Use It or Lose It: The Principles of Brain Plasticity - 3 views

  • You probably haven't realizd it, but as you acquire an ability – for example, the ability to read – you have actually created a system in the brain that does not exist, that's not in place, in the non-reader. It [the ability; the brain system that controls the ability] actually evolves in you as it has been acquired through experience or learning.
  • "There are some very useful exercises at www.BrainHQ.com that are free, and using them can give a person a better understanding of how exercising your brain can drive it in a rejuvenating direction. Using exercises at BrainHQ, most people, of any age, can drive sharp improvements in brain speed and accuracy, and thereby rewire the brain so that it again represents information in detail," he says.
  • Children operating in the 10th to 20th percentile of academic performance are commonly able to improve their scores to the middle or average level with 20-30 hours of intensive computer-based training. "That's a big difference for the child," he says. "It carries most children who are near the bottom of the class, on the average, to be somewhere in the middle or above average in the class. And that gives struggling children a chance to really succeed and in many cases excel in school."

  • Careful controlled studies in seniors have also been reported in scientific journals. After 40 hours of computer-based training, the average improvement in cognitive performance across the board was 14 years. On average, if you were 70 years old when you underwent the training after 40 hours of brain training, your cognitive abilities operated like that of a 56-year old. Equally strong or even greater effects were seen in 40 to 50 year olds using the program. Individuals who worked on the BrainHQ exercises at home did just as well as those who completed training in a clinic or research center.
  • Ideally, it would be wise to invest at least 20 minutes a day. But no more than five to seven minutes is to be spent on a specific task. When you spend longer amounts of time on a task, the benefits weaken. According to Dr. Merzenich, the primary benefits occur in the first five or six minutes of the task.
  • Find ways to engage yourself in new learning
  • "When it matters to you, you are going to drive changes in your brain," he explains. "That's something always to keep in mind. If what you're doing seems senseless, meaningless, if it does not matter to you, then you're gaining less from it."
  • Get 15-30 minutes of physical exercise each day,
  • Spend about five minutes every day working on the refinement of a specific, small domain of your physical body.
  • You can typically improve yourself to the highest practical or possible level in anywhere between five to a dozen brief sessions of seven or eight minutes each. Again, having a sense of purpose is crucial.
  • Stay socially engaged.
  • Practice "mindfulness,"
  • Foods have an immense impact on your brain, and eating whole foods as described in my nutrition plan will best support your mental and physical health.
  • The medical literature is also showing that coconut oil can be of particular benefit for brain health, and anecdotal evidence suggests it could be very beneficial in the treatment of Alzheimer's disease.
  • Optimize your vitamin D levels
  • Take a high-quality animal-based omega-3 fat.
  • Avoid processed foods and sugars, especially fructose
  • Avoid grains
  • Avoid artificial sweeteners
  • Avoid soy
  • Men who ate tofu at least twice weekly had more cognitive impairment, compared with those who rarely or never ate the soybean curd, and their cognitive test results were about equivalent to what they would have been if they were five years older than their current age.
  •  
    "It was once thought that any brain function lost was irretrievable. Today, research into what's referred to as "brain plasticity" has proven that this is not the case. On the contrary, your brain continues to make new neurons throughout life in response to mental activity."

Cognitive Daily: A quick eye-exercise can improve your performance on memory tests (but only if you're right-handed) - 0 views

  • If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.
  • It may be that this quick activity helps facilitate interaction between the brain hemispheres.
  • any activity that encourages communication between the hemispheres is likely to increase recall.
  • ...6 more annotations...
  • people who have poorer interactions between the hemispheres should benefit more than others. Who has less interactions between hemispheres? People who are strongly right-handed.
  • Strongly right-handed students remembered significantly more words if they moved their eyes compared to keeping their eyes still. Non-strongly-right-handed students (including left-handers) remembered the same number of words regardless of whether they moved their eyes before the test.
  • strongly right-handed students had significantly fewer false alarms after they moved their eyes back and forth. But for non-strongly-right-handed people, the reverse occurred; moving their eyes caused them to falsely remember more words. So overall, while the eye-saccade exercise helped right-handers, for lefties and for those who didn't have a strongly dominant hand, the exercise actually harmed their performance.
  • You might think that only side-to-side movement would improve performance, but Lyle's team found that moving your eyes up and down caused the same effect.
  • researchers say that other studies have shown that any eye movements increase bilateral activity in the frontal eye field, so it's still possible that hemispheric connectivity can explain the improved performance after eye movements.
  • So why doesn't the exercise work the same way for left-handers? Left handers (and ambidextrous individuals) already have a high level of hemispheric connectivity. Lyle's team speculates that there might be such a thing as too much connectivity, which results in a decrease in performance.

