Bruce Gordon on the Meaning of Neuroscience (Part III)

In this third and final episode with Dr. Bruce Gordon, host Michael Egnor picks Gordon’s brain on the overlaps between historical metaphysical perspectives and modern neuroscience. What does St. Thomas Aquinas have to say about metaphysical realities, and how does that compare to Plato’s idealism? Who is right? And what can near-death experiences and other phenomena tell us about the…

Boy Born With 2% of Brain “Does Maths, He Loves Science”

Noah Wall’s story raises intriguing questions about the relationship between the brain and the mind

Well before Noah Wall was born, his odds did not look very good. Scans showed he had developed a cyst which was destroying his brain, along with spina bifida and hydrocephalus. Doctors predicted he would likely never talk, walk, or eat on his own. Five times his parents, Michelle (Shelly) and Rob, were pressed to abort him. Shelly recalls, “It wasn’t until around the 12 week scan that they knew something just wasn’t quite right,” Shelly told The Epoch Times in a video interview. “I said, ‘Does the baby have a heartbeat?’ And they said, ‘Yes.’ And I said, ‘Well, that’s all that matters to us.’” Shelly and Rob were referred to the RVI Hospital in Newcastle, where their baby…

Why a “Budding” Neuroscientist Is Skeptical of Brain Scans

After reading her perceptive essay about the problems in fMRI imaging in neuroscience, I’m sad that a gifted student has doubts about a career in the field

Kelsey Ichikawa has just published a superb essay about the pitfalls of functional magnetic resonance imaging (fMRI) of the brain. Ms. Ichikawa (pictured), who describes herself as a ”budding” neuroscientist who graduated last year from Harvard, discusses the snares into which misinterpretation can lead us. fMRI brain scanning is a relatively new technology in which researchers and clinicians use magnetic resonance images (MRI) of the brain to detect brain activity almost as it happens. The technique is widely used, both for clinical care of patients (neurosurgeons use it to map sensitive parts of the brain prior to surgery) and for research purposes. A major thrust of neuroscience research in the last couple of decades has been the use of fMRI…

Physician Explains Why He Takes Near-Death Experiences Seriously

Near-death experiences don’t fit easily into traditional science categories because they occur — often with life-changing effects — when the brain is damaged or unconscious

Health and science writer Markham Heid recounts a story from psychiatrist Bruce Greyson’s book After (2021) that typifies the near-death experiences (NDEs) that have excited research interest: The truck driver’s story sounded far-fetched. The man claimed that in the middle of his quadruple bypass heart surgery — during which he was fully anesthetized and his eyes were taped shut — he had “come to” and found that he was looking down at his own body and the doctors preparing to operate on it. He described the scene in detail, and he recalled that his surgeon had waved his elbows in the air as if he were mimicking a bird flapping its wings. Later, when asked about his patient’s peculiar account,…

A Reader Asks: Does Neuroscience Disprove Free Will?

Materialists sometimes misrepresent the evidence for free will, especially Benjamin Libet’s work

Here’s the question: I have a question regarding free will. Sam Harris in his interview with Dan Dennett said that “If we decide to do go to somewhere we experience it later but our brain decided it much earlier than our experience to this decision. If we scan the brain at that time we will tell you before you came to know” Now it raise a question because we decide through intellect. You said that free will is due to intellect so intellect is challenged here. It’s an excellent question. The answer in brief is that we most certainly do have free will. We can see this from three perspectives: scientific, philosophical, and logical. The scientific evidence The scientific evidence…

Psychologist: Consciousness Is Not a Thing But a Point of View

Mark Solms attempts to explain consciousness in his new book, Hidden Spring

Anyone who thinks about consciousness soon realizes that it is a Hard Problem. It means being a subject of experience, rather than an object to which experiences happen. A dog has consciousness. He yelps when in pain. But a rock does not care about becoming sand. In an interesting article in Psychology Today, neuropsychologist Mark Solms outlines some thoughts from a book he has written on the subject, The Hidden Spring: A Journey to the Source of Consciousness (Norton, 2021): Physiological processes do not produce consciousness in the sense that the liver produces bile. Consciousness is not a thing but rather a point of view. What we perceive objectively as physiological processes in the brain we perceive subjectively as conscious…

Why Consciousness Shows That Materialism Is False

The mind refutes materialism in a rather straightforward way

My friend and colleague Bill Dembski, a leading advocate of intelligent design of the universe and life forms, has done a superb short interview with Robert Lawrence Kuhn on Closer to Truth. Bill takes a position that will surprise many fellow Christians—he doesn’t believe that consciousness represents an insurmountable challenge to materialism: Bill makes the point that much of the popular argument hinges on shifting meanings of “materialism” and “consciousness.” By contrast, he argues, the design inference in biology is a much more effective challenge to materialism. I agree that design in nature is an effective challenge to materialism. But I also believe that the mind refutes materialism in a rather straightforward way—and in much the same way that evidence…

Can We Find Purpose in a Universe With No Underlying Purpose?

