Artificial Intelligence Is Nothing Like a Brain — or a Mind

Neurons share basic mechanisms, but almost all other features vary both between types of neurons and individual ones

The brain can be modeled as a computer, but that does not mean that thought is computation. AI is human intelligence, disguised and leveraged by computation.

Here’s Neurosurgeon Mike Egnor on Sean McDowell’s Show

With a couple of revealing excerpts from the transcript

The soul can seem a bit of a mystery because the popular idea of the soul, as a sort of “ghost” is not the traditional philosophical (or Christian) one.

Brain vs. Mind: A Very Revealing Fact About Epileptic Seizures

I have treated thousands of patients with epilepsy. Seizures can result in a variety of unexpected behaviors and emotions. But let me tell you what they DON’T do…

The fact that seizures never result in abstract reasoning implies our reason is not a material power of the body but an immaterial power of the spiritual soul.

Why Much Current Consciousness Research Is a Fool’s Errand

The inability to even define consciousness with clarity is emblematic of the conceptual mess that modern neuroscience has become

Consciousness is like contact lenses. It is the means by which we experience, not what we experience. Thus we can’t “find” it in the brain.

How Logic Can Show That Your Mind Is Not Just Your Brain

A principle of physics — the indeterminacy of matter — precludes brain states from forming the basis of abstract thought

In addition to the massive evidence from neuroscience that the intellect is an immaterial power of the mind, simple logic points to the same truth.

What Did the Multi-Year Consciousness Study Really Find?

Surprisingly, the joint research teams found that the prefrontal cortex, the “personality center,” may not be as important for consciousness as we think

The demotion of the prefrontal cortex in consciousness is remarkable in the light of other researchers’ view that it is practically what makes us human.

Are People in a Persistent Vegetative State Mindless? Maybe Not

They often can and do think. Research in the area helps us understand the relationship between the mind and the brain better

While none of this research is decisive, the materialist paradigm is challenged by awareness in PVS. The dualist perspective better fits the evidence.

Does Our Humanity Really Depend on “Concept Cells”?

A recently discovered type of brain cell, thought to be unique to humans, codes for a variety of types of information around a single concept

It’s a lot to ask of one type of cell, however unique, that it be what makes humans more intelligent than chimpanzees and that it create language.

A Neurosurgeon Makes the Neuroscience Case for Free Will

Michael Egnor is concerned about the serious social implications of denying free will

Insisting that there is no free will amounts to declaring “I’m a meat robot, so take seriously what I’m saying.” That’s self-refuting nonsense, Dr. Egnor says.

The Nearly Unfathomable Complexity of Even a Mouse’s Brain

Mapping a small part of a mouse's brain required 1.6 petabytes of data, which is equivalent to 22 years of nonstop high-definition video

If it takes a hundred scientists to map a cubic millimetre of a mouse’s brain, even the material world — never mind the immaterial world of the mind — is not likely to have a simple explanation.

Scientists Dare To Hint That the Mind Can’t Just Be the Brain

They start with astonishing facts about the brains of caterpillars and worms and end up discussing human near-death experiences

Whether they continue to push the boundary, or someone else does, they can only bring up so many unaccounted-for facts before it’s time for a revolution.

Did the Enlargement of the Human Brain Depend on Two Genes?

The genes, unique to humans, spurred brain growth when introduced in mice and chimpanzee stem cells

While it is quite true that the human brain is very large by animal standards, there is no simple one-on-one relationship between brain size and intelligence.

Can One Person Really Have Two Different Consciousnesses?

The idea that split-brain surgery can create two separate minds is immortal — in science fiction

Real-world research shows the remarkable resilience of damaged brains housing single minds. Our brains are full of complexities and exceptions to rules.

How a Neurosurgeon Showed That Abstract Thought Is Immaterial

Wilder Penfield, one of the first neurosurgeons to split human brains in half to relieve epilepsy, found much more than a treatment

Of his 55,000 brain stimulations that “activated complex networks,” not one generated abstract thought — implying that it is not a “product” of the brain.

What Damaged Brains Tell Us About the Mind

They often provide mute evidence that the human mind is not simply the output of the brain

A recent research paper looks at the way minds work with what’s available, something I often encounter in my practice as a neurosurgeon.

If the Tiniest Brain Is Far From Simple, How Did It Originate?

Eric Cassell’s account of the brain of the nematode worm C. elegans sparks a number of interesting questions

Researchers have used the usually avoided term “directed evolution” — which may suggest design — to account for the worm’s tiny, complex brain.

Even the Tiniest Brain in Nature Is Not Simple

Researchers have found that the worm with smallest known brain shows some surprisingly complex behaviors

The worm C. elegans can learn, using both associative and non-associative learning, despite having a brain of less than 400 neurons.

Researchers Ask: When Are Children Conscious Before Birth?

Human consciousness in general is acknowledged to be a Hard Problem and prenatal consciousness is a subset of that

If examples of terminal and paradoxical lucidity in old age are any guide, we should not conclude that children must lack consciousness before a given stage.

Consciousness: Reductionism’s Final Hill — the One To Die On?

The reductionist has no more information than anyone else about the origin of human consciousness and isn’t making any better sense of the evidence we do have

Is science about following the evidence or about confirming a materialist ideology about science? This is the big neuroscience question of our century.

Looking for Consciousness in All the Wrong Places

Reductionism is nonsense, and “consciousness” is not nestled in clusters of neurons

The higher human ability to think abstractly — to reason and will freely — are not physical abilities and do not come from the brain.
