| Key points | The author argues that phenomenal consciousness corresponds to a stable topography of 58-65 refused synaptic transmission failures per gamma cycle in the dorsal anterior cingulate cortex and extended self-monitoring network, while access consciousness remains fully explained by the Global Neuronal Workspace. The author contends this framework accounts for vivid dreaming despite reduced P3b, subjective fading under sub-anaesthetic ketamine and dACC theta-burst stimulation with preserved reportability, and attenuated phenomenal intensity after focal ACC lesions, and proposes nine near-term double dissociations. |
Abstract
Abstract Thirty years after Ned Block’s (1995) distinction between access and phenomenal consciousness, no leading neuroscientific theory (Global Neuronal Workspace, Integrated Information Theory, Higher-Order Thought, Recurrent Processing Theory) has provided a biologically implemented mechanism unique to “what it is like”. Refusal Workspace Theory (RWT) resolves this asymmetry without altering the Global Neuronal Workspace (GNW), which remains the complete explanation of access consciousness (sustained thalamo-cortical ignition > 200 ms + P3b).Phenomenal consciousness is identified instead with the reproducible, low-entropy topography of 58–65 synaptic transmission failures per gamma cycle (~40 ms) that are systematically refused forward transmission within dorsal anterior cingulate cortex (dACC) and the extended self-monitoring network (rostral PFC, anterior insula, thalamic reticular nucleus). Human intracranial recordings already reveal trial-to-trial reliability of these failure patterns of 0.85–0.91 in no-report paradigms (Inman et al., 2023), far exceeding sensory cortices. This stability yields an analytically derived phenomenal compression index I ≈ 36.2 ± 3.1 bits (95 % CI [33.1, 39.3]; Waterman, 2025a).RWT is currently the only framework that fully preserves three decades of GNW empirical success, supplies a dedicated physical mechanism unique to phenomenal consciousness (structured refusal in negative space), and derives nine sharp, near-term double dissociations that no competitor can accommodate without fundamental revision — most crucially the topologically inverse refusal patterns that enforce mutually exclusive colour qualia (redness ≠ greenness). Key phenomena explained include vivid dreaming despite reduced P3b, subjective fading under sub-anaesthetic ketamine and dACC theta-burst stimulation while reportability is preserved, and markedly attenuated phenomenal intensity after focal ACC lesions despite intact access consciousness.This preprint is accompanied by two open-access companion papers containing full mathematical derivations, Monte-Carlo simulations, pilot EEG validation, and colour-opponency refusal-mask code: Waterman (2025a).
