长期以来,人们总认为盲人具有比常人更强的感知能力,以弥补其视觉官能的缺陷。今天看来,这种说法可能真是对的。美国研究人员发现,盲人能够利用触觉使大脑中通往眼睛的神经通路重新接通。美国国立神经病和猝发病研究所的笠恩及其同事称,他们是通过早先的研究得出这一结论的。这些研究表明,盲人在阅读布莱叶盲文时,其大脑视觉皮层常常会被激活。他们对5名视力 For a long time, people always think that blind people have a stronger sense of perception than ordinary people to make up for the defects of their visual functions. Today it seems that this statement may be true. American researchers found that blind people can use the sense of touch to re-connect the nerve path leading to the eye in the brain.

These studies show that when blind people read Braille, their visual cortex in the brain is often activated. They have 5 eyesight
