ABSTRACT Psychoactive drugs profoundly alter consciousness, but the neural mechanisms by which they do so remain poorly understood. Global workspace theory may provide a framework for investigating these mechanisms. The global workspace, a candidate neural substrate of consciousness, is a set of brain regions that integrate and disseminate information to the rest of the brain. According to a recent model, the integrators, or “gateways,” are characterized by synergistic interactions with other brain regions, while the disseminators, or “broadcasters,” exhibit redundant interactions. Here, we me

  1. Content Without Access: A Cross-Family Fleet Measurement of Global Workspace Properties in Transformer Language Models

    paper
    IIT and global workspace — title watchMichael BakerOctober 5, 2026

    Global Workspace Theory makes two separable predictions: that a limited-capacity workspace holds and broadcasts content (its content properties), and that content enters that workspace through an all-or-none competitive transition (its access dynamics). Gurnee et al. (2026) recently reported such a workspace in a frontier language model; the accompanying commentary asked whether its access is genuinely all-or-none rather than graded, whether the representations form a unified stream rather than merely a privileged set, and whether either result generalizes beyond one model family. I report a f

    [IT] Questo lavoro introduce l'Operatore di Emergenza Dinamica (⊕), un formalismo algebrico alternativo guidato dal contesto progettato per superare l'ostacolo dell'esplosione combinatoria nel calcolo del valore Phi (Φ) all'interno dell'Integrated Information Theory (IIT 4.0). Attraverso simulazioni stocastiche non lineari a 50 passi temporali che integrano attrito dissipativo e shock stocastici gaussiani, il modello dimostra l'emergere di un'omeostasi adattiva stabile e di un'emulazione dei ritmi biologici complessi direttamente a livello di operatore locale, riducendo drasticamente il sovrac

  5. Assessing the Impact of Integrated Information Systems on Operational Efficiency in Indian Salon SMEs

    paper
    IIT and global workspace — title watchB. GnanasankariOctober 15, 2026

    Over 80% of small and medium salons in India still depends on the manual ledgers and the excel sheets for billing and appointment scheduling. This leads to problems such as delays in the business operations, inaccurate GST filing and lack of visibility regarding the staff performance (FICCI, 2023). This paper presents TASA (The All-in-one Salon Assistant) a lightweight, GST compliant system. This digital system designed specifically for Indian SMEs especially for those business in the beauty industry. Qualitative field surveys along with quantitative statistical analyses were done using Python

    paper
    Panpsychism and idealism — title watchCoty Austin TroutOctober 22, 2026

    We conduct a historical and mathematical audit of the voluntarist-idealist lineage—tracing the trajectory from Arthur Schopenhauer's 1818 metaphysical voluntarism (The World as Will and Representation) to Bernardo Kastrup's contemporary rebranding, Analytic Idealism—under the strict criteria of the Triadic Coherence Invariant, R = P × I × Pr ≠ 0 (canonically isomorphic to R = Ψ × I × Π ≠ 0). We first expose the genealogical structure of the framework: how Schopenhauer projected finite, mammalian visceral urges onto Immanuel Kant's noumenal void to invent a "blind cosmic Will," and how Kastrup

    FINDING: Panpsychism debate centers on whether consciousness is fundamental physics, with quantum-information formulations (Faggin/D'Ariano) proposing a non-computational, non-material basis — but no quantitative mathematical model or testable equation emerges from these sources. | MATH: No equations, constants, or ratios are presented in any of the listed sources. The closest to formal structure is the claim of "quantum information" as foundational, but no specific Hilbert space, operator algebra, or information-theoretic measure (e.g., von Neumann entropy S = -Tr(ρ ln ρ)) is given. | CONNECT

    GENERAL PREFACE THE NATURE OF THE SOUL An Interdisciplinary Philosophical Inquiry into Consciousness, Personhood, Identity, Agency, Meaning, and the Architecture of Becoming The question of the soul is among the oldest and most persistent questions in human intellectual history. Long before consciousness became an object of neuroscience, before psychology emerged as an independent discipline, before computation provided a language for information and artificial intelligence, human beings asked what makes a living person more than a collection of physical parts. What is the principle by which a

    paper
    Hard problem and qualiaEliam RaellOctober 14, 2026

    We propose the complex Hopf fibration S¹ → S³ → S² as the natural mathematical home for a three-fold ontology of consciousness: universal (Ψ), localized (Φ), and rendering (Λ). We adopt an argument, developed by Nielsen (2026) from two axioms, charge quantization and unification, that the universal U(1)-bundle is the canonical structure for a unified theory with a quantized U(1) sector, and we take the Hopf fibration as its first non-trivial finite realization. Given this structure, we argue that the identification Ψ = total space, Φ = base, Λ = fiber is the natural one. The identification is

    paper

    Artificial intelligence research faces a critical ethical paradox: determining whether AI systems are conscious requires experiments that may harm entities whose moral status remains uncertain. Recent work proposes avoiding consciousness-uncertain AI systems entirely, yet this faces practical limitations-we cannot guarantee such systems will not emerge. This paper addresses a gap in research ethics frameworks: how to conduct consciousness research on AI systems whose moral status cannot be definitively established. Existing graduated moral status frameworks assume consciousness has already bee

    paper
    AI consciousness — focused titlesFlorentin KochMarch 29, 2026

    Research on artificial consciousness increasingly shifts evaluation from behaviour to internal architecture. Theory-based indicators are used to update probability assignments. This improves on behavioural tests but raises two distinct problems. First, these assignments cannot currently be calibrated against independently established artificial consciousness outcomes. Second, their evidential relevance is transferred from biological cases without independent support that indicator-consciousness relations remain stable across substrates. This commentary distinguishes calibration from transfer a

  12. How to Navigate Uncertainty About AI Consciousness

    paper
    AI consciousness — focused titlesDr Tom McClellandJuly 6, 2026

    Given deep uncertainty about the possibility of artificial consciousness, it is unclear how we should treat potentially sentient AI. On the one hand, we could assume insentience but risk doing terrible harms to entities that deserve moral standing. On the other hand, we could assume sentience and instead risk wasting resources on insentient machines. The intractability of questions around AI consciousness mean that this dilemma is hard to escape. I suggest a way out of that shifts from intractable questions of AI consciousness to tractable questions of AI valence. Specifically, we can assess w
