It has been 175 years since William Morton demonstrated the world's first general anesthetic and called it “Ether Day.” However, the mechanism of loss of consciousness caused by general anesthetics is still shrouded in mystery. The “consciousness” lost by general anesthesia itself is complex, and it is challenging to elucidate the mechanism of action of general anesthetics. It is not easy to verify that a person is conscious or not. So, there is a possibility that there are patients in the operating room or intensive care unit who are conscious but unable to move. The discovery and invention of biomarkers that can objectively evaluate the state of consciousness of patients are expected. Through trial and error of our predecessors, our understanding of the primary mechanism of general anesthesia has been built. Recent advances in science and technology have dramatically, if not wholly, improved our understanding of the mechanism of action by which anesthetics cause loss of consciousness. In the future, elucidating the mechanism of loss of consciousness induced by general anesthetics is expected to help us understand where human “consciousness” lies. In this article, we outline the history, existing knowledge, theories, and hypotheses on the mechanism of general anesthesia.
