A Cognitive Theory of Consciousness
Consciousness functions as a "global workspace" — unconscious specialized processors compete for access; the winners broadcast their content globally, making it conscious. Theatre metaphor: bright …
A Default Mode of Brain Function
Identified a set of brain regions (mPFC, PCC/precuneus, angular gyri, MTL) consistently more active during passive rest than during task performance. This "default mode" correlates with …
Alterations in Brain and Immune Function Produced by Mindfulness Meditation
8-week MBSR increased left-sided anterior activation (positive affect) and antibody response to flu vaccine in healthy adults. Effect size correlated with meditation practice time.

Could a Large Language Model Be Conscious?
Applies theoretical frameworks (GWT, IIT, HOT, AST) to LLMs. If functionalism is true, nothing rules out LLM consciousness in principle. Current LLMs likely fall short on integration, embodiment, and …
Detecting Awareness in the Vegetative State
A patient diagnosed as vegetative was instructed to imagine playing tennis (activates SMA) and walking through her home (activates parahippocampus, etc.). Brain activity was indistinguishable from …
Divided Consciousness: Multiple Controls in Human Thought and Action
"Hidden observer" monitors experience while hypnotized subject is unaware. Executive ego delegates control to subsystems. Hypnosis involves a dissociation of executive control functions.
Epiphenomenal Qualia
Mary knows everything physical about colour vision but has lived in a black-and-white room. Upon seeing red for the first time, she learns something new — therefore physicalism is false. Qualia are …
Facing Up to the Problem of Consciousness
Distinguishes the "easy problems" (explaining cognitive functions) from the "Hard Problem" (explaining why there is subjective experience at all). Consciousness does not logically supervene on the …
Five Levels of Self-Awareness as They Unfold Early in Life
Five levels: (0) Differentiation — self/world at birth; (1) Situation — body in place (~2mo); (2) Identification — own body as special (~6mo, mirror self-exploration); (3) Permanence — self as …
Flow: The Psychology of Optimal Experience
Nine dimensions: challenge-skill balance, merging action-awareness, clear goals, immediate feedback, concentration, paradox of control, loss of self-consciousness, time distortion, autotelic …
Galileo's Error: Foundations for a New Science of Consciousness
Galileo's "error" was excising consciousness from the scientific worldview by decreeing that only quantities (shapes, sizes, motions) count as real, while qualities (colours, sounds, tastes) are …
General Anesthesia and the Neural Correlates of Consciousness
Reviews how anaesthetics disrupt corticocortical and thalamocortical integration. Links anaesthetic mechanisms to IIT (integration disruption) and GNW (frontoparietal decoupling). Anesthesia = …

Lucid Dreaming Verified by Volitional Communication During REM Sleep
Subjects used pre-arranged eye movement signals during REM sleep to indicate they knew they were dreaming, proving that lucid awareness occurs during genuine REM sleep.
Materialism and Qualia: The Explanatory Gap
Even if mental states = brain states is true, we cannot explain *why* or *how* this identity holds. The explanatory gap is the cognitive chasm between physical descriptions and phenomenal character.
Meditations on First Philosophy
Cogito ergo sum — the one indubitable fact is that I am a thinking thing. Mind (res cogitans) and body (res extensa) are distinct substances. The pineal gland mediates interaction. Establishes the …
Mind in Life: Biology, Phenomenology, and the Sciences of Mind
Extends the enactive approach: life and mind share a set of basic organizational principles (autopoiesis, sense-making, precarious autonomy). Consciousness emerges not from neural activity alone but …
Minds, Brains, and Programs
If a person follows a rule-book to simulate Chinese conversation, they don't understand Chinese. Similarly, a program executing symbol-manipulation has no understanding, semantics, or consciousness — …
Mulamadhyamakakarika (Fundamental Verses on the Middle Way)
All phenomena, including consciousness itself, are empty (sunya) of intrinsic existence. Emptiness is not non-existence but dependent origination (pratityasamutpada). The self is not found in the …

