Consciousness is linked to neurons through various theoretical frameworks, including the Orch OR theory which posits that quantum processes within microtubules inside neurons generate consciousness [1], [2], [3]. Additionally, physicalist perspectives attempt to reduce consciousness to the firing patterns of neurons [4], [5], while other theories debate whether consciousness is dependent on the specific biological substance of neurons [6] or exists as a primitive property within them [7].

Quantum Models of Consciousness from a Quantum Information ... arxiv.org 1 fact
claimThe Orchestrated Objective Reduction (Orch OR) theory suggests that collective states of electrons inside neurons function as qubits, with objective and orchestrated collapse mediated by microtubule molecules playing a key role in the emergence of consciousness.
Quantum Approaches to Consciousness plato.stanford.edu 1 fact
claimThe Penrose-Hameroff hypothesis assumes that quantum states are coherent superpositions of tubulin states extending over many neurons, and their simultaneous gravitation-induced collapse constitutes an elementary act of consciousness.
Consciousness (Stanford Encyclopedia of Philosophy/Fall 2025 ... plato.stanford.edu 1 fact
claimPhysicist Roger Penrose (1989, 1994) and anesthesiologist Stuart Hameroff (1998) proposed a model of consciousness where consciousness arises through quantum effects occurring within microtubules, which are subcellular structures internal to neurons.
Quantum mechanics and the puzzle of human consciousness alleninstitute.org 1 fact
claimRoger Penrose and anesthesiologist Stuart Hameroff hypothesize that microtubules, which are small structures found in neurons and other cells, weave moments of 'proto-consciousness' together to form full consciousness.
Quantum Mechanics And Consciousness: The Physics Of Mind quantumzeitgeist.com 1 fact
claimThe Orchestrated Objective Reduction (Orch-OR) theory, proposed by Roger Penrose and Stuart Hameroff, suggests that consciousness arises from quantum computations occurring in microtubules within neurons.
Landmark experiment sheds new light on the origins of consciousness alleninstitute.org 1 fact
claimResearch findings indicate a functional connection between neurons in the early visual areas at the back of the brain and the frontal areas of the brain, suggesting that consciousness may be linked to sensory processing and perception rather than primarily the prefrontal cortex.
Panpsychism - Wikipedia en.wikipedia.org 1 fact
measurementMax Tegmark calculated the decoherence rates of neurons and concluded that the brain is a classical rather than a quantum system, and that quantum mechanics does not relate to consciousness in any fundamental way.
Episode 2: The Hard Problem of Consciousness – David Chalmers ... futurepointdigital.substack.com 1 fact
claimThe physicalist project is the belief held by some philosophers and scientists that consciousness can be explained by reducing it to brain activity, specifically neurons firing in particular patterns.
David Chalmers on the meta-problem of consciousness selfawarepatterns.com 1 fact
claimThe author of the source text argues that panpsychism involves an irreducible notion of consciousness, where proponents assert that consciousness in entities like neurons, proteins, molecules, atoms, or electrons is a primitive building block rather than the consciousness familiar to humans.
The Conscious Mind - Wikipedia en.wikipedia.org 1 fact
claimDavid Chalmers concludes that consciousness is realised through the structure of the brain rather than the substance of the brain, arguing that if consciousness were substance-dependent, replacing neurons with silicon chips would cause consciousness to disappear or change, which seems implausible.
