I often come across articles about how an incompletely developed brain accounts for the emotional problems and irresponsible behavior of teenagers. Is this true, or is it a myth?
It is true that teenagers, by virtue of their hormonal changes, are prone to be emotionally volatile, unpredictable, self-absorbed, and hypersensitive. However, the IMMATURE BRAIN that supposedly causes teen problems is nothing more than a myth. Most of the brain changes that are observed during the teen years lie on a continuum of changes that takes place over much of our lives.
In addition, some of these myths are based on studies of brain activity of teens as compared to adults. But snapshots of brain activities have nothing to do with … >>> READ MORE >>> →
Exercise boosts brainpower and longevity.
Improvement in learning can come from three sources. The first relates to diet. The second relates to sleep. The third is exercise, the subject of this article.
The brain represents only about two percent of most people’s body weight, yet it accounts for about 20 percent of the body’s total energy usage. In addition to its reliance on energy, the brain relies on oxygen, and exercise provides the body greater access to oxygen.
When you understand the biology of exercise, your chances of influencing yourself and your students towards this direction will be enhanced.
One of the greatest predictors of successful living, working, and aging-both mentally and physically-is the absence of a sedentary life style. … >>> READ MORE >>> →
The brain evolved to use light and darkness wisely. Acquire information by day; process it at night.
The effects of sleep on learning and memory are impressive.
Recent discoveries show that sleep facilitates the active analysis of new memories, allows the brain to solve problems, and infer new information. The “sleeping brain” may also be selectively reinforcing the more difficult aspects of a newly learned task.
We may be able to get by on six hours sleep, but if we want to optimize learning and memory, then closer to eight hours is better. Only with more than six hours of sleep does performance improve over the 24 hours following the learning session, according to researchers Robert Stickgold of Harvard University … >>> READ MORE >>> →
