How Brain Imaging Could Help Predict Alzheimer's

How Brain Imaging Could Help Predict Alzheimer's
Developing drugs that effectively slow the course of Alzheimer’s disease has been notoriously difficult. Scientists and drug developers believe that a large part of the problem is that they are testing these drugs too late in the progression of the disease, when significant damage to the brain makes intervention much more difficult. “Drugs like Lilly’s gamma secretase inhibitor failed because they were tested in the wrong group of patients,” says Sangram Sisodia, director of the Center for Molecular Neurobiology at the University of Chicago. People in the mid or late stages of the disease “are too far gone, there is nothing you can do.” New brain imaging research may help solve that problem. Two studies presented at the Society for Neuroscience conference in San Diego this week identified changes in the brains of people who would go on to develop the disease.

Navy: Grow Sailors’ Brains With iPhone App It’s not that the Navy is calling you stupid. The seafaring service just wants to actually see your brain grow. High on the Navy’s just-released wish list for designs from small businesses is a “brain-fitness training program” that sailors can use to sharpen their cognitive skills. Ways to Improve Human Intelligence This briefing is intended to pull into one convenient, single frame of reference a body of key information which currently is scattered across a great many different contexts. Until recently, even the possibility of any such information existing was, for essentially political reasons and funding reasons, denied by most of our institutions, together with most of our educators and psychologists, so that such findings as were made in various contexts and circumstances never got discussed across a broader context. Now that it is evident that the brain, and one's intelligence, are highly changeable and that a wide variety of conditions, arrangements and techniques may be employed to improve both brain functioning and intelligence to even a profound degree, we need to make a start on getting a lot of this key information organized to where you and other inquirers can more readily get at it, understand it, and use it.

Neurotheology: This Is Your Brain On Religion Principles of NeurotheologyBy Andrew B. NewbergPaperback, 284 pagesAshgateList price: $29.95 "Neurotheology" is a unique field of scholarship and investigation that seeks to understand the relationship specifically between the brain and theology, and more broadly between the mind and religion. Neuroscience of free will Neuroscience of free will is the part of neurophilosophy that studies the interconnections between free will and neuroscience. As it has become possible to study the living brain, researchers have begun to watch decision making processes at work. Findings could carry implications for our sense of agency and for moral responsibility and the role of consciousness in general.[1][2][3] Relevant findings include the pioneering study by Benjamin Libet and its subsequent redesigns; these studies were able to detect activity related to a decision to move, and the activity appears to begin briefly before people become conscious of it.[4] Other studies try to predict activity before overt action occurs.[5] Taken together, these various findings show that at least some actions - like moving a finger - are initiated unconsciously at first, and enter consciousness afterward.[6]

Brain Areas Critical To Human Time Sense Identified Timing is everything. It comes into play when making split second decisions, such as knowing when to stop at a red light, catch a ball or modulate rhythm when playing the piano. Now researchers at the Medical College of Wisconsin in Milwaukee and Veterans Affairs Medical Center in Albuquerque have identified areas in the brain responsible for perceiving the passage of time in order to carry out critical everyday functions. Their study is the first to demonstrate that the basal ganglia located deep within the base of the brain, and the parietal lobe located on the surface of the right side of the brain, are critical areas for this time-keeping system. Their results are published in the current issue of Nature Neuroscience.

Religion May Cause Brain Atrophy Faith can open your mind but it can also cause your brain to shrink at a different rate, research suggests. Researchers at Duke University Medical Centre in the US claim to have discovered a correlation between religious practices and changes in the brains of older adults. The study, published in the open-access science journal, Public Library of Science ONE, asked 268 people aged 58 to 84 about their religious group, spiritual practices and life-changing religious experiences. Changes in the volume of their hippocampus, the region of the brain associated with learning and memory, were tracked using MRI scans, over two to eight years. Scientists extract images directly from brain Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11. According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes.

Winsights, Part 71, "Eye Tracks" (December 2003) When last I checked, around the start of the new millennium, developmental optometry and practitioners were listed under "Behavioral Optometrists" — ditto with opthalmologists — but since then we now see ten pages of listings under "Developmental." The term "developmental" is much more descriptive of the profession. This should make it easier for you to track down and use one more major sets of ways to enhance your abilities, as described in this briefing. How Great Entrepreneurs Think What distinguishes great entrepreneurs? Discussions of entrepreneurial psychology typically focus on creativity, tolerance for risk, and the desire for achievement—enviable traits that, unfortunately, are not very teachable. So Saras Sarasvathy, a professor at the University of Virginia's Darden School of Business, set out to determine how expert entrepreneurs think, with the goal of transferring that knowledge to aspiring founders. While still a graduate student at Carnegie Mellon, Sarasvathy—with the guidance of her thesis supervisor, the Nobel laureate Herbert Simon—embarked on an audacious project: to eavesdrop on the thinking of the country's most successful entrepreneurs as they grappled with business problems.

Controlling Computers with Your Mind November 8, 2010 Scientists used a brain-computer interface to show how the activity of just a few brain cells can control the display of pictures on a computer screen. The finding sheds light on how single brain cells contribute to attention and conscious thought. Patients were asked to focus on 1 of 2 superimposed images, here of Michael Jackson and Marilyn Monroe. Researchers have been making great progress in developing brain-computer interfaces—devices that let a person's thoughts guide the actions of a computer. This technology can potentially help paralysis patients control prosthetic limbs and communicate.

Winsights, No. 28 (page 1 of 2), "Breathing as a way of life Many years ago, when I was still studying to become an educator, I used to marvel how despite the fact that most people had children, and despite the billions of parent-child relationships already experienced thus far by the civilized human race, no one until Jean Piaget, researching in Switzerland, ever really looked at his own children. (Piaget, subsequently all the rage in American educational circles, was not even a psychologist; he was a biologist, trained to observe, and his first papers were records of his observations on the behavior of oysters!) All those billions of parent-child relationships, I used to marvel, yet only one looked closely at what's right there in front of everyone! What else, I mused, could we be overlooking today that's equally common to experience? What a shock to realize that, in retrospect, every experience and every kind of experience has its own breathing pattern attached to it. In retrospect, the reader will also find this true for himself or herself.
