Directing the Laboratory for Perception and Action at the Baylor College of Medicine in Houston, Eagleman studies time, synesthesia and neurolaw.
But he’s no ordinary neuroscientist. “Sum,” his book of short stories about various afterlives, is an international best-seller, translated into 23 languages. It led to a collaboration with Brian Eno; composer Max Richter will debut a full-length work based on “Sum” next year atLondon’s Royal Opera House; and the screen rights have just been sold.
We spoke at Bloomberg world headquarters in Manhattan.
Lundborg: How is consciousness like a “tiny stowaway on a transatlantic steamship?”
Eagleman: The conscious mind is the smallest bit of what’s transpiring in the brain.
Even though we feel like we’re the ones navigating our lives, there is quite a bit about our desires, our motivations, our attractions, our hopes and our beliefs that is generated by parts of our brain that we don’t have access to and we’re not even acquainted with.
The brain is essentially this massive computational device that runs all of its operations under the hood.
Ed Note: "The brain is essentially this massive computational device that runs all of its operations under the hood." We’re automatons behaving at the whim of a fleshy blob of protein? Robotic shells with no capacity for free will? ~E
Lundborg: So many implications -- for example, you say men find women with dilated eyes more attractive without knowing why.
Eagleman: Yes. When men were shown photographs of women’s faces, the men uniformly found the women with dilated eyes more attractive.
None of the men were able to say “Oh, I noticed her pupils were a millimeter larger in this photo.” And none of the men knew consciously that dilated eyes are a sign of sexual readiness in women.
Nonetheless, their brains knew that. They have all kinds of information that their brains are picking up at a deeper level, and it drives them toward that behavior.
Lundborg: Men want full lips, full buttocks, and a narrow waist, while women a full jaw, stubble, and a broad chest.
Eagleman: These are signs that broadcast one signal: “I am fertile.” It’s not that we’re really making a choice about what we find beautiful; we have millions of years of evolution driving us towards having that conscious summary.
Lundborg: What happens to romance?
Eagleman: We feel love, but it all has to do with securing a mate and reproduction and so on, which is not to say that we can’t enjoy every bit of it. But it’s not there without purpose.
Lundborg: Do the “zombie systems” running things without any input from the conscious mind mean free will is an illusion?
Eagleman: Some scientists think so, but what I conclude is that we might have free will but it’s probably going to be a bit player in the operations of the brain.
Consciousness does seem to be useful for setting the long- term goals of the system exactly the same way that a CEO does.
Lundborg: You say we’re nearing a time when stock market data could be plugged directly into the brain. How would that work?
Eagleman: This is the subject of my next book on brain plasticity, called “Live Wired.”
The brain is this alien kind of computational device that can wrap itself around whatever inputs it has. So there’s nothing special about eyes and ears and nose. Those are just essentially peripheral plug and play devices that can send data fibers into the brain, and the brain figures out what to do with it.
You should be able to plug anything, any data cables, into the brain and it will learn how to interpret those and it will actually have perception.
Lundborg: How exactly do we plug those in?
Eagleman: Electrodes directly into the cortex, but it’s not safe yet.
Lundborg: How can science address larger business issues?
Eagleman: Your brain operates as a team of rivals. You are made up of all these competing neural networks that we can image now, these networks that are all battling it out under the hood.
This gives us a new and nuanced way of understanding how people make decisions. When we look at things like financial markets, the future of economics is agent-based modeling, where people look at how individual humans make decisions and interact with one another, combined with the diversity of human beings.
The future of economics is going to be simulating giant populations of people interacting and trading with one another, and that’s something I’m interested in doing in the future.
Agenda 21: The BLM Land Grabbing Endgame 2014 04 23 Why is the federal government so obsessed with grabbing more land? After all, the federal government already owns more than 40 percent of the land in 9 different U.S. states.
Why are federal bureaucrats so determined to grab even more? Well, the truth is that this all becomes much clearer once you understand that there is a ...
Fukushima radiation killing children, government hiding the truth 2014 04 22 Katsutaka Idogawa, former mayor of Futaba, a town near the disabled Fukushima nuclear plant, is warning his country that radiation contamination is affecting Japan’s greatest treasure - its children.
Asked about government plans to relocate the people of Fatuba to the city of Iwaki, inside the Fukushima prefecture, Idogawa criticized the move as a "violation of human rights."
Compared with Chernobyl, radiation ...
Why your fingerprints may not be unique 2014 04 22 Assumption that everyone has a unique fingerprint from which they can be identified through a computer database is flawed, says Home Office expert Mike Silverman
Fingerprint evidence linking criminals to crime scenes has played a fundamental role in convictions in Britain since the first forensic laboratory was set up in Scotland Yard in 1901.
But the basic assumption that everyone has a ...
Asteroids cause dozens of nuclear-scale blasts in Earth’s atmosphere 2014 04 22
Asteroids caused 26 nuclear-scale explosions in the Earth’s atmosphere between 2000 and 2013, a new report reveals.
Some were more powerful – in one case, dozens of times stronger – than the atom bomb blast that destroyed Hiroshima in 1945 with an energy yield equivalent to 16 kilotons of TNT.
Most occurred too high in the atmosphere to cause any serious damage ...
‘Editing DNA’ to eliminate genetic conditions now a reality 2014 04 22 Scientists have employed a revolutionary genome-editing computer technique that accurately identifies one faulty genetic “letter” among billions and effortlessly repairs a genetic condition in animals, paving way for human trials.
The success, by MIT in Boston, is the latest achievement in the field of genome editing that has been catapulted into the spotlight through a technology that can pinpoint genetic faults ...
