Guides
In-depth guides to theories of consciousness, research methods, and key topics in consciousness science.
Theories
Attention Schema Theory (AST)
Michael Graziano's theory that consciousness is the brain's simplified model of its own attention process.
Bioelectricity and Consciousness
Michael Levin's research on bioelectric networks as a medium for cognition and goal-directed behavior in all living systems.
Enactivism
Thompson and Varela's framework proposing consciousness emerges through an organism's active engagement with its environment.
Global Workspace Theory (GWT)
Bernard Baars' cognitive architecture where consciousness emerges from information broadcast across the brain.
Higher-Order Theories of Consciousness (HOT)
Rosenthal and Lau's framework proposing consciousness requires higher-order mental representations about our own mental states.
Idealism in Philosophy of Mind
Bernardo Kastrup's analytical idealism and the philosophical tradition arguing consciousness is fundamental, not matter.
Illusionism
Keith Frankish and Daniel Dennett's view that phenomenal consciousness is an introspective illusion, not a real property of experience.
Integrated Information Theory (IIT)
Giulio Tononi's mathematical framework proposing consciousness arises from integrated information.
Neural Correlates of Consciousness (NCC)
The search for the minimal neuronal mechanisms jointly sufficient for any one specific conscious percept.
Neurophenomenology
Francisco Varela's research program integrating first-person experiential reports with third-person neuroscience.
Orchestrated Objective Reduction (Orch OR)
Penrose and Hameroff's quantum theory proposing consciousness arises from gravitational self-collapse in neuronal microtubules.
Panpsychism
The view that consciousness is a fundamental and ubiquitous feature of the physical world.
Quantum Consciousness
The controversial hypothesis that quantum processes in the brain play a role in conscious experience.
Recurrent Processing Theory (RPT)
Victor Lamme's theory that consciousness arises from recurrent neural processing, not feedforward activity.
The Free Energy Principle
Karl Friston's framework proposing that all living systems minimize surprise through predictive processing.
The Hard Problem of Consciousness
David Chalmers' formulation of why subjective experience cannot be explained by physical processes alone.
Topics
AI Consciousness
The question of whether artificial intelligence systems can have subjective experience.
Anesthesia and Consciousness
How general anesthesia illuminates the neural mechanisms of consciousness by selectively abolishing awareness.
Animal Consciousness
From the Cambridge Declaration to octopus cognition — the science and ethics of non-human conscious experience.
Consciousness and Death
Terminal lucidity, cardiac arrest studies, and near-death experiences — what dying reveals about consciousness.
Meditation and Consciousness
How contemplative practice and neuroscience intersect to reveal the nature of conscious experience.
Near-Death Experiences
Scientific investigation of conscious experience during clinical death and its implications.
Plant Consciousness
Stefano Mancuso, plant intelligence, and the controversial question of whether plants have any form of awareness.
Psychedelics and Consciousness
How psilocybin, DMT, and LSD research is transforming our understanding of conscious experience.
Sleep and Consciousness
How sleep stages, dreaming, and sleep deprivation reveal the nature and mechanisms of conscious awareness.
Comparisons
Bottom-Up vs Top-Down Approaches to Consciousness
Neuroscience-first vs philosophy-first: which direction leads to understanding consciousness?
Dualism vs Physicalism
Descartes' two-substance view against modern physicalism: is mind separate from body?
Eastern vs Western Approaches to Consciousness
Buddhist and Hindu contemplative traditions compared with Western analytical philosophy and neuroscience.
Functionalism vs Phenomenology
Is consciousness defined by what it does (function) or what it is like (experience)?
Hard Problem vs Easy Problems of Consciousness
David Chalmers' foundational distinction between explaining function and explaining experience.
IIT vs Global Workspace Theory
Comparing the two dominant scientific theories of consciousness: Integrated Information Theory and Global Workspace Theory.
Materialism vs Idealism
The fundamental ontological divide: is matter primary, or is mind?
Panpsychism vs Emergentism
Does consciousness go all the way down to fundamental particles, or does it emerge only from complex systems?
Reductionism vs Holism in Consciousness Studies
Can consciousness be fully explained by reducing it to its parts, or must it be understood as an irreducible whole?
Science vs Contemplative Practice
Can consciousness be measured from the outside, or must it be explored from within?
