The prefrontal cortex contributes to metacognition and report but appears less central for raw phenomenal experience. Evidence from patients with posterior damage supports this division, showing that awareness can persist even when frontal systems are intact.
Global Neuronal Workspace: How Signals Gain Conscious Access in the Brain
The theory introduces a measure called phi, which quantifies the amount of integrated information. The shift from nonconscious to conscious often aligns with the moment when a signal gains global access rather than when it first appears in sensory areas.
Dopamine links prediction errors to salience, determining which stimuli break into conscious focus. Anesthetic agents target these systems, shifting the brain from conscious to unconscious states.
Global Neuronal Workspace and the Brain's Hot Zone for Consciousness
When these areas are active, awareness is likely present; when they are silenced, as in deep anesthesia, consciousness fades. This hot zone includes the parietal, temporal, and occipital association areas, excluding primary sensory regions.
