Key points Proposes that consciousness depends on quantum coherent states supported by van der Waals electron pair couplings (London forces) in hydrophobic pockets of select brain proteins, and that anesthetics act by inhibiting electron mobility and these London forces, thereby ablating consciousness. Argues this mechanism could explain enigmatic features of consciousness such as qualia, binding, non-computability, the pre-conscious to conscious transition, and nondeterministic free will.

Abstract

1. A consensus view holds that anesthetics act by van der Waals forces in hydrophobic pockets of select brain proteins to ablate consciousness. 2. What is consciousness? Enigmatic features of consciousness (e.g. 'qualia', binding, non-computability, pre-conscious-->conscious transition, nondeterministic free will) may be explained by the occurrence of quantum coherent states in the brain. 3. Van der Waals electron pair couplings (London forces) in hydrophobic pockets in non-anesthetic (conscious) conditions are a particular type of quantum capable of supporting macroscopic quantum coherence. 4. The mechanism of anesthetics may be to inhibit electron mobility and London forces necessary for quantum states and consciousness in hydrophobic pockets of select brain proteins.
