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.
The Aeon of Horus is Ending and the Elites are Nervous as their Icons are Dying 2014 04 18
I predict there is going to be a huge resurgence of interest in European indigenous spiritual traditions from Norse to Celtic/Gaelic to Slavic and so on. Millions of Europeans are going to realise that we are the victims of Christianity and New Age garbage. Their bastardised Kabbalah, the psychic force used by Crowley and the elites to cement his Aeon ...
Easter - Christian or Pagan? 2014 04 18
Contrary to popular belief, Easter does not represent the "historical" crucifixion and resurrection of Jesus Christ. In reality, the gospel tale reflects the annual "crossification" of the sun through the vernal equinox (Spring), at which time the sun is "resurrected," as the day begins to become longer than the night.
Rather than being a "Christian" holiday, Easter celebrations date back ...
Man-Made Blood Might Be Used in Transfusions by 2016 2014 04 18 Researchers in the U.K. have created the first man-made red blood cells of high enough quality to be introduced into the human body
The premise of the HBO show and book series True Blood revolves around a technological breakthrough: scientists figure out how to synthesize artificial human blood, which, as an ample new source of non-human food, allows vampires to "come ...
The Trials of the Cherokee Were Reflected In Their Skulls 2014 04 18
Researchers from North Carolina State University and the University of Tennessee have found that environmental stressors – from the Trail of Tears to the Civil War – led to significant changes in the shape of skulls in the eastern and western bands of the Cherokee people.
The findings highlight the role of environmental factors in shaping our physical characteristics.
Our Fears May Be Shaped by Ancestral Trauma 2014 04 18
Last December, an unsettling Nature Neuroscience study found that mice who were taught to associate the smell of cherry blossoms with pain produced offspring who feared the smell of cherry blossoms, even if they had never been exposed to it before. We knew that the process was epigenetic—that it was not hard-wired in the permanent genetic structure of the mouse—but ...
