英语时差：电刺激帮助提高数学技能2

Do you have trouble with math? Are there treatments or therapies that can help you get better at mathematics? Good question. And the answer is, yes. Or, at least, there may be. First, though, understand that you’re not alone. Researchers estimate that something like 20% of people have some sort of math disability. Which can be difficult, especially for doing well in school and on standardized tests and the like. Now, doing math is a mental exercise, of course. Some people’s brains seem hard-wired to make sense of numbers. But a group of scientists at Oxford University may have found a way to help people whose brains don’t take as easily to math. Among a group of fifteen volunteers, they used a mild electrical current to stimulate the right hemisphere of the brains of one group, during six two hour sessions. Specifically, they stimulated the parietal lobe the part of the brain linked to working with numbers. The other group was also hooked up to electrodes but received no stimulation.
