Consciousness in the universe: a review of the Orch OR theory

Hameroff, S. & Penrose, R. Physics of Life Reviews 11, 39–78 (2014).

Hameroff and Penrose review their proposal that orchestrated quantum processes in neuronal microtubules terminate through objective reduction and correspond to conscious moments.

REPORTED FINDINGS

01The paper specifies the authors’ proposed microtubule mechanism.

02It connects objective reduction to spacetime geometry and neural activity.

03It provides a concentrated statement of an influential quantum-consciousness theory.

LIMITS / CAUTION

Orch OR is controversial and empirically unsettled. A theory review states and updates a proposal; it is not independent confirmation of the mechanism.
