Improve Your Brain's Capacity for Learning!

On the lighter, yet still important, side of learing and also something this old lady struggles with from time to time (focus, concentration, alertness), I thougt I would share with the group my wandering and seeking discoveries.  Pay special attention to item No. 2
A few excerpts  from the WebMD Slideshow:

1.  Fish Really is Brain Food
A protein source associated with a great brain boost is fish -- rich in omega 3 fatty acids, essential for brain function and development. These healthy fats have amazing brain power: higher dietary omega 3 fatty acids are linked to lower dementia and stroke risks; slower mental decline; and may play a vital role in enhancing memory, especially as we get older.  For brain and heart health, eat two servings of fish weekly.
2.  Add a Daily Dose of Nuts and Chocolate
Nuts and seeds are good sources of the antioxidant vitamin E, which is associated with less cognitive decline as you age. Dark chocolate also has powerful antioxidant properties, and contains natural stimulants like caffeine, which can enhance focus and concentration. Enjoy up to an ounce a day of nuts and dark chocolate to provide all the benefits you need without excess calories, fat, or sugar.
3.  Add Avocados and Whole Grains
Every organ in the body depends on blood flow, especially the heart and brain. Eating whole grains and fruits like avocados can reduce the risk of cardiovascular disease and enhance blood flow, offering a simple, tasty way to fire up brain cells. Whole grains, like popcorn and whole wheat, also contribute dietary fiber and vitamin E, while avocados have fat -- but a good-for-you, monounsaturated fat that contributes to healthy blood flow.
4.  Blueberries Are Super Nutritious
Research in animals shows that blueberries help protect the brain from oxidative stress and may reduce the effects of age-related conditions such as Alzheimer's disease or dementia. Studies also show that diets rich in blueberries significantly improved both the learning capacity and motor skills of aging rats, making them mentally equivalent to much younger rats.

All Things Considered, May 12, 2009 · Nowadays, some scientists say, you can exercise your brain the way you exercise your body.
If you sleep more, eat less and get plenty of exercise — using your body and your brain — says Richard Restak, you can improve your intelligence over the years and help stave off the dementia that comes with old age.
Restak, a psychiatrist in Washington, D.C., is the author of the just-published Think Smart: A Neuroscientist's Prescription for Improving Your Brain's Performance. Research shows, he says, that the brain responds to stretching and challenging exercises in every stage of life.
An older person "can still take up a language, you can learn to play bridge," he says, "and that establishes connections between neurons, and the synaptic density begins to increase."
In other words, as we get older, we can still get smarter.
The key, Restak says, is to exercise the three different types of memory: long-term memory, sensory memory and working memory.
Making Memories — Stronger
"Long-term memory is just everything we know about history, things about our life, important dates, important things that happened, all the things that separate one person from another," Restak explains. "You could call it the treasure-trove of information that you have. So that's long-term memory, and we're forming it all the time."
He suggests an exercise to increase the strength of long-term memory: Choose a year in your past and associate it with what you were doing — where you were in school or where you were working. Then expand your recollections into other events in the world at large — sporting contests, political activities, major catastrophes and cultural happenings.
"It's called a reminiscent exercise," he says. "It can be used at any time in life."
There is controversy surrounding the ability to improve memory and intelligence through exercises. Torkel Klingberg, a Swedish brain researcher and author of The Overflowing Brain, says that "certain cognitive functions, such as attention, working memory and possibly reasoning … can be affected by training." But he is less certain that exercises will strengthen long-term memory.
Restak says that we are constantly adding to our long-term memory, and learning to associate images or emotions with those memories will increase the chances of retrieval.
Your Brain On Peanut Butter
Sensory memory is the recall associated with the senses, such as touch, smell and hearing. Restak says, "Sensory memory is something you don't hear too much about, yet it's the most important part of laying down a memory: Paying attention to what's going on."
For instance, we don't remember a person's name, he says, "because we weren't listening when we met them. Why don't we remember certain facts? It's because we weren't really there."
To stimulate the sensory memory, Restak suggests testing your powers of olfaction. He writes that "eighty-five percent of the U.S. population can identify the following seven odors: baby powder, chocolate, cinnamon, coffee, mothballs, peanut butter and soap."
So go into the kitchen, close your eyes and ask someone to hand you each of those items — opened so you can sniff them — one by one. Or use spices. Or other familiar odors to connect your nose to your memory. Try to identify as many as you can. Then try again and see if you can improve your fragrance memory.
The Working Memory Workout
Of all forms of memory, the working memory is the most vital to our everyday lives. "That's the area of being able to keep in mind several things at once," Restak says.
To exercise working memory, Restak suggests a few radical ideas, including video games for adults that reinforce focus and dexterity skills.
And a self-quiz: Name the U.S. presidents, going backward from Barack Obama to John F. Kennedy. Then, arrange them in chronological order starting with Kennedy, assigning each his proper party affiliation (so, Kennedy — Democrat; Johnson — Democrat; etc.). Next, list them alphabetically. That ability to perform more than one function at a time, Restak says, stretches the working memory.
In the end, Restak believes we should think of the brain's growth over the years as a series of marathons. He credits Canadian neurologist Kenneth Rockwood with the metaphor. In Think Smart, Rockwood says, "As our brains age, we must prepare them to resist injury — equip them with good education, train them thoughtfully with challenging regimens, support them with nurturing environments and be prepared to refresh them from time to time."
Looking at the old noodle that way, Restak says, encourages an active brain — one that will keep working and stay fit through the years.
