In the recent podcast, “Michael Egnor on Whether People in Comas Can Think,” Robert J. Marks raised an interesting point with Egnor: Can people in comas think abstractly or do they form thoughts only at a much more basic level, given how physically distressed they are? The answer might surprise you.

Pioneering research using brain imaging (fMRI) over the last fifteen years has shown that, even in deep coma, people can hear, understand, and respond. It’s no longer just anecdotes from caregivers. The controversial Terri Schiavo case might be decided very differently today.

As we struggle with the COVID-19 crisis, many are beginning to ask hard questions about how our system works, its strengths, weaknesses, and vulnerabilities. One vulnerability might be too heavy reliance on a single source for data modeling and predictions. Considering all the uses to which AI may be put in health care, getting our guidance exclusively from the Institute for Health and Metric Evaluation for modeling is reckless.

Of 83 studies of the performance of the Deep Learning algorithm on diagnostic images, only two had been randomized, as is recommended, to prevent bias in interpretation.

The true significance of the split-brain experiments goes far beyond the significance of the lateralization of the brain; your essential unity also points to the immaterial nature of the mind.

His specialty was reconstruction of the skulls of children born with horrendous skull deformities, and he pioneered the surgery of separation of craniopagus (Siamese) twins.

When a field is hot, there is a race to publish. With a large number of researchers trying a wide variety of treatments, it’s almost certain that that someone will find a coincidental pattern that is statistically significant but meaningless. The only solution, alas, is further testing.

The authors of the paper saying that the virus could not have been designed base their findings on the fact that current software would not have predicted this result. I am not claiming that the virus was designed, only that a researcher need not have relied on this software to design a virus. The paper makes a faulty assumption.

Big social media companies have long wanted to replace human content moderators with AI. COVID-19 quarantines have only intensified that discussion. But AI is far, far from ready to successfully moderate content in an age of where virtual monopolies make single point failure a frequent risk.

Chinese scientists worked together swiftly and seamlessly to sequence the virus, (completed February 25), even as the government was downplaying the extent of the problem and silencing doctors who attempted to warn colleagues and the public. The Wuhan public erupted in anger when the government demanded a show of gratitude for its efforts rather than theirs.

If we are going to hold some people up as business icons, why should it be those who—in the present COVID-19 troubles—have relations with China that necessarily raise questions?

We are more scientifically certain of God’s existence than we are of quantum mechanics or Newtonian or relativistic gravitation. The logic is rigorous.

A key problem for amputees is that the nerves in the remaining part of a limb used to control a prosthesis usually produce only tiny signals. They are often hard for the nervous system to distinguish from mere noise. So, to control the limb by thoughts, the signals must be amplified. A new technique uses muscle grafts to amplify the signals.

If God is real, then prayer is probably the first thing you want to do in a crisis. A plea to the Boss is a fine preamble to the grunt work of managing a crisis. I’m a neurosurgeon, and I pray before each operation. It really helps.

But that is not the same thing as saying that it reliably improves outcomes or even enjoyment of life. If a powerful AI method reliably detected the very early onset of Alzheimer, it might ruin a senior's early retirement years without changing the outcome much. Getting the most from AI will include determining the relationship between what it can potentially do and what will provide a medical benefit.

While China’s citizens are living in an information vacuum, the government has stepped up its surveillance strategies in order to track people who have been near someone infected with the coronavirus. Some commentators consider these measures disproportionate to the actual risk posed to others and in violation of human rights. Others see them as necessary.

Coronavirus provides a test. The Chinese Communist Party offers mainland Chinese people security and prosperity in exchange for the sacrifice of personal freedom. But when the government cannot uphold its end of the agreement—security—the people may become less tolerant of the human rights violations. And the age of information makes it much easier to discover them.

Media often co-operate with researchers’ inflated claims about machine learning’s powers of discovery. An ingenious “creative” approach to accuracy enables the misrepresentation, says data analyst Eric Siegel.

Why does fasting clarify the mind, instead of making us dizzy and anxious for food? Jay Richards, author of Eat, Fast, Feast (2020), says researchers now think that ketosis (burning stored fat for energy instead of blood sugar) naturally produces clearer thinking.
