Global Neuronal Workspace Theory (GNWT) is a theoretical framework that explicitly posits how conscious experience arises from neural activity, specifically through mechanisms like 'ignition' and broadcasting {fact:1, fact:4}. The theory's predictions regarding the neural correlates of conscious experience were the subject of an adversarial study conducted by the Cogitate Consortium {fact:2, fact:3, fact:6}.

claimGlobal Neuronal Workspace Theory (GNWT) posits that prefrontal cortex workspace neurons broadcast information but do not add information to the conscious experience.
claimGlobal Neuronal Workspace Theory (GNWT) predicts brief, content-specific ignition in the prefrontal cortex within 0.3–0.5 seconds after stimulus onset, followed by a decay back to baseline where information is maintained in a latent state until another ignition marks the offset of the current percept and the onset of a new one.

claimThe Cogitate Consortium study found that while some conscious information appeared in the prefrontal cortex, the Global Neuronal Workspace Theory (GNWT) prediction of 'ignition' at the offset of conscious experience could not be confirmed.
claimThe Cogitate Consortium (Collaboration On GNWT and IIT: Testing Alternative Theories of Experience) conducted an adversarial test of the Global Neuronal Workspace Theory (GNWT) and the Integrated Information Theory (IIT) to evaluate how conscious experience arises from neural activity.
