According to the magazine Scientific American, research on the ability of the brain shows that the brain can "adjust to what happens". The magazine wrote, "A lot of evidence shows that when one senses can no longer convey information to the brain, the brain can adjust the way it works to support and strengthen other senses." Think about the following:

Hearing: The sound of speech or footsteps can help blind people imagine something. Fernando, who is blind, said, "I can remember and know people from sound or even from the way." Juan, who was also blind, said, "Blind people can know people from their voices." They can also know someone's feelings through his voice , just like us.

For blind people who are accustomed to using auditory senses, these senses will help them know many other things such as the direction of traffic, the size of the room, and the location of an object.

Olfaction: This senses can also be a useful source of information, but not just to smell. For example, when a blind person walks across a particular route, his sense of smell can help him memorize the road by remembering the smell of coffee shops, restaurants, markets, and others. Of course, known voices also help. And, information from the sense of touch is also important.

Feeler: Francisco said, "My fingers are my eyes." This "eye" visibility can be extended with a stick. Manasés, who was blind from birth and learned to use a stick when he was a child, said, "I can know the direction of the road because of my other senses, my memories, and the sticks that help me recognize the road conditions that I go through."
