related 3.91 — strongly supporting 14 facts
The relationship is defined by the Orchestrated Objective Reduction (Orch OR) hypothesis, which posits that consciousness arises from quantum computations or state reductions occurring within microtubules {fact:1, fact:3, fact:7}. Researchers like Roger Penrose and Stuart Hameroff have extensively argued that these subcellular structures serve as the biological site for the emergence of consciousness {fact:2, fact:6, fact:8, fact:9}.

Quantum Approaches to Consciousness plato.stanford.edu 2 facts
claimRoger Penrose and Stuart Hameroff have argued that microtubuli are the biological structures where gravitation-induced quantum state reductions related to consciousness might occur.
claimRoger Penrose and Stuart Hameroff argue that elementary acts of consciousness are non-algorithmic (non-computable) and are neurophysiologically realized as gravitation-induced reductions of coherent superposition states in microtubuli.

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.
Consciousness-Induced Quantum State Reduction - Nova Spivack novaspivack.com 1 fact
claimPenrose (1989) and Hameroff & Penrose (2014) proposed biophysical models linking consciousness to objective collapse mechanisms involving microtubules, though Tegmark (2000) challenged these models regarding biological feasibility and experimental verification.

perspectiveAnil Seth argues that simulating biological details, such as mitochondria or microtubules, in a digital computer does not make the simulation conscious unless consciousness is constitutively computational.
Quantum Approaches to Consciousness plato.stanford.edu 1 fact
claimAfter more than three decades, the Penrose-Hameroff approach has inspired research into quantum effects on consciousness across various theoretical and empirical groups, covering areas from microtubuli to synaptic processes and large-scale brain regions.
Quantum Approaches to Consciousness plato.stanford.edu 1 fact
claimRoger Penrose and Stuart Hameroff developed a scenario claiming that quantum theory is effective for consciousness, specifically arguing that elementary acts of consciousness are non-algorithmic and neurophysiologically realized as gravitation-induced reductions of coherent superposition states in microtubuli.

claimDavid Chalmers notes that Stuart Hameroff and Roger Penrose's work clarifies that they view consciousness as fundamental, rather than explaining it wholly in terms of quantum action in microtubules.
