A review article highlights growing research around the speculative hypothesis that the brain’s biofield—the electromagnetic field generated by neurons and mediated by biophotons—could be leveraging aspects of quantum field theory. Case in point: a new review article suggests that there might be a third brain signaling pathway, dubbed the biofield, that scientists have been largely neglecting. Scientists like Stephen Hawking have argued that integrating quantum field theory into neuroscience is a kind of Holmesian fallacy in which two scientific mysteries—consciousness and quantum field theory—somehow make a scientific certainty in the form of quantum consciousness. Yet scientists have also found it impossible to fully solve the conundrum of consciousness by relying on neurons alone. “By integrating sensitive biophoton detection with advanced biophysical techniques and computational modeling, the research area can begin to critically test the central hypotheses.”
