Playing the Blame Game
– Video games stand accused of causing obesity, violence, and lousy grades. But new research paints a surprisingly complicated and positive picture, reports Greater Good Magazine’s Jeremy Adam Smith.

Cheryl Olson had seen her teenage son play video games. But like many parents, she didn’t know much about them.

Then in 2004 the U.S. Department of Justice asked Olson and her husband, Lawrence Kutner, to run a federally funded study of how video games affect adolescents.

Olson and Kutner are the co-founders and directors of the Harvard Medical School’s Center for Mental Health and Media. Olson, a public health researcher, had studied the effects of media on behavior but had never examined video games, either in her research or in her personal life.

And so the first thing she did was watch over the shoulder of her son, Michael, as he played his video games. Then, two years into her research—which combined surveys and focus groups of junior high school students—Michael urged her to pick up a joystick. “I definitely felt they should be familiar with the games if they were doing the research,” says Michael, who was 16 at the time and is now 18.

We human beings are social animals. It seems intuitive (even for introverts!) that social contact has benefits. Obviously we need other people to fulfill basic needs such making sure that our genes outlive. Maybe less obviously we seem to need other people to maintain adequate levels of mental well being and motivation.

Even less obviously, social contact may help us improve our brain functions…

Mental fitness seems to depend on a large part on being connected with other people. For instance people with low social support seem to be more prone to mental illness (McGuire & Raleigh, 1986). In 2007, Gladstone and colleagues studied 218 patients with major depression and found out that low social support, especially coming from the family, was associated with chronic depression.

Merely imagining loneliness can negatively affect our behavior…

Over the last months, thanks to the traffic growth of SharpBrains.com (over 100,000 unique visitors per month these days, THANK YOU for visiting today and please come back!), a number of proactive book agents, publishers and authors have contacted us to inform us of their latest brain-related books. We have taken a look at many books, wrote reviews of The Dana Guide to Brain Health book review and Best of the Brain from Scientific American, and interviewed scientists such as Judith Beck, Robert Emmons and James Zull.

Now we are launching a new Author Speaks Series to provide a platform for leading scientists and experts writing high-quality brain-related books to reach a wide audience. We are honored to start the series with an article by Larry McCleary, M.D, former acting Chief of Pediatric Neurosurgery at Denver Children’s Hospital, and author of The Brain Trust Program: A Scientifically Based Three-Part Plan to Improve Memory, Elevate Mood, Enhance Attention, Alleviate Migraine and Menopausal Symptoms, and Boost Mental Energy (Perigee Trade, 2007).

Without further ado, let’s enjoy Dr. McCleary’s article:

Brain Evolution and Why it is Meaningful Today to Improve Our Brain Health

You may feel overwhelmed by the stream of seemingly contradictory suggestions regarding the best way to maintain mental clarity as you age. Based on an analysis of seminal factors in the development of modern brain anatomy, I believe it is possible to make some very compelling recommendations for growing big brains, enhancing their function, and making them resistant to the aging process. These may be loosely categorized as factors pertaining to the mental or physical attributes of the brain. Although they are not truly independent entities, such a conceptualization provides a basis for the generation of brain healthy prescriptions. Diet, physical exercise, and stress reduction enhance neuronal resilience. Sleep and mental stimulation are vital for cognitive ability, learning, and memory.

Diet: Follow a modern shore-based/marine diet including seafood in its most general sense, non-starchy vegetables of all colors, berries, and eggs. Other sources of lean protein containing long-chain omega 3 fatty acids such as free range beef, chicken, bison, or elk are nutritious alternatives.

Physical exercise (Think ‘fight or flight’ activity.): Include all types. Aerobic activities such as swimming, bicycling, walking, or hiking for promotion of vascular health and weight control; resistance training for promotion of neurotrophic factors, naturally occurring compounds that make brain cells more resistant to aging, such as IGF-1 (Insulin-like growth factor-1) and BDNF (Brain-derived neurotrophic factor); and balance, coordination, and agility training such as ping-pong, balance beam, trampoline, and jumping rope to enhance cognitive speed and motor skills.

Stress Control: From an evolutionary perspective, stressors (such as meeting a cave bear) and intense physical activity (running or fighting) were brief in duration and usually occurred together. Modern stressors (psychological or emotional stress) tend to be unremitting and are generally uncoupled from the physical (fight or flight) component, meaning stress develops without any associated physical activity. Such intense physical pursuits are now called exercise. Not surprisingly, exercise is a perfect physiologic antidote for stress due to its beneficial impact on cortisol (the ‘stress’ hormone) and blood pressure and should be incorporated into any program of stress reduction.

