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).

Fame in the Brain—Global Workspace Theories of Consciousness psychologytoday.com 3 facts
referenceHigher-Order Theories (HOT) and Global Neuronal Workspace Theory (GNWT) both posit that the prefrontal cortex (PFC) plays a central role in consciousness. However, HOT posits that the PFC's role is to generate a second-order, metacognitive representation of a first-order state (such as one generated by the primary sensory cortex), making the PFC the ultimate source of consciousness. In contrast, GNWT associates consciousness with the function of global broadcasting, whereas HOT does not assign a clear function to consciousness.
claimGlobal Neuronal Workspace Theory (GNWT) explains 'conscious access' and how consciousness relates to attention and working memory.
referenceMajor theories of consciousness, including Higher-Order Theories (HOT), Global Neuronal Workspace Theory (GNWT), Integrated Information Theory (IIT), and Recurrent Processing Theory (RPT), suggest that neural feedback or recurrent processing mechanisms are necessary for consciousness. These mechanisms originate from different areas depending on the theory: higher-order areas for HOT, the global workspace for GNWT, the posterior hot zone for IIT, and local sensory areas for RPT.

claimGlobal neuronal workspace theory predicts that a process of “neural ignition” accompanies both the start and end of a stimulus, and that it should be possible to decode the content of a person's consciousness from activity in their prefrontal cortex.
claimGlobal neuronal workspace theory faces challenges because not all contents of consciousness are decodable from the prefrontal cortex, and researchers failed to observe neural ignition when the stimulus was first presented.