    Several studies have confirmed this bizarre proposition: If you're taking a test of rote memorization, like words from a list, move your eyes from side to side for about 30 seconds before you start.

Visual training to retain driving competence - and your independence! | On the Brain by Dr. Mike Merzenich,Ph.D. - 1 views

  • Today, Posit Science announced the release of a new computer-based visual training tool, DriveSharp, specifically designed to improve the performance abilities of adult automobile drivers to a degree that can be expected to very substantially impact their driving safety.
  • Again, with a few hours of intensive training, a youthful MOT performance level can be achieved for most individuals. The result: A still FURTHER increase of driving safety.
  • In our fast-moving world, losing control of one’s peripheral vision is a main cause of driving accidents.
  • ...11 more annotations...
  • Ball and Roenker demonstrated that these losses are substantially reversible, through appropriate, intensive training, in almost all older drivers. UFOVs can be re-expanded to relatively youthful ability levels through only a few hours of exercise. The result: About 50% fewer driving accidents in the over-65 population.
  • Moreover, once your UFOV is opened up again, you use it!
  • You can use DriveSharp repeatedly, over the rest of your days, to keep yourself in fine driving fettle!
  • The second training program that is included in DriveSharp is designed to improve your ability to keep track of more than one thing happening at the same time. This fundamental visual skill — called “multiple object tracking” (MOT) — also dramatically declines as you get older.
  • As you get older, you progressively lose the ability to accurately detect and respond to visual events in your far visual periphery.
  • If you’ve reached your 50th birthday, DriveSharp training is especially important for upgrading and sustaining your driving competence. It’s all about maintaining your performance abilities in driving as in all other ways at the highest possible level, throughout the second half of life.
  • few other benefits demonstrated by published studies originating with the Ball/Roenker team (including University of South Florida scientist Sherri Willis and a University of Iowa scientist, Fred Wolinsky).
  • 1) You’re healthier after DriveSharp training! Five years after training, Physical indices of Quality of Life are more than 30% higher — maybe because you get out more.
  • Trainees are much more likely to have retained your driver’s license — and to have sustained their personal independence.
  • After DriveSharp, you are a more confident driver, as expressed by gains in the number of times you drive each week, by an increase in average driving distances, and by your driving more often at night, or in the rain or snow.
  • Try DriveSharp now: If you are a member of one of the participating AAA clubs, please visit your AAA club’s website for more information and a special offer on DriveSharp. If not, please visit www.DriveSharp.com or call (866)599-6463 to learn more.

Left Brain and Right Brain | Boost Your IQ - 0 views

  • The left brain follows a completely different “way” and process of thinking from the right brain. The left brain sees things in an analytical, objective and logical manner. The right brain on the other hand is more symbol and metaphorically orientated.
  • In order to develop a particular brain, it is therefore necessary to focus on doing things which complement its attributes. For example, if I were to develop my left brain, i would embark on logical analysis and maths. If I were to exercise my right brain, i would indulge in art work.
  • do you see the dancer turning clockwise or anti-clockwise? If clockwise, then you use more of the right side of the brain and vice versa.