That’s the ambitious goal of a prominent science writer

British science writer Philip Ball offers us a guide to a very interesting project: an attempt to “naturalize” the idea of agency, that is, make the desire to do things—the mouse’s desire to escape the cat— explainable from a fully materialist perspective. That’s much harder than it seems. Rocks don’t desire anything. So we can’t just start from the bottom. It’s also not enough to say that the mouse wants to avoid getting killed. That’s true but it doesn’t really explain anything. For example, a person looks both ways before crossing the street to avoid getting run over. But, by itself, that doesn’t explain why she tries to avoid getting run over. One must factor in her memory, background knowledge,…

An Old Rat With No Brain Raises Some Very Interesting Questions

The researchers had no idea how strange their lab rat was until, in a routine procedure, they scanned its head

Yes, R222 was only a rat. A rat that turned out to have no brain. But here’s the thing: R222 had lived a normal life as a lab rat for two whole years. According to rat specialists, that’s like 70 human years. Researchers were, to say the least, puzzled. The story begins with a scientist scanning the brains of “very old” lab rats as part of a study on aging. Except that subject R222, otherwise a conventional rat, didn’t seem to have a brain. The brain cavity had collapsed and filled with fluid (hydrocephalus). We can see from the photo that where the control rat has brain, R222 has fluid: On further investigation, researchers found that all brain functions had…

A Neuroscientist on Why We Can Build Human-like Brains

Manuel Brenner, a particle physicist as well as a neuroscientist, thinks pattern recognition is the answer

Manuel Brenner, a particle physicist who became a theoretical neuroscientist, made the argument last year that human intelligence is less complex than we make it out to be. Thus, building an artificial intelligence might be easier than we suppose. He offers some intriguing arguments and here are some responses: ➤ Is the information we need for building human-like AI in our genes? He doesn’t think so because a tomato has 7000 more genes than a human being. Further, our human genome offers only 25 million bytes of information for our brain’s design but there are 1015 connections in the adult neocortex. His conclusion? “there needs to be a much simpler, more efficient way of defining the blueprint for our brain…

The Brain Is Not a Computer and Big Data Is Not a Big Answer

These claims are mere tales from the AI apocalypse, as George Gilder tells it, in Gaming AI

In Gaming AI, George Gilder (pictured) sets out six assumptions generally shared by those who believe that, in a Singularity sometime soon, we will merge with our machines. Some of these assumptions seem incorrect and they are certainly all discussable. So let’s look at the first two: • “The Modeling Assumption: A computer can deterministically model a brain.” (p. 50) That would be quite difficult because brains don’t function like computers: As neuroscientist Yuri Danilov said last year, “Right now people are saying, each synoptical connection is a microprocessor. So if it’s a microprocessor, you have 1012 neurons, each neuron has 105 synapses, so you have… you can compute how many parallel processing units you have in the brain if…

Are Our Minds Just an Extension of the Minds of Our Cells?

A prominent philosopher and a well-known biologist make the case, offering an illustration

Naturalism, the idea that physical nature is all there is, can lead us down some strange paths. In the words of prominent philosopher Daniel Dennett and prominent biologist Michael Levin, both of Tufts University, the road to “biology’s next great horizon” is the attempt to “understand cells, tissues and organisms as agents with agendas (even if unthinking ones).” They think that the principle of natural selection acting on random mutations can create everything, including minds: Thanks to Charles Darwin, biology doesn’t ever have to invoke an ‘intelligent designer’ who created all those mechanisms. Evolution by natural selection has done – and is still doing – all that refining and focusing and differentiating work. We’re all just physical mechanisms made of…

Can We Make Brains in a Dish? Can We Make MINDS in a Dish?

Experiments with brain organoids have left many wondering whether we should be concerned about creating brains-in-a-dish

In a recent report, Nature addressed several studies on disembodied brains grown in the lab. One of those studies, published last year by Alysson Muotri of the University of California, San Diego, showed that brain organoids (organized clusters of brain cells) displayed electrical signals reminiscent of a twenty-five-week-old pre-term baby. the electrical activity continued for several months until the experiment was eventually stopped. Experiments with such brain organoids have left many wondering whether we should be concerned about creating brains-in-a-dish. Organoids, such as those made of kidney or liver cells, have been used to study drug development and disease. They are made either from embryonic stem cells—an ethically problematic source because they involve the destruction of an embryo—or induced pluripotent…

Paralyzed Subject Gains Control Much Faster via a New Technique

The earlier technique for controlling a cursor through brain-computer interface worked but it required constant relearning

Researchers at the University of California, San Francisco, have enabled a participant who is paralyzed in all four limbs to control a computer cursor, using only brain activity, by tapping into the brain’s own natural learning system. Without tapping into that system, brain-computer interface (BCI) needs extensive daily retraining in order to work. “It’s like asking someone to learn to ride a bike over and over again from scratch,” said study senior author Karunesh Ganguly, MD, PhD, an associate professor of in the UC San Francisco Department of Neurology. “Adapting an artificial learning system to work smoothly with the brain’s sophisticated long-term learning schemas is something that’s never been shown before in a paralyzed person.” Nicholas Weiler, “First ‘Plug and…
