3. Speed It Up
Sorry to say, our brains naturally start slowing down at the cruelly young age of 30 (yes, 30). It used to be thought that this couldn’t be helped, but a barrage of new studies show that people of any age can train their brains to be faster and, in effect, younger. “Your brain is a learning machine,” says Michael Merzenich, PhD, a neuroscientist at the University of California, San Francisco. Given the right tools, we can train our brains to act like they did when we were younger. All that’s required is dedicated practice: exercises for the mind. a barrage of 大量的 in effect 实际上 Merzenich has developed a computer-based training regimen to speed up how the brain processes information (positscience.com). Since much of the data we receive comes through speech, the Brain Fitness Program works with language and hearing to improve both speed and accuracy. Over the course of your training, the program starts asking you to distinguish sounds (between “dog” and “bog,” for instance) at an increasingly faster rate. It’s a bit like a tennis instructor, says Merzenich, shooting balls at you faster and faster over the course of the summer to keep you challenged. Though you may have started out slow, by Labor Day you’re pretty nimble. nimble adj. 敏捷的；聪明的 Similarly, Nintendo was inspired by the research of a Japanese doctor to develop a handheld game called Brain Age: Train Your Brain in Minutes a Day, which has sold more than two million copies in Japan. No software out there has yet been approved by the FDA as a treatment for cognitive impairment, but an increasing number of reputable scientific studies suggest that programs like Merzenich’s could help slow down typical brain aging, or even treat dementia. The biggest finding in brain research in the last ten years is that the brain at any age is highly adaptable, or “plastic,” as neurologists put it. If you ask your brain to learn, it will learn. And it may speed up in the process.
