Sports' Brain Injuries

Ouch. New studies about football and head injuries are positively frightening. According to a study of three Division I college teams sponsored by the National Institutes of Health (published in the Journal of Athletic Training), college players sustain more total hits to the head in practices than in games. More research: Nationwide Children’s Hospital in Columbus, Ohio, found that a college football player participates in about 12 practices for every game played during the full year. No other N.C.A.A.-sponsored sport had a ratio higher than 4 to 1. The risk of all the head trauma? Chronic traumatic encephalopathy. You or a loved one DO want to avoid this!! Check out the article.

Neurons - Differ like Snowflakes

First we hear that your brain is as unique as your fingerprints. Now we hear that much like snowflakes, no two neurons are exactly alike. "But it's not the size or shape that sets one neuron apart from another, it's the way it responds to incoming stimuli." According to researchers at Carnegie Mellon University, this diversity is critical to overall brain function and essential in how neurons process complex stimuli and code information. Estimates say that the human brain alone has upwards of 100 billion neurons, and that the brain itself is considered to be one of the most sophisticated computers that exists. Now researchers say every neurons (chip?) is unique? Check out the report for yourself.

Michelangelo - Anatomist and Painter

R. Douglas Fields, PhD, is Chief of the Nervous System Development and Plasticity Section at the National Institute of Child Health and Human Development. He is also Editor-in-Chief of the journal Neuron Glia Biology and author of "The Other Brain," about glial cells in the brain that do not communicate using electricity but that support neurons. In the Scientific American (May 27, 2010) an article by Fields is entitled, "Michelangelo's secret message in the Sistine Chapel: A juxtaposition of God and the human brain." You may enjoy reading about Michelangelo and "his hidden anatomical illustrations" that have been found—painted on the ceiling of the Sistine Chapel (notably, sketches of brain anatomy.)

Plasticity of Human Brain

Research University of California, San Francisco (UCSF) of commercial brain fitness program from Posit Science Corporation: practising simple visual tasks can improve the accuracy of short-term, or “working” visual memory. Folowing 10 hours of training, participants improved their perceptual abilities significantly (e.g., increased the accuracy of visual working memory by about 10 %) bringing them up to the level of younger adults. psychiatry at UCSF. Findings help to confirm that perceptual improvements with simple discrimination training can transfer to improved working memory in older adults, and that this increase in memory accuracy is linked to changes at the neural level. That is very good news!

Your Brain and Neuromarketing

Neuromarketing is a new field of marketing that uses neuroscience, psychology, and other cognitive science techniques to study consumer responses to marketing stimuli. Some of the responses measured include eye tracking, heart rate, electroencephalography (e.g., EEG, functional magnetic resonance imaging – fMRI, galvonic skin responses). Will you purchase more Campbell's Soup because of this? The company hopes so! An artible by Ilian Brat entitled "The Emotional Quotient of Soup Shopping" outlines some of the neuromarketing techniques that the Campbell Soup Company has employed to warm up customer responses to shelf displays. And here I thought my "thoughts" of Campbell's soup were pretty much based on childhood memories! (smile)

Sleep for "Surge"

Journal of Neuroscience report of rat studies: In the initial stages of sleep, energy levels increase dramatically in brain regions found to be active during waking hours. Adenosine triphosphate (ATP), the energy currency of cells, was found to surge during non-REM sleep. This surge of cellular energy may replenish brain processes needed to function normally while awake. Sleep appears to be necessary for this energy surge to occur. So, are you making sure your brain receives enough sleep?

Snowball, Music, and the Brain

Several years ago, Aniruddh D. Patel, a 44-year-old senior fellow at the Neurosciences Institute in San Diego, wrote “Music, Language, and the Brain.” Oliver Sacks described this book as “a major synthesis that will be indispensable to neuroscientists.” Recently, Patel was in New York City and was interviewed. A condensed and edited version of that interview was published in the NY Times: "A Conversation With Aniruddh D. Patel - Exploring Music’s Hold on the Mind." Patel talked about "Snowball," for example, the sulfur-crested Cockatoo that can keep time to music (previously believed to be an ability found only in humans). Patel also commented about a neurologist in Boston who has stroke victims learn simple phrases by singing them (which has proved more effective than having them repeat spoken phrases, the traditional therapy). When the language part of the brain has been damaged, you can sometimes recruit the part that processes music to take over. Fascinating!
