One Side of Christine Honeycutt's Face Did Not Grow

Bookmark and Share One of Christine’s teachers told her to wipe the ink off her forehead. “I can’t,” she replied. “It’s always there.”

There were other troubling signs: One side of Christine’s forehead was normal, but the other was “meaty,” Vicki recalls. And her ears looked out of proportion to one another—an asymmetry that seemed to extend over her entire face. . . .

Hero is Okay but Wimp is Better: Future Prediction and The Illusion of Courage

Bookmark and Share
Throwing yourself on a grenade to shield your buddies. Slugging an assailant with a purse to protect your child. Wing-walking atop a biplane at 10,000 feet. Jumping a motorcycle over three parked cars. Some people would say they could do one or all of these actions.

All of that is rather extreme. Most of us say we would not do it. On the other hand, many people predict they would engage in actions relatively mild compared to extreme behavior. These are situations like investing in an agressive stock, or giving a speech in front of two hundred people, or standing up to an intimidating boss. Would you do it?

For people who say yes, recent research indicates that many are wrong.

Alzheimer's Is Not Inevitable for the Aging Brain

Bookmark and Share "A 115-year-old woman who remained mentally alert throughout her life had an essentially normal brain, with little or no evidence of Alzheimer's disease, according to a study in the August issue of Neurobiology of Aging. The findings question the assumption that Alzheimer's disease or other forms of dementia will inevitably develop, if people live long enough.

Amazingly TIny Brain But A Normal Life

Bookmark and Share "A French civil servant has been found to have a huge cavity filled with fluid in his head -- yet lives a completely normal life.

The commonly spouted wisdom that people only use 10 percent of their brain power may have been dismissed as a myth, but one Frenchman seems to be managing fine with just a small fraction of his actual brain.

In fact the man, who works as a civil servant in southern France, has succeeded in living an entirely normal life despite a huge fluid-filled cavity taking up most of the space where his brain should be.

The High Priests of Physics and The Occult Language of Mathematics

Bookmark and Share

There is nothing in the laws of the cosmos that says physicists are supposed to be happy. Steven Weinberg said something like that, voicing an opinion similar to Feynman's, who in effect said of quantum mechanics that you may not like it but that's the way it is.

A group of thinkers refuse to accept it as the way it is.  Concerned for their reputation, they do not like "sloppy thinkers who might well be called 'cranks,' who if given wide publicity would harm" their cause.

I will leave you to form your own opinions.

They are "devoted mainly to broad-ranging, fully open-minded criticism, at the most fundamental levels , of the often irrational and unrealistic doctrines of modern physics and cosmology; and to the ultimate replacement of these doctrines by much sounder ideas developed with full respect for evidence, logic, and objectivity. Such reforms have long been urgently needed; and yet there is no area of scholarship more stubbornly censorial, and more reluctant to reform itself."

Stephen Hawking: Philosophy Is A Waste of Time

Bookmark and Share

I will be away until January
--------------------
Stephen Hawking believes philosophy as practised nowadays is a waste of time and philosophers a waste of space. "More precisely, he wrote that philosophy is ‘dead’ since it hasn’t kept up with the latest developments in science, especially theoretical physics.

The Puzzle of Face Space: Your Eyes May See When Your Brain Does Not

Bookmark and Share

In Oliver Sacks' classic The Man Who Mistook His Wife For A Hat the title is comic and almost absurd but his book provides fascinating explanation of a neurological condition in which a man does mistake his wife for a hat without realizing it. Sacks introduces the lay reader to another phenomenon--how a stroke leaves a person unable to see things on one side of the visual field and how the stroke victim also has no inkling that anything is wrong or missing with his perception. In fact, in both cases, nothing is wrong with the eyes, only with the way the brain processes visual information.

There is a name for this condition, prosopagnosia, and it describes a small fraction of people who cannot recognize faces--even the faces of loved ones  The condition puzzles researchers but they are beginning to understand how facial recognition works, which may help those with prosopagnosia.  With her colleagues, Marlene Behrmann at Carnegie Mellon University has gathered some pieces of the puzzle by comparing the brains of individuals who are face-blind to those who are face-sighted. Their results hint at how we recognize faces not in a flash of insight, not as a kind of photographic image, but by building up recognition on a neurological assembly line. Recognition is encoded in the brain as face space.

Consciousness and the Soul Solved

Even atheists have souls, Nicholas Humphrey might jest in a book both difficult and fluidly written. In Soul Dust: The Magic of Consciousness he believes the soul can be explained along with the hard problem of consciousness.

A Little-Known Story: Maria Leontievna Bochkareva, Who Met President Wilson

Bookmark and Share
Of peasant stock, beaten by her alcoholic father, working since age eight, she married at fifteen and left her husband when he began beating her and swore to kill her. She married again, followed her husband to exile in Siberia but left him when he tried to hang her. In 1914 she fought for the Czar as the only woman in the 25th Tomsk Reserve Battalion, where fellow soldiers taught her to read and write. She was wounded twice, decorated three times for bravery, fought with frost-bitten feet, bayoneted German soldiers, and pulled fallen comrades to safety.

Who's In Charge?: Did Your Neurons Really Make You Do It?

Bookmark and Share

Free will or no free will? Benjamin Libet, John Dylan Haaynes, and so many others have weighed in on the issue. Now we have a new point of view based on new evidence. "Many neuroscientists have maintained a long-standing opinion that what we experience as free will is no more than mechanistic patterns of neurons firing in the brain. Although we feel like free agents contemplating and choosing, they would argue that these sensations are merely an emotional remnant that brain activity leaves in its wake. If these neuroscientists are right, then free will isn’t worth much discussion.

Michael S. Gazzaniga, professor and director of the SAGE Center for the Study of the Mind at the University of California at Santa Barbara, seriously disagrees.

Neuroscience provides more and more evidence for a mechanistic view of the human mind. A lot of people find that bleak and they don’t like it.Once you learn how the machine works, does that mean that you’re not responsible for your actions because your behavior may be determined? No, I don’t think it means that at all, says Gazzaniga.MoreBookmark and ShareSubscribe in a reader

How Will Brain Science Change The Legal System?

Bookmark and Share  If you were to lose the tip of your little finger in an accident, you’d be saddened, but your conscious experience would be no different. By contrast, if you were to damage an equivalently sized piece of brain tissue, this can change your capacity to understand music, name animals, see colors, judge risk, make decisions, send signals to your muscles, use verbs or perform any of the other hidden, daily feats that we pull off seemingly without effort.


Thousands of natural experiments with brain tumors, degenerative disorders, genetic mutations, drug addictions and traumatic brain injury have taught a simple lesson: our hopes, ideas, desires and behaviors depend directly on the state of the enigmatic lump of thinking stuff.

Thomas Metzinger: What Is Behind Our Talk About The Self

Bookmark and Share
Here is an excerpt of an interview between Ginger Campbell, MD, and Thomas Metzinger, PhD, author of The Ego Tunnel: The Science of the Mind and the Myth of the Self

Dr. Campbell: I guess I was really wanting to start with the working definition that you gave in your book. Why in the book did you pick the phrase “consciousness is the appearance of a world” as your working definition? I’m going to assume it’s a working definition, since that’s the way you defined it in the book.

Dr. Metzinger: For a popular accessible book I needed a simple working definition—and “the appearance of a world” is just that. It happens when you wake up in the morning: a world appears to you.
