Possible superconductivity in brain

TL;DR

This paper explores the possibility that superconductivity exists in the brain, potentially explaining quantum processing and long-term memory, supported by recent electrical measurements and theoretical models suggesting high critical temperatures.

Contribution

It proposes that superconductivity may occur in brain microtubules, supported by recent experimental evidence and theoretical predictions of high critical temperatures.

Findings

Electrical measurements with graphene suggest superconductivity in brain tissue.

Estimated critical temperature of brain superconductivity is around 2063 K.

Theoretical models predict similar high critical temperatures in organic chains.

Abstract

The unprecedented power of the brain suggests that it may process information quantum-mechanically. Since quantum processing is already achieved in superconducting quantum computers, it may imply that superconductivity is the basis of quantum computation in brain too. Superconductivity could also be responsible for long-term memory. Following these ideas, the paper reviews the progress in the search for superconductors with high critical temperature and tries to answer the question about the superconductivity in brain. It focuses on recent electrical measurements of brain slices, in which graphene was used as a room-temperature quantum mediator, and argues that these measurements could be interpreted as providing evidence of superconductivity in the neural network of mammalian brains. The estimated critical temperature of superconducting network in brain is rather high: 2063 plus-minus 114 K. A similar critical temperature was predicted in the Little's model for one-dimensional organic chains linked to certain molecular complexes. A reasonable suggestion is that superconductivity develops in microtubules inside the neurons of brain.
