The Next Economy & Sharpening the old Noggin


In order to comprehend and take part in the next economy, most of us will need to take active steps to sharpen and/or preserve our mental acumen. Here is a list of 6 ways from SciAm:
METHOD 1: EXERCISE
Mice that run on wheels increase the number of neurons in their hippocampus and perform better on tests of learning and memory. Studies of humans have revealed that exercise can improve the brain’s executive functions (planning, organizing, multitasking, and more). Exercise is also well known for its mood-boosting effects, and people who exercise are less likely to get dementia as they age....

A variety of mechanisms might be responsible for this brain boost. Exercise increases blood flow to the brain, which also increases the delivery of oxygen, fuel and nutrients to those hard-working neurons. Research has shown that exercise can increase levels of a substance called brain-derived neurotrophic factor (BDNF), which encourages growth, communication and survival of neurons....

METHOD 2: DIET
The brain needs fuel just as the body does. So what will really boost your brainpower, and what will make you lose your mind?...The brain is mostly fat—all those cell membranes and myelin coverings require fatty acids—so it is important to eat certain fats, particularly omega-3 fats, which are found in fish, nuts and seeds. Alzheimer’s disease, depression, schizophrenia and other disorders may be associated with low levels of omega-3 fatty acids.

Fruits and vegetables also appear to be brain superfoods. Produce is high in substances called antioxidants, which counteract atoms that can damage brain cells. Researchers have found that high-antioxidant diets keep learning and memory sharp in aging rats and even reduce the brain damage caused by strokes. That’s food for thought....

METHOD 3: STIMULANTS
Stimulants are substances that rev up the nervous system, increasing heart rate, blood pressure, energy, breathing and more. Caffeine is probably the most famous of the group. (It is actually the most widely used “drug” in the world.) By activating the central nervous system, caffeine boosts arousal and alertness.....One study showed that the equivalent of two cups of coffee can boost short-term memory and reaction time. Functional MRI scans taken during the study also revealed that volunteers who had been given caffeine had increased activity in the brain regions involving attention. In addition, research suggests caffeine can protect against age-related memory decline in older women.

METHOD 4: VIDEO GAMES
.....Surgeons who spend at least a few hours a week playing video games make one-third fewer errors in the operating room than nongaming doctors do. Indeed, research has shown that video games can improve mental dexterity, while boosting hand-eye coordination, depth perception and pattern recognition. Gamers also have better attention spans and information-processing skills than the average Joe has. When nongamers agree to spend a week playing video games (in the name of science, of course), their ­visual-perception skills improve.....

Video games activate the brain’s reward circuits but do so much more in men than in women, according to a new study. Researchers hooked men and women up to functional MRI machines while the participants played a video game designed for the study. Both groups performed well, but the men showed more activity in the limbic system, which is associated with reward processing. What is more, the men showed greater connectivity between the structures that make up the reward circuit, and the better this connection was in a particular player, the better he performed. There was no such correlation in women. Men are more than twice as likely as women are to say they feel addicted to video games.

METHOD 5: MUSIC
Music can...activate your brain’s reward centers and depress activity in the amygdala, reducing fear and other negative emotions.

....music does seem to possess some good vibrations. It can treat anxiety and insomnia, lower blood pressure, soothe patients with dementia, and help premature babies to gain weight and leave the hospital sooner.

Music training can bolster the brain. The motor cortex, cerebellum and corpus callosum (which connects the brain’s two sides) are all bigger in musicians than in nonmusicians. And string players have more of their sensory cortices devoted to their fingers than do those who don’t play the instruments..... some studies have indeed shown that music lessons can improve the spatial abilities of young kids.

METHOD 6: MEDITATION
Meditation, or the turning of the mind inward for contemplation and relaxation, seems to help all types of conditions—anxiety disorders, sure, but it can also reduce pain and treat high blood pressure, asthma, insomnia, diabetes, depression and even skin conditions.

...Researchers are now illuminating the actual brain changes caused by meditation by sticking meditators into brain-imaging machines. For one, although the brain’s cells typically fire at all different times, during meditation they fire in synchrony. Expert meditators also show spikes of brain activity in the left prefrontal cortex, an area of the brain that has generally been associated with positive emotions. And those who had the most activity in this area during meditation also had big boosts in immune system functioning.

Meditation can increase the thickness of the cerebral cortex, particularly in regions associated with attention and sensation. (The growth does not seem to result from the cortex growing new neurons, though—it appears that the neurons already there make more connections, the number of support cells increases, and blood vessels in that area get bigger.) _Sciam
There you have it. A glimpse into the future, and a few of the things you will need to do to be able to take advantage of it.

Thanks Zenpundit.

Good information. I think that brain fitness will eventually be as much a part of people's daily lives as physical fitness.

Readers might be interested in Susanne Jaeggi and Martin Buschkuehl's study on Improving Fluid Intelligence by Training Working Memory (PNAS April 2008) which recorded increases in mental agility (fluid intelligence) of more than 40% after 19 days of focused working memory training.

I was so impressed that I contacted the research team and developed a software program using the same method so that anyone can achieve these improvements at home.

Hi Al,

Great post, as usual.

I keep bumping into this idea while lurking around the economic world, the article isn't up to Wikipedia standards yet, but is a fairly good summary:

http://en.wikipedia.org/wiki/The_Natural_Economic_Order

A more current take on "Natural Money:"

http://en.wikipedia.org/wiki/The_Future_of_Money:_Beyond_Greed_and_Scarcity


There is a strong chance that any nation that can adopt currency with these properties would rapidly take the economic lead over its rivals.
