適度電擊大腦竟讓你變＂數(shù)學達人＂

　　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.

　　專家們稱，這種能夠讓部分大腦“打開”或者“閉合”的方法為一系列問題的解決提供了新思路，這些問題包括計算困難和因動脈急性阻塞造成的視覺損傷等。但是專家警告稱電流作用于大腦的機制還不明確，并對因“反向”電擊而產生數(shù)字認知障礙的志愿者幾個月后能否恢復正常表示懷疑。
