Brain Power The Speed-Dial Molecule For all that scientists have studied it, the brain remains the most complex and mysterious human organ — and, now, the focus of billions of dollars’ worth of research to penetrate its secrets. This is the first article in a series that will look in depth at some of the insights these projects are producing. Fred R. Conrad/The New York Times Research by Dr. Todd C. Sacktor, above, and André A. Fenton has demonstrated a chemical’s effect on memory with potential implications for treatment of trauma, addiction and other conditions. Readers' Comments If scientists succeed in creating a drug to erase memories, to whom should it be available? Post a Comment »Read All Comments (159) »Researchers in Brooklyn have recently accomplished comparable feats, with a single dose of an experimental drug delivered to areas of the brain critical for holding specific types of memory, like emotional associations, spatial knowledge or motor skills. The drug blocks the activity of a substance that the brain apparently needs to retain much of its learned information. And if enhanced, the substance could help ward off dementias and other memory problems. So far, the research has been done only on animals. But scientists say this memory system is likely to work almost identically in people. The discovery of such an apparently critical memory molecule, and its many potential uses, are part of the buzz surrounding a field that, in just the past few years, has made the seemingly impossible suddenly probable: neuroscience, the study of the brain. “If this molecule is as important as it appears to be, you can see the possible implications,” said Dr. Todd C. Sacktor, a 52-year-old neuroscientist who leads the team at the SUNY Downstate Medical Center, in Brooklyn, which demonstrated its effect on memory. “For trauma. For addiction, which is a learned behavior. Ultimately for improving memory and learning.” Artists and writers have led the exploration of identity, consciousness and memory for centuries. Yet even as scientists sent men to the moon and spacecraft to Saturn and submarines to the ocean floor, the instrument responsible for such feats, the human mind, remained almost entirely dark, a vast and mostly uncharted universe as mysterious as the New World was to explorers of the past. Now neuroscience, a field that barely existed a generation ago, is racing ahead, attracting billions of dollars in new financing and throngs of researchers. The National Institutes of Health last year spent $5.2 billion, nearly 20 percent of its total budget, on brain- related projects, according to the Society for Neuroscience. Endowments like the Wellcome Trust and the Kavli Foundation have poured in hundreds of millions of dollars more, establishing institutes at universities around the world, including Columbia and Yale. The influx of money, talent and technology means that scientists are at last finding real answers about the brain — and raising questions, both scientific and ethical, more quickly than anyone can answer them. Millions of people might be tempted to erase a severely painful memory, for instance — but what if, in the process, they lost other, personally important memories that were somehow related? Would a treatment that “cleared” the learned habits of addiction only tempt people to experiment more widely? And perhaps even more important, when scientists find a drug to strengthen memory, will everyone feel compelled to use it? The stakes, and the wide-open opportunities possible in brain science, will only accelerate the pace of discovery. “In this field we are merely at the foothills of an enormous mountain range,” said Dr. Eric R. Kandel, a neuroscientist at Columbia, “and unlike in other areas of science, it is still possible for an individual or small group to make important contributions, without any great expenditure or some enormous lab.” Dr. Sacktor is one of hundreds of researchers trying to answer a question that has dumbfounded thinkers since the beginning of modern inquiry: How on earth can a clump of tissue possibly capture and store everything — poems, emotional reactions, locations of favorite bars, distant childhood scenes? The idea that experience leaves some trace in the brain goes back at least to Plato’s Theaetetus metaphor of a stamp on wax, and in 1904 the German scholar Richard Semon gave that ghostly trace a name: the engram. What could that engram actually be? I REALLY THOUGHT THTA THEY ARE DEAD; IF THEY ARE NOT - THEY DO NOT AFFECT ME; THERE WAS ATTEMPT TO BRAINWASH PEOPLE WITH INSTALLING "ENGRAMS" - THESE ARE STATIC - THEY ARE NEV ER MOVING AS OUR DREAMS, DAY DREAMS AND PAST IMAGES WHEN AWAKE DO. IN THIS INTEL CENTER THERE IS NO TROUBLE IN RECOGNIZING WHICH IS WHICH. THE PRACTICE OF BRAINWASHING IS INHUMAN AND USELESS. The answer, previous research suggests, is that brain cells activated by an experience keep one another on biological speed-dial, like a group of people joined in common witness of some striking event. Call on one and word quickly goes out to the larger network of cells, each apparently adding some detail, sight, sound, smell. The brain appears to retain a memory by growing thicker, or more efficient, communication lines between these cells. " CALL THIS ONE INTERFACE MEMORY OR INTERACTIONAL MEMORY ( MEANING BETWEEN ANY ELEMENTS OF NATURE); I ALSO CALL IT POWER LINES MEMORY, AND NASA CALLS IT NOT ALWAYS CONSITANTLY BEGINNING OF THE NATURALLY DEVELOPING ARTIFICAIL INTELLIGENCE CENTER I proposed a lot more. Memory is both structured and not - like that image of the American Eagle on the tree from 50 years ago in peoples eyes ( true image that is). Some see it as harbinger - scientifically it is memory of the plaace in process. Do not panic - you did not do the image of the alligator on the Mars ( image only - the lightb event too) |