Music and Intelligence | Boost Your IQ - 0 views

  • Studies indicate that early exposure to musical training helps a child’s brain reach its potential by generating neural connections utilized in abstract reasoning.
  • The reasoning skills required for a test in spatial reasoning are the same ones children use when they listen to music. Children use these reasoning skills to order the notes in their brain to form the melodies. Also, some concepts of math must be understood in order to understand music. Experts speculate that listening to music exercises the same parts of the brain that handle mathematics, logic, and higher level reasoning.
  • In 1997 a study involving three groups of preschoolers was conducted to determine the effect of music versus computer training on early childhood development.
  • ...9 more annotations...
  • The group that received the piano/keyboard training scored 34% higher on tests measuring spatial-temporal ability than either of the other two groups. These results suggest that music enhances certain higher brain functions, particularly abstract reasoning skills, required in math and science.
  • The use of music in training four and five year old children yielded the highest improvement in the ability to name body parts.
  • Although the three experimental groups displayed an increase in their ability to name body parts the music group exhibited the highest degree of improvement.
  • First grade students received extensive Kodaly training for seven months.
  • At the end of seven months the experimental group had higher reading scores than the control group, which did not receive any special treatment. Not only did the seven month instruction increase reading scores, but continued musical training proved to be beneficial. The experimental group continued to show higher reading scores with continued training.
  • Students who were involved in arts education achieved higher SAT scores. The longer students were involved in arts education, the higher the increase in SAT scores. This study also correlated arts education with higher scores in standardized tests, reading, English, history, citizenship, and geography.
  • The results indicated that students with a relatively lower socioeconomic status, that were exposed to arts education, had an advantage over those students without any arts education which was proportionally equal to the students with a relatively higher socioeconomic status and exposure to arts education.
  • Music exposure affects older students as well. Three groups of college students were exposed to either Mozart’s Sonata for Two Pianos, K448, a relaxation tape, or silence. The group exposed to the Mozart piece was the only group to achieve an increase on the spatial IQ test. Further studies revealed that neither dance music nor taped short stories produced an increase in spatial IQ similar to the Mozart piece. The increase in spatial IQ appears to be related to some unique aspects of the Mozart piece rather than music in general.
  • Music may not only be related to intelligence by its stimulation of the brain, but it may also increase intelligence by the type of attitudes, interests, and discipline it fosters in children.

How To Keep Mentally Fit As You Age | Boost Your IQ - 0 views

  •  
    When you are young and mentally fit, you will perhaps never be able to comprehend that your memory, intelligence and overall mental fitness can actually decline as you age. However, as we grow older, our mental sharpness will gradually decline (and at an increasing rate) if we fail to keep on top of things.

Eide Neurolearning Blog: Recess Essential for Improving Attention - 0 views

  • New research suggests that play and down time may be as important to a child’s academic experience as reading, science and math, and that regular recess, fitness or nature time can influence behavior, concentration and even grades.
  • Young children with sensory processing disorders are especially susceptible to behavioral and attention problems if they are not allowed to move and exercise throughout their day.

Wired 14.02: Buddha on the Brain - 0 views

  • Davidson's research created a stir among brain scientists when his results suggested that, in the course of meditating for tens of thousands of hours, the monks had actually altered the structure and function of their brains.
  • Lutz asked Ricard to meditate on "unconditional loving-kindness and compassion." He immediately noticed powerful gamma activity - brain waves oscillating at roughly 40 cycles per second -�indicating intensely focused thought. Gamma waves are usually weak and difficult to see. Those emanating from Ricard were easily visible, even in the raw EEG output. Moreover, oscillations from various parts of the cortex were synchronized - a phenomenon that sometimes occurs in patients under anesthesia.
  • In the traditional view, the brain becomes frozen with the onset of adulthood, after which few new connections form. In the past 20 years, though, scientists have discovered that intensive training can make a difference. For instance, the portion of the brain that corresponds to a string musician's fingering hand grows larger than the part that governs the bow hand - even in musicians who start playing as adults. Davidson's work suggested this potential might extend to emotional centers
  • ...3 more annotations...
  • The researchers had never seen anything like it. Worried that something might be wrong with their equipment or methods, they brought in more monks, as well as a control group of college students inexperienced in meditation. The monks produced gamma waves that were 30 times as strong as the students'. In addition, larger areas of the meditators' brains were active, particularly in the left prefrontal cortex, the part of the brain responsible for positive emotions.
  • But Davidson saw something more. The monks had responded to the request to meditate on compassion by generating remarkable brain waves. Perhaps these signals indicated that the meditators had attained an intensely compassionate state of mind. If so, then maybe compassion could be exercised like a muscle; with the right training, people could bulk up their empathy. And if meditation could enhance the brain's ability to produce "attention and affective processes" - emotions, in the technical language of Davidson's study - it might also be used to modify maladaptive emotional responses like depression.
  • Davidson and his team published their findings in the Proceedings of the National Academy of Sciences in November 2004. The research made The Wall Street Journal, and Davidson instantly became a celebrity scientist.
