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…

Why the Brain Can’t Be Understood Simply in Terms of Particles

For the same reasons as a basketball cannot be understood wholly as a “sphere,” the brain is more than particle physics in action

Why the Mind Can’t Just Be the Brain

Thinking it through carefully, the idea doesn't even make sense

Philosopher Roger Scruton (1944–2020) defined neuroscience thus (I paraphrase): Neuroscience is a huge collection of answers with no memory of the questions. Over the past century, neuroscientists have amassed vast libraries of data. But their interpretation of their data on the mind-brain question shows no meaningful understanding of the genuine questions their research is tasked to answer. These questions are ancient: What is the relationship between the soul (or mind) and the body (or brain)? How is it that matter can think? How is it that third-person stuff gives rise to first-person experience? Answers to such questions from the neuroscience community show little evidence of the profound and subtle nature of the questions. Thus, neuroscientists provide answers to questions they…

My Right Hemisphere Is An Atheist! No, Wait …

In reality, split-brain surgery does not split consciousness in any meaningful sense

The atheist neuroscientist who has made bizarre claims about the outcomes of split brain surgery appears not to know much about neurosurgery.

Elon Musk’s Myths About the Mind

According to Musk, everything in the brain is an electrical signal. That’s pretty naive

Neuroscientists used to think that each neuron was as complex as a switch. But newer research shows that each neuron is more similar to a microprocessor. Musk’s 3,000 Neuralink electrodes controlled by a single processor does not remotely match your brain’s 80 billion processors, all linked together.

Philosopher: Consciousness is Not a Problem. Dualism Is!

Physicalist David Papineau says consciousness is just “brain processes that feel like something”

Physicalist David Papineau  argues that consciousness “seems mysterious not because of any hidden essence, but only because we think about it in a special way.” In short, it's all in our heads. But wait, say others, the hard problem of consciousness is not so easily dismissed.

Is There a Creativity Module in the Brain?

Both hemispheres are important for creativity, according to recent research, but the adventure lies beyond

What we are really learning is that minute mapping of the brain is not likely to give us a complete explanation of creativity. Let alone a means of control. Answers, when they appear, lie in the immaterial world of the mind.

How Not To Debate Materialists

This is the story of how a gifted scientist lost a debate with a Darwinist — a debate he should have won

Although ape brains do differ somewhat from human brains in cortical anatomy, it is the similarity between the brains of apes and men, rather than the differences, that provide striking evidence of human exceptionalism.

The Mind Is the Opposite of a Computer

Matthew Cobb, a materialist, only scratches the surface when he explains why your brain is not a computer

Mental activity always has meaning—every thought is about something. Computation, by contrast, always lacks meaning in itself. A word processing program doesn’t care about the opinion that you’re expressing when you use it. In fact, what makes computation so useful is that it doesn’t have its own meaning. Because the mind always has meaning and computation never does, the mind is the opposite of computation.

Can We Understand the Brain the Way We “Understand” New York City?

The “connectome” (a complete “wiring diagram” of the brain) is giving neuroscientists pause for thought

If the brain is immensely complex, it may elude complete understanding in detail. Deep Learning may survey it but that won’t convey understanding to us. We may need to look at more comprehensive ways of knowing.

Why Pioneer Neurosurgeon Wilder Penfield Said the Mind Is More Than the Brain

He gave three lines of reasoning, based on brain surgery on over a thousand patients

Michael Egnor points out that Penfield offered three lines of evidence: His inability to stimulate intellectual thought during brain operations, the inability of seizures to cause intellectual thought, and his inability to stimulate the will. … So he concluded that the intellect and the will are not from the brain. Which is precisely what Aristotle said.

Why the Mind Cannot Just Emerge from the Brain

The mind cannot emerge from the brain if the two have no qualities in common

In his continuing discussion with Robert J. Marks, Michael Egnor argues that emergence of the mind from the brain is not possible because no properties of the mind have any overlap with the properties of brain. Thought and matter are not similar in any way. Matter has extension in space and mass; thoughts have no extension in space and no mass.
