WebIn the mid 1990s we published the Penrose-Hameroff theory of ‘orchestrated objective reduction’ (‘Orch OR’) which suggests consciousness arises from quantum vibrations ‘orchestrated’ in microtubules inside brain neurons, orchestrated vibrations which are proposed to interfere, ‘collapse’ and resonate across scale, control neuronal firings, and … Orchestrated objective reduction (Orch OR) is a theory which postulates that consciousness originates at the quantum level inside neurons, rather than the conventional view that it is a product of connections between neurons.
