Think of the last time you were put under for an operation. The anesthetist asks you to count back from ten. You reach seven, maybe six. Then a nurse is saying your name and the clock on the wall has jumped forward by two hours.
Where were you in between?
Konstantin Anokhin, a neurobiologist, Academician of the Russian Academy of Sciences and director of the Institute for Advanced Brain Studies at Moscow State University, gives a blunt answer in the Think Like a Scientist episode with Ivar Maksutov: nowhere. You did not exist.
He says it in passing, as a stop on the way to his larger theory of the brain. He does not build a long proof. But the remark carries weight. If it is right, then your waking self is a flame that is lit again each morning, and what matters most to you is whatever keeps relighting it.
His starting point is plain. Think of everything you live through in a day: the taste of the morning coffee, the sight of an evening sunset, the sharp pain of a pebble in your shoe, a plan for tomorrow, the helpless feeling that the world is rolling off somewhere unknown. Scientists call all this subjective experience, and Anokhin notes that some philosophers call it "subjective reality". That stream of states, he says, is our existence. At least for humans, who can know it about themselves. Whether animals share it is a question he leaves for later discussion.
Then comes the step that makes people uncomfortable. If the stream is your existence, then when it stops, you stop. Dreamless sleep, a faint, anesthesia: in each of these, he says, you do not exist at that moment.
We exist only at the level of consciousness. If you imagine consciousness leaving you, even for a while, in dreamless sleep, a faint, anesthesia, at that moment you do not exist.
Мы существуем только на уровне сознания. Если вы представите себе ситуацию, когда сознание уйдёт от вас, или даже на время, сна без сновидений, обморока, наркоза, вы в этот момент не существуете.
— Konstantin Anokhin, Think Like a Scientist, 26:03
What follows is his most striking line. If you are lucky and wake up afterwards, he calls it a miracle: the miracle of you coming back.
Notice what he does not say. He does not claim that the brain is quiet during these hours. Neurons keep working. Research now suggests the picture is more complicated than "off". A study in Nature Communications in September 2024, led by Zirui Huang, found that when anesthesia takes consciousness away, the brain's large-scale pattern of activity moves from a balanced arrangement of two cell systems, called core and matrix, to one where the matrix part is lacking. And a paper in Nature in May 2026, by Kalman Katlowitz and colleagues, reports that under general anesthesia people's brains kept noticing odd sounds, processing meaning and predicting what would come next. So the machinery can keep running while the person is gone. Anokhin's claim concerns the person, the one who feels, not the tissue.
That distinction is why he cares. In his view, science has a job to do here, and it is odd: to derive from scientific data something every human already knows. What does it mean to exist inside a conscious body, and how does that differ from the existence of a plant? What appears in creatures that can feel which is missing from stones, mountains, trees and rivers? He wants this treated as a physical fact, something a theory must make "absolutely transparent".
His own theory, the cognitome theory, does not attack that question head-on. Anokhin's bet is that you cannot understand consciousness by staring at consciousness. It is a process, a flow, and a process only makes sense inside a system that produces it. No subject, no subjective experience. So he starts from the system: the kind of thing about which we ask "who?" rather than "what?". Consciousness, for him, arrives later, as a consequence.
There is a quiet detail in this that is easy to miss. When you fall asleep and the flow stops, something does not go away. He says the structure remains, and when you wake you return to it, "because it has not gone anywhere". The stream is what switches off. The system that can make it again stays put.
So tonight, when you drift off, what goes dark is not just your day. By his account, it is you. What brings you back at dawn is the one thing he is most interested in, and the one thing the flame itself cannot explain.
