A review article suggests that there may be a third brain signaling pathway, the biofield, that scientists have been largely neglecting. The study suggests that the brain’s biofield could be influenced by quantum field theory. While previous research has shown that nervous tissue does emit biophotons via metabolic activity, the noisy environment of the brain makes the idea improbable. The researchers from Palacký University in the Czech Republic suggest that since biophots are just light emitted biologically, they theoretically possess the same quantum properties as photons. To traverse this hidden pathway of neural communication, information would need to be encoded into the quantum state of a biophoton, survive the brain's inhospitable environment, and then be decoded by the neuron. However, the study acknowledges that quantum-mediated signaling in neural tissue remains highly speculative and likely limited to very short distances.
