Abstract
Biological systems are dynamical, constantly exchanging energy and matter with the environment in order to maintain the non-equilibrium state synonymous with living. Developments in observational techniques have allowed us to study biological dynamics on increasingly small scales. Such studies have revealed evidence of quantum mechanical effects, which cannot be accounted for by classical physics, in a range of biological processes. Quantum biology is the study of such processes, and here we provide an outline of the current state of the field, as well as insights into future directions.
"Good theories" is something of an overstatement. Geometrical optics is an example of a good theory; general relativity is another. Discussions of Quantum Mind are better described as "interesting conjectures".entropy2information said:You have many good theories of a Quantum Mind
I don't think that anyone is trying to say that it is "barred". However, two different claims are often conflated in these discussions:At the end of the day, you can't say Evolution and Natural Selection are so powerful and these quantum effects are seen throughout nature adding to efficiency and advantage yet it's barred from being connected to consciousness.
Nugatory said:Penrose and others have offered up Quantum Mind ideas along the lines of #2, but nothing has moved beyond the point of interesting conjecture. There's nothing inherently wrong with this speculation, but it's hard to argue that QM will explain consciousness without actually explaining it.
Much has been made of quantum computing processes using ultracold atoms and ions, superconducting junctions and defects in diamonds, but could we be performing them in our own brains?
It’s a question UC Santa Barbara theoretical physicist Matthew Fisherhas been asking for years. Now, as scientific director of the new Quantum Brain Project (QuBrain), he is seeking to put this inquiry through rigorous experimental tests.
“Might we, ourselves, be quantum computers, rather than just clever robots who are designing and building quantum computers?” Fisher asks.
I don't think so, I think it is very unlikely.Demirci Kawa said:We need quantum physics for cognitive neuroscience ?
I think it is likely that the human species is the most self-conscious species on this planet, but I'd like to add that there are studies which have shown that a couple of other species have self-awareness (which is a part of self-consciousness), e.g. various primates, elephants, dolphins and, quite amazingly considering their relatively small size, magpies;entropy2information said:as a way to give a species (ours) a huge advantage and this huge advantage is self consciousness.
Quantum mechanics is a branch of physics that studies the behavior of particles at a very small scale. It has been suggested that certain processes in the brain, such as neurotransmitter release and neural communication, may involve quantum effects.
While there have been some studies that suggest quantum effects may play a role in brain function, the evidence is still inconclusive. More research is needed to fully understand the potential role of quantum mechanics in the brain.
Some theories propose that consciousness may arise from quantum processes in the brain. However, this is still a highly debated topic and there is no clear answer at this time.
If it is confirmed that quantum mechanics plays a role in brain function, it could potentially lead to new insights and treatments for neurological disorders. It could also contribute to the development of quantum computing technology.
One of the main challenges is that the brain is a highly complex and dynamic system, making it difficult to isolate and study specific quantum processes. Additionally, the concept of consciousness and its relationship to quantum mechanics is still not well understood, making it a challenging area of research.