Perturbational Complexity Index (PCI)
TMS-EEG measures brain response to direct perturbation. Conscious states (wake, dreaming, MCS) produce differentiated + integrated complex patterns. Unconscious states (VS/UWS, deep sleep, propofol) …
Phenomenology of Perception
Consciousness is inherently embodied — the "lived body" (corps vécu) is the subject of perception, not an object among objects. Perception is primary; intellectual reflection is derivative. Habit, …
Process and Reality
Reality consists of "actual occasions" — drops of experience — that prehend each other. Every actual entity is a subject experiencing its concrescence. God is the primordial nature that envisions all …
Psilocybin Can Occasion Mystical-Type Experiences Having Substantial and Sustained Personal Meaning and Spiritual Significance

Shadows of the Mind: A Search for the Missing Science of Consciousness
Refines the Gödelian argument and proposes microtubules (cytoskeletal proteins) as the site of quantum computation in neurons. Orchestrated Objective Reduction (Orch-OR) = quantum coherence in …
Subjective Consciousness: A Self-Representational Theory
A conscious state is one that represents itself in the right way. The subjective character of experience (its "for-me-ness") is explained by a state's self-representation. Integrates phenomenological, …
Superintelligence: Paths, Dangers, Strategies
Intelligence is orthogonal to goals — a superintelligent AI can pursue any goal, not necessarily human-aligned ones. Consciousness is a separate question from intelligence. The "control problem" of …
Tantraloka (Light of the Tantras)
Encyclopedic work systematizing Trika Shaivism. Consciousness = Prakasha (light/stasis) + Vimarsha (reflective awareness/dynamism). The universe is the *spanda* (creative vibration) of absolute …
The Analysis of Matter
Physics reveals only the *relational structure* of matter, not its intrinsic nature. The intrinsic nature of the physical world may be something akin to percepts or mental events. Consciousness is not …
The Ancient Origins of Consciousness: How the Brain Created Experience
Consciousness originated in Cambrian vertebrates (~520M years ago) with image-forming eyes, complex motor systems, and integrated sensory-motor coordination. Midbrain/brainstem origin, not neocortex. …
The Bhagavad Gita
Krishna's discourse to Arjuna on the battlefield. Three paths to liberation: karma yoga (detached action), bhakti yoga (devotion), jnana yoga (knowledge). The cosmic vision (Vishvarupa) reveals …
The Brain as a Dream State Generator: An Activation-Synthesis Hypothesis of the Dream Process
Dreams = cortex's attempt to synthesize random brainstem PGO signals. No disguised meaning or Freudian symbolism — dreams are the brain's best effort to make sense of internally generated signals.
The Cambridge Declaration on Consciousness (2012)
"Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states." Named mammals, birds, and octopuses. Rejected the …
The Conscious Mind: In Search of a Fundamental Theory
Book-length development: consciousness is a fundamental feature of the world (like mass or charge). Psychophysical laws connect physical processes to conscious experience. Explores panpsychism, …
The Embodied Mind: Cognitive Science and Human Experience

The Emperor's New Mind: Concerning Computers, Minds, and the Laws of Physics
Gödel's incompleteness theorem proves human mathematical understanding is non-computational. Therefore consciousness cannot be captured by any algorithmic/Turing machine. Quantum gravity (objective …
The Entropic Brain: A Theory of Conscious States Informed by Neuroimaging Research with Psychedelic Drugs
Proposes the psychedelic state = increased entropy of brain signals (measured by Lempel-Ziv complexity). Primary states (psychedelics, dreaming, early psychosis) = high entropy; secondary states …
The Feeling of What Happens: Body and Emotion in the Making of Consciousness
Three layers: proto-self (neural map of body state in brainstem), core consciousness (feeling of proto-self modified by interaction with object), extended consciousness (autobiographical self). …

What Is It Like to Be a Bat?
An organism has conscious mental states iff there is something it is *like* to be that organism. Subjective character cannot be captured by any objective, third-person reduction. The bat's sonar-based …
Wholeness and the Implicate Order
Reality has two orders: the implicate (enfolded, non-local, quantum) and the explicate (unfolded, local, classical). Consciousness is not separate from matter but is a projection of the implicate …
Yoga Sutras of Patanjali
Yoga = cessation of mental modifications (citta-vritti-nirodhah). Pure consciousness (purusha) is the eternal witness, distinct from material nature (prakriti). Eight limbs: yama, niyama, asana, …
