Is quantum mechanics involved in the human brain functions?
The Quantum Brain: Theory or Myth? Ruth Czarnecki The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function. One of the most convincing arguments of the QBT is its explanation of how reality is conceived by the brain. Classically, reality should always be changing, even by the slightest notion, and the brain should be aware of these changes as they occur. According to quantum mechanics, this wou
“The quantum mind hypothesis proposes that classical mechanics cannot fully explain consciousness, and suggests that quantum mechanical phenomena, such as quantum entanglement and superposition, may play an important part in the brain’s function, and could form the basis of an explanation of consciousness.
Yes. First of all, strictly speaking, quantum mechanics is the best description of all physical events, and that would naturally include brain function. For most things we can approximate with classical mechanics and not be far wrong. Second, quantum mechanics is necessary to describe all chemical reactions, and that would naturally include those in the brain. But the interesting question is whether quantum-mechanical phenomena show up in brain function in any larger processes than chemical reactions. All I can tell you is that in order for this to happen, the information about the process must not be allowed to escape – when information escapes, quantum coherence is lost.
