适度电击大脑竟让你变＂数学达人＂

　　Experts said that the ability to "turn up" and "turn down" parts of the brain at will open the door to treating a range of problems, from dyscalculia to stroke-related visual damage. But they cautioned that it is not entirely clear how the current affects the brain. And they questioned whether those given the “reverse” current were 'still abnormal' months later.

　　专家们称，这种能够让部分大脑“打开”或者“闭合”的方法为一系列问题的解决提供了新思路，这些问题包括计算困难和因动脉急性阻塞造成的视觉损伤等。但是专家警告称电流作用于大脑的机制还不明确，并对因“反向”电击而产生数字认知障碍的志愿者几个月后能否恢复正常表示怀疑。
