If all matter operates in a quantum mechanical way at an atomic level, then it follows that the matter from which neurons in our brain are made of work this way too. Neurons deliver and receive messages from our brain when thoughts occur in our mind. Quantum mechanics leads to all sorts of mysterious behavior in the ways atoms behave including Heisenberg’s Uncertainty Principle which states that it is impossible to be certain of both motion and state of a quantum particle at once – or to put it another way, if we know the exact position, we can’t be certain of it’s state.
The fact these odd quantum behaviors exist in every atom, including the neurons our brains are made of, has led some to wonder if there is connection with our thoughts, quantum particles and perhaps even consciousness.
There is no scientific evidence and it is without proof but the idea of a ‘quantum mind’ is intriguing. One argument against is that the quantum effects are too minuscule in impact e.g. if you take an inanimate object and a human brain, both are quantum at the atomic scale but changes at this level makes no difference to the physical outcome. However, the idea that somehow the strange behaviors of uncertain states, entanglement (where particles are unexplainably connected together) and changing results when being observed, could be the explanation for our thoughts is not entirely out of the question, it could be connected in some way to the human unconscious and it’s sometimes irrational behavior.