Adequate sleep: The body needs rest, but the brain requires sleep. Acute or chronic sleep deprivation causes devastating short and long-term consequences to brain anatomy (synaptic loss) and function (memory and learning difficulties). Off-line information processing and memory consolidation are additional sleep-related benefits.

Mental stimulation: Brain-training, a cognitively challenging lifestyle, novelty, and socialization are vital for the promotion of neuronal plasticity and neurogenesis (the formation of new nerve cells and neuronal connections), the enhancement of specific brain functions such as memory, and the development of cognitive reserve –additional mental processing potential that may be brought online when needed.

The combination of these recommendations, each of which was instrumental in the transformation from primitive to modern nervous systems, provides a template for the most logical approach for enhancing mental function and resisting neurodegeneration as we travel through life.

The Evolutionary Rationale

The human brain clearly has the genetic potential for dramatic expansion. This was illustrated about Read the rest of this entry »

Tom alerts us (thanks!) of a fun book review in the New York Times today, by Abigail Zuger, titled The Brain: Malleable, Capable, Vulnerable, on the book The Brain That Changes Itself (Viking, $24.95) by psychiatrist Norman Doidge. Some quotes:

• “In bookstores, the science aisle generally lies well away from the self-help section, with hard reality on one set of shelves and wishful thinking on the other. But Norman Doidge’s fascinating synopsis of the current revolution in neuroscience straddles this gap: the age-old distinction between the brain and the mind is crumbling fast as the power of positive thinking finally gains scientific credibility.”
• “So it is forgivable that Dr. Doidge, a Canadian psychiatrist and award-winning science writer, recounts the accomplishments of the “neuroplasticians,” as he calls the neuroscientists involved in these new studies, with breathless reverence. Their work is indeed mind-bending, miracle-making, reality-busting stuff, with implications, as Dr. Doidge notes, not only for individual patients with neurologic disease but for all human beings, not to mention human culture, human learning and human history.”
• “Research into the malleability of the normal brain has been no less amazing. Subjects who learn to play a sequence of notes on the piano develop characteristic changes in the brain’s electric activity; when other subjects sit in front of a piano and just think about playing the same notes, the same changes occur. It is the virtual made real, a solid quantification of the power of thought.”
• “The new science of the brain may still be in its infancy, but already, as Dr. Doidge makes quite clear, the scientific minds are leaping ahead.”

Here you have some of our interviews with a few “scientific minds” that have, for years, been “leaping ahead” beyond “positive thinking” into “positive training”:

• Dr. Elkhonon Goldberg on Brain Fitness Programs and Cognitive Training. Dr. Goldberg is a neuropsychologist and clinical professor of neurology at New York University School of Medicine. He was a student and close associate of the great neuropsychologist Alexander Luria, and has written The Executive Brain and The Wisdom Paradox.
• On Cognitive Simulations for Basketball Game-Intelligence: Interview with Prof. Daniel Gopher. Dr. Gopher is Professor of Cognitive Psychology and Human Factors Engineering at Technion, Israel’s Institute of Science, and scientific advisor for IntelliGym.
• Memory training and attention deficits: interview with Professor Bradley Gibson, Associate Professor in the Department of Psychology at University of Notre Dame, and Director of the Perception and Attention Lab there
• On Working Memory Training and RoboMemo: Interview with Dr. Torkel Klingberg, professor at Karolinska Institute, and director of the Developmental Cognitive Neuroscience Lab, part of the Stockholm Brain Institute. He is also the scientific advisor for Cogmed Working Memory Training program (RoboMemo).
• An ape can do this. Can we not? with Dr. James Zull, Professor of Biology and Biochemistry at Case Western University, and author of The Art of Changing the Brain.

Fun article in the San Francisco Examiner today on how High-tech ‘brain gyms’ tone minds, reduce stress. Quotes:

• “SharpBrains and Posit Science are just two of a growing number of start-up companies leading the way in the area of packaging and developing suites of software they call “brain gyms.”
• “SharpBrains offers a suite of products that evaluate buyers’ needs and target their weakness, gently pushing for improvement, Fernandez said. One program helps improve memory using a number game (here); another provides instant biofeedback to users so they can practice breathing and positive thinking to reduce stress (here), Fernandez said.”
• “I can start seeing the changes in my stress level take place right in front of my eyes,” said Baba Shiv (profile here), a neuroscientist and professor at Stanford’s Graduate School of Business, who uses Freeze-Framer 2.0 (here), one of the programs licensed by SharpBrains. By monitoring his stress level through heart monitors hooked to his personal computer at work, he discovered that constantly monitoring his e-mail inbox raised his stress level, Shiv said. Now he limits himself to checking e-mail every two hours, Shiv said.

The reporter did a great job in understanding and communicating a new and sometimes complex topic. Read the article: High-tech ‘brain gyms’ tone minds, reduce stress.
