The Hard Problem of Consciousness: Integrated Information Theory vs. Global Neuronal Workspace

Summary
AI-generated from the abstractTwo leading theories of consciousness—Integrated Information Theory (IIT) and Global Neuronal Workspace (GNW)—make competing predictions about where and when conscious activity arises in the brain. IIT points to posterior regions, while GNW implicates frontal areas. Recent adversarial collaboration testing these predictions has yielded evidence relevant to this debate. However, even with such neuroscientific advances, the philosophical 'hard problem' of why and how physical processes give rise to subjective experience remains unresolved.

Abstract
The search for the neural correlates of consciousness (NCC) is currently dominated by two competing paradigms: Integrated Information Theory (IIT) and Global Neuronal Workspace (GNW). This paper analyzes the recent 'adversarial collaboration' results that test these theories' predictions regarding the anatomical location and timing of conscious activity. We discuss the implications of finding evidence in posterior vs. frontal regions and the philosophical 'hard problem' that persists despite neuroscientific progress
