that conscious content is maximal in posterior brain areas, whereas Global Neuronal Workspace Theory (GNWT) predicts a necessary role for the prefrontal cortex (PFC).
