Three researchers, two from United States and a third one from Germany, have reported that the sense of vision is highly advanced in case of people with impaired hearing as a result of the reorganization of the areas of brain reserved for the development and functioning of each senses.

This is to say that the deaf people have better and higher visibility than their normal counterparts and this is because of the fact that the brain has utilized a part of the space reserved for hearing senses towards the higher development of sense of sight. Usually, the deaf people are able to have better peripheral vision and are also able to tell the rate at which a thing is coming towards them. It is analogous to the case where a hearing impaired person cannot sense a car approaching from the side by its sound but they can do so with the help of their advanced peripheral vision.

The brain as the research shows is a very efficient machine and does not let the spaces in the mind go waste, that is to say if one or more senses is underdeveloped, it compensates by enhancing the other senses. The findings were a part of the trials carried on the brains of deaf cats that were deaf by birth that is congenitally deaf cats. Interestingly, cats are the only mammals apart from the homo-sapiens that can be deaf at the time of the birth and continue being so for the rest of the life.
